1. Changes to Bash
+a. Fixes to build correctly when arrays are not compiled into the shell.
+
+b. Fixed command substitution to run any exit trap defined in the command
+ substitution before returning; the exit trap is not inherited from the
+ calling shell.
+
+c. Fixes to process group synchronization code so that every child process
+ attempts to set the terminal's process group; fixes some synchronization
+ problems on Linux kernels that schedule the child to always run before
+ the parent.
+
+d. Fixed processing of octal and hex constants in printf builtin for POSIX.2
+ compliance.
+
+e. Fixed a couple of core dumps in the pattern removal code.
+
+f. Fixes to the array subrange extraction code to deal better with sparse
+ arrays.
+
+g. Parser errors and other errors that result in the shell exiting now cause
+ the exit trap to be run.
+
+h. Change the command substitution completion functions to not append any
+ closing quote, because it would be inserted a closing "`" or ")".
+
+i. Fix history initialization so assignments to $histchars made in startup
+ files are honored.
+
+j. If an exit trap does not contain a call to `exit', the shell now uses
+ the exit status of the last command executed before the trap as the exit
+ status of the shell.
+
+k. The parser now prompts with $PS2 if it reads a newline while parsing a
+ compound array assignment statement.
+
+l. When performing a compound array assignment, the parser doesn't treat
+ words of the form [index]=value as assignments if they're the result of
+ expansions.
+
+m. Fixed a bug that caused `return' executed in a trap command to make the
+ shell think it was still running the trap.
+
+n. Fixed the value of errno set by the pathname canonicalization functions.
+
+o. Changed the grammar so that `time' alone on a line times a null command
+ rather than being a syntax error.
+
+p. The pattern substitution coded no longer performs quote removal on the
+ pattern before trying to match it, as the pattern removal functions do.
+
+q. Fixed a bug that could cause core dumps when checking whether a quoted
+ command name was being completed.
+
+r. Fixes to the pattern removal and pattern replacement expansions to deal
+ with multibyte characters better.
+
+s. Fix to the substring expansion (${param:off[:len]}) to deal with (possibly
+ multibyte) characters instead of raw bytes.
+
+2. Changes to Readline
+
+a. Change to history expansion functions to treat `^' as equivalent to word
+ one, as the documention states.
+
+b. Some changes to the display code to improve display and redisplay of
+ multibyte characters.
+
+c. Changes to speed up the multibyte character redisplay code.
+
+d. Fixed a bug in the vi-mode `E' command that caused it to skip over the
+ last character of a word if invoked while point was on the word's
+ next-to-last character.
+
+e. Fixed a bug that could cause incorrect filename quoting when
+ case-insensitive completion was enabled and the word being completed
+ contained backslashes quoting word break characters.
+
+f. Fixed a bug in redisplay triggered when the prompt string contains
+ invisible characters.
+
+3. New Features in Bash
+
+a. printf builtin understands two new escape sequences: \" and \?.
+
+b. `echo -e' understands two new escape sequences: \" and \?.
+
+c. The GNU `gettext' package and libintl have been integrated; the shell's
+ messages can be translated into different languages.
+
+4. New Features in Readline
+
+a. New application variable, rl_completion_quote_character, set to any
+ quote character readline finds before it calls the application completion
+ function.
+
+b. New application variable, rl_completion_suppress_quote, settable by an
+ application completion function. If set to non-zero, readline does not
+ attempt to append a closing quote to a completed word.
+
+c. New application variable, rl_completion_found_quote, set to a non-zero
+ value if readline determines that the word to be completed is quoted.
+ Set before readline calls any application completion function.

+ shell think it was still running the trap.
+
+n. Fixed the value of errno set by the pathname canonicalization functions.
+
+o. Changed the grammar so that `time' alone on a line times a null command
+ rather than being a syntax error.
+
+p. The pattern substitution coded no longer performs quote removal on the
+ pattern before trying to match it, as the pattern removal functions do.
+
+q. Fixed a bug that could cause core dumps when checking whether a quoted
+ command name was being completed.
+
+r. Fixes to the pattern removal and pattern replacement expansions to deal
+ with multibyte characters better.
+
+s. Fix to the substring expansion (${param:off[:len]}) to deal with (possibly
+ multibyte) characters instead of raw bytes.
+
+2. Changes to Readline
+
+a. Change to history expansion functions to treat `^' as equivalent to word
+ one, as the documention states.
+
+b. Some changes to the display code to improve display and redisplay of
+ multibyte characters.
+
+c. Changes to speed up the multibyte character redisplay code.
+
+d. Fixed a bug in the vi-mode `E' command that caused it to skip over the
+ last character of a word if invoked while point was on the word's
+ next-to-last character.
+
+e. Fixed a bug that could cause incorrect filename quoting when
+ case-insensitive completion was enabled and the word being completed
+ contained backslashes quoting word break characters.
+
+f. Fixed a bug in redisplay triggered when the prompt string contains
+ invisible characters.
+
+3. New Features in Bash
+
+a. printf builtin understands two new escape sequences: \" and \?.
+
+b. `echo -e' understands two new escape sequences: \" and \?.
+
+c. The GNU `gettext' package and libintl have been integrated; the shell's
+ messages can be translated into different languages.
+
+4. New Features in Readline
+
+a. New application variable, rl_completion_quote_character, set to any
+ quote character readline finds before it calls the application completion
+ function.
+
+b. New application variable, rl_completion_suppress_quote, settable by an
+ application completion function. If set to non-zero, readline does not
+ attempt to append a closing quote to a completed word.
+
+c. New application variable, rl_completion_found_quote, set to a non-zero
+ value if readline determines that the word to be completed is quoted.
+ Set before readline calls any application completion function.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-3.0-alpha,
+and the previous version, bash-2.05b-release.
+
+1. Changes to Bash
+
+a. Fixes so that the shell will compile without some of the default options
+ defined.
+
+b. Fixed an error message that did not pass enough arguments to printf.
+
+c. Fixed a bug that caused input redirection to a builtin inside a script
+ being read from standard input to result in the rest of the already-
+ read and buffered script to be discarded.
+
+d. Fixed a bug that caused subshell initialization to close the file
+ descriptor from which the shell was reading a script under certain
+ circumstances.
+
+e. Fixed a bug that caused the shell to not advance a string pointer over
+ a null wide character when doing string operations.
+
+f. Fixed the internal logout code so that shells that time out waiting for
+ input (using $TMOUT) run ~/.bash_logout.
+
+g. Portability and configuration changes for: cygwin, HP/UX, GNU/FreeBSD.
+
+h. The parser no longer adds implicit double quotes to ((...)) arithmetic
+ commands.
+
+i. The ((...)) arithmetic command evaluation code was fixed to not dump core
+ when the expanded string is null.
+
+j. The ((...)) arithmetic command evaluation code was fixed to not perform
+ variable assignments while expanding the expression.
+
+k. Fixed a bug that caused word splitting to be performed incorrectly when
+ IFS is set, but null.
+
+l. Fixed a bug in brace expansion that caused a quoted `$' preceding an
+ open brace to inhibit brace expansion.
+
+m. Fixed a bug that caused a leading `-' in the shell's name to cause it to
+ not be recognized as a restricted shell.
+
+n. Fixed a bug in the arithmetic evaluation code that could cause longjmps
+ to an invalid location and result in a core dump.
+
+o. Fixed a bug in the calculation of how many history lines are new in a
+ single shell session when reading new history lines from a file with
+ `history -n'.
+
+p. Fixed a bug in pathname canonicalization that caused the shell to dump
+ core when presented with a pathname longer than PATH_MAX.
+
+q. Fixed the parser so that it doesn't try to compare a char variable to
+ EOF, which fails when chars are unsigned.
+
+r. Fixed a bug in the simple command execution code that caused occasional
+ core dumps.
+
+s. The shell does a better job of saving any partial parsing state during
+ operations which cause a command to be executed while a line is being
+ entered and parsed.
+
+t. The completion code now splits words more like the expansion code when
+ $IFS is used to split.
+
+u. The locale code does a better job of recomputing the various locale
+ variable values when LC_ALL is unset.
+
+v. The programmable completion code does a better job of dequoting expanded
+ word lists before comparing them against the word to be matched.
+
+w. The shell no longer seg faults if the expanded value of $PS4 is null
+ and `set -x' is enabled.
+
+x. Fixed a bug that caused core dumps when a here string expanded to NULL.
+
+y. The mail checking code now makes sure the mailbox is bigger before
+ reporting the existence of new mail.
+
+z. The parser does not try to expand $'...' and $"..." when the appear
+ within double quotes unless the `extquote' option has been enabled with
+ `shopt'. For backwards compatibility, it is enabled by default.
+
+aa. Fixed a bug that caused `for x; do ...' and `select x; do ... to use
+ $@ instead of "$@" for the implicit list of arguments.
+
+bb. Fixed a bug that caused a subshell of a restricted shell (e.g., one
+ spawned to execute a pipeline) to not exit immediately if attempting
+ to use a command containing a slash.
+
+cc. Fixed a problem with empty replacements for a pattern that doesn't match
+ when performing ${param/word/} expansion.
+
+dd. Word expansions performed while expanding redirections no longer search
+ a command's temporary environment to expand variable values.
+
+ee. Improvements to the alias expansion code when expanding subsequent words
+ because an aliase's value ends with a space.
+
+ff. `cd -' now prints the current working directory after a successful chdir
+ even when the shell is not interactive, as the standard requires.
+
+gg. The shell does a better job of ensuring a child process dies of SIGINT
+ before resending SIGINT to itself.
+
+hh. The arithmetic expansion variable assignment code now does the right
+ thing when assigning to `special' variables like OPTIND.
+
+ii. When history expansion verification is enabled, the bash readline helper
+ functions that do history expansion on the current line don't print
+ the results.
+
+jj. Fixed bugs with multiple consecutive alias expansion when one of the
+ expansions ends with a space.
+
+kk. Fixed a problem in the programmable completion code that could cause core
+ dumps when trying to initialize a set of possible completions from a
+ list of variables.
+
+ll. The \[ and \] escape characters are now ignored when decoding the prompt
+ string if the shell is started with editing disabled.
+
+mm. Fixed a bug that could leave extra characters in a string when doing
+ quoted null character removal.
+
+nn. Command substitution and other subshell operations no longer reset the
+ line number (aids the bash debugger).
+
+oo. Better line number management when executing simple commands, conditional
+ commands, for commands, and select commands.
+
+pp. The globbing code now uses malloc, with its better failure properties,
+ rather than alloca().
+
+qq. Fixed a bug that caused expansions like #{a[2]:=value} to create the
+ appropriate array element instead of a variable named `a[2]'.
+
+rr. Fixed a bug in the handling of a `?(...)' pattern immediately following
+ a `*' when extglob is enabled.
+
+ss. Fixed a bug that caused a `return' invoked in an exit trap when exit is
+ invoked in a function to misbehave.
+
+tt. Fixed a bug that caused CTLESC and CTLNUL characters to not be escaped
+ by the internal shell string quoting functions.
+
+uu. Fixed a bug that caused quoted null characters in an expanded word list
+ to be inappropriately assigned to an array variable when using `read -a'.
+
+vv. Fixed a bug that caused redirections accompanying a null command to persist
+ in the current shell.
+
+ww. Fixed a bug that caused the prompt to be printed when the shell was
+ expanding a multiline alias.
+
+xx. Fixed a bug that resulted in core dumps when the completion for a command
+ changed the compspec.
+
+yy. Fixed a bug that caused evaluation of programmable completions to print
+ notifications of completed jobs.
+
+zz. Bash now disables line editing when $EMACS == `t' and $TERM == `dumb'
+ (which is what emacs shell windows do).
+
+aaa. In posix mode, `kill -l' causes signal names to be displayed without
+ a leading `SIG'.
+
+bbb. Clear error flag on standard output so it doesn't persist across multiple
+ builtin commands.
+
+ccc. In posix mode, `alias' displays alias values without the leading `alias',
+ so the output cannot be used as subsequent input.
+
+ddd. In posix mode, the `trap' builtin doesn't check whether or not its
+ first argument is a signal specification and revert the signal handling
+ to its original disposition if it is.
+
+eee. Fixed several bugs in the handling of "$*" and "${array[*]}" by the
+ pattern substitution and removal expansions.
+
+fff. Fixed several problems with the handling of ${array[@]}, ${array[*]},
+ $@, and $* by the indirect variable expansion code.
+
+ggg. Fixed a bug that did not allow `time' to be aliased.
+
+hhh. Improved the mail checking code so it won't check (and possibly cause an
+ NFS file system mount) until MAILPATH or MAIL is given a value -- there
+ is no default if DEFAULT_MAIL_DIRECTORY is not defined at compile time.
+ (It is computed by configure, but can be #undef'd in config-bot.h.)
+
+iii. If the `chkwinsize' option is enabled, the shell checks for window size
+ changes if a child process exits due to a signal.
+
+jjj. Removed the attempts to avoid adding a slash at the end of a completed
+ executable name if there was a directory with the same name in the
+ current directory.
+
+kkk. Fixed PATH lookup code so it treats the permission bits separately for
+ owner, group, and other, rather than checking them all.
+
+lll. Fixed the locale code to reset the parser's idea of the character class
+ <blank>, which controls how it splits tokens, when the locale changes.
+
+mmm. The shell now binds its special readline functions and key bindings only
+ if the user's inputrc file has not already bound them.
+
+nnn. The shell now reports on processes that dump core due to signals when
+ invoked as `-c command'.
+
+2. Changes to Readline
+
+a. Fixes to avoid core dumps because of null pointer references in the
+ multibyte character code.
+
+b. Fix to avoid infinite recursion caused by certain key combinations.
+
+c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
+
+d. Readline no longer tries to read ahead more than one line of input, even
+ when more is available.
+
+e. Fixed the code that adjusts the point to not mishandle null wide
+ characters.
+
+f. Fixed a bug in the history expansion `g' modifier that caused it to skip
+ every other match.
+
+g. Fixed a bug that caused the prompt to overwrite previous output when the
+ output doesn't contain a newline and the locale supports multibyte
+ characters. This same change fixes the problem of readline redisplay
+ slowing down dramatically as the line gets longer in multibyte locales.
+
+h. History traversal with arrow keys in vi insertion mode causes the cursor
+ to be placed at the end of the new line, like in emacs mode.
+
+i. The locale initialization code does a better job of using the right
+ precedence and defaulting when checking the appropriate environment
+ variables.
+
+j. Fixed the history word tokenizer to handle <( and >( better when used as
+ part of bash.
+
+k. The overwrite mode code received several bug fixes to improve undo.
+
+l. Many speedups to the multibyte character redisplay code.
+
+m. The callback character reading interface should not hang waiting to read
+ keyboard input.
+
+n. Fixed a bug with redoing vi-mode `s' command.
+
+o. The code that initializes the terminal tracks changes made to the terminal
+ special characters with stty(1) (or equivalent), so that these changes
+ are reflected in the readline bindings. New application-callable function
+ to make it work: rl_tty_unset_default_bindings().
+
+p. Fixed a bug that could cause garbage to be inserted in the buffer when
+ changing character case in vi mode when using a multibyte locale.
+
+q. Fixed a bug in the redisplay code that caused problems on systems
+ supporting multibyte characters when moving between history lines when the
+ new line has more glyphs but fewer bytes.
+
+r. Undo and redo now work better after exiting vi insertion mode.
+
+s. Make sure system calls are restarted after a SIGWINCH is received using
+ SA_RESTART.
+
+t. Improvements to the code that displays possible completions when using
+ multibyte characters.
+
+u. Fixed a problem when parsing nested if statements in inputrc files.
+
+v. The completer now takes multibyte characters into account when looking for
+ quoted substrings on which to perform completion.
+
+w. The history search functions now perform better bounds checking on the
+ history list.
+
+3. New Features in Bash
+
+a. ANSI string expansion now implements the \x{hexdigits} escape.
+
+b. There is a new loadable `strftime' builtin.
+
+c. New variable, COMP_WORDBREAKS, which controls the readline completer's
+ idea of word break characters.
+
+d. The `type' builtin no longer reports on aliases unless alias expansion
+ will actually be performed.
+
+e. HISTCONTROL is now a colon-separated list of values, which permits
+ more extensibility and backwards compatibility.
+
+f. HISTCONTROL may now include the `erasedups' option, which causes all lines
+ matching a line being added to be removed from the history list.
+
+g. `configure' has a new `--enable-multibyte' argument that permits multibyte
+ character support to be disabled even on systems that support it.
+
+h. New variables to support the bash debugger: BASH_ARGC, BASH_ARGV,
+ BASH_SOURCE, BASH_LINENO, BASH_SUBSHELL, BASH_EXECUTION_STRING,
+ BASH_COMMAND
+
+i. FUNCNAME has been changed to support the debugger: it's now an array
+ variable.
+
+j. for, case, select, arithmetic commands now keep line number information
+ for the debugger.
+
+k. There is a new `RETURN' trap executed when a function or sourced script
+ returns (not inherited child processes; inherited by command substitution
+ if function tracing is enabled and the debugger is active).
+
+l. New invocation option: --debugger. Enables debugging and turns on new
+ `extdebug' shell option.
+
+m. New `functrace' and `errtrace' options to `set -o' cause DEBUG and ERR
+ traps, respectively, to be inherited by shell functions. Equivalent to
+ `set -T' and `set -E' respectively. The `functrace' option also controls
+ whether or not the DEBUG trap is inherited by sourced scripts.
+
+n. The DEBUG trap is run before binding the variable and running the action
+ list in a `for' command, binding the selection variable and running the
+ query in a `select' command, and before attempting a match in a `case'
+ command.
+
+o. New `--enable-debugger' option to `configure' to compile in the debugger
+ support code.
+
+p. `declare -F' now prints out extra line number and source file information
+ if the `extdebug' option is set.
+
+q. If `extdebug' is enabled, a non-zero return value from a DEBUG trap causes
+ the next command to be skipped, and a return value of 2 while in a
+ function or sourced script forces a `return'.
+
+r. New `caller' builtin to provide a call stack for the bash debugger.
+
+s. The DEBUG trap is run just before the first command in a function body is
+ executed, for the debugger.
+
+t. `for', `select', and `case' command heads are printed when `set -x' is
+ enabled.
+
+u. There is a new {x..y} brace expansion, which is shorthand for {x.x+1,
+ x+2,...,y}. x and y can be integers or single characters; the sequence
+ may ascend or descend; the increment is always 1.
+
+v. New ksh93-like ${!array[@]} expansion, expands to all the keys (indices)
+ of array.
+
+w. New `force_fignore' shopt option; if enabled, suffixes specified by
+ FIGNORE cause words to be ignored when performing word completion even
+ if they're the only possibilities.
+
+x. New `gnu_errfmt' shopt option; if enabled, error messages follow the `gnu
+ style' (filename:lineno:message) format.
+
+y. New `-o bashdefault' option to complete and compgen; if set, causes the
+ whole set of bash completions to be performed if the compspec doesn't
+ result in a match.
+
+z. New `-o plusdirs' option to complete and compgen; if set, causes directory
+ name completion to be performed and the results added to the rest of the
+ possible completions.
+
+aa. `kill' is available as a builtin even when the shell is built without
+ job control.
+
+bb. New HISTTIMEFORMAT variable; value is a format string to pass to
+ strftime(3). If set and not null, the `history' builtin prints out
+ timestamp information according to the specified format when displaying
+ history entries. If set, bash tells the history library to write out
+ timestamp information when the history file is written.
+
+cc. The [[ ... ]] command has a new binary `=~' operator that performs
+ extended regular expression (egrep-like) matching.
+
+dd. `configure' has a new `--enable-cond-regexp' option (enabled by default)
+ to enable the =~ operator and regexp matching in [[ ... ]].
+
+ee. Subexpressions matched by the =~ operator are placed in the new
+ BASH_REMATCH array variable.
+
+ff. New `failglob' option that causes an expansion error when pathname
+ expansion fails to produce a match.
+
+gg. New `set -o pipefail' option that causes a pipeline to return a failure
+ status if any of the processes in the pipeline fail, not just the last
+ one.
+
+4. New Features in Readline
+
+a. History expansion has a new `a' modifier equivalent to the `g' modifier
+ for compatibility with the BSD csh.
+
+b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
+ modifier, which performs a substitution once per word.
+
+c. All non-incremental search operations may now undo the operation of
+ replacing the current line with the history line.
+
+d. The text inserted by an `a' command in vi mode can be reinserted with
+ `.'.
+
+e. New bindable variable, `show-all-if-unmodified'. If set, the readline
+ completer will list possible completions immediately if there is more
+ than one completion and partial completion cannot be performed.
+
+f. There is a new application-callable `free_history_entry()' function.
+
+g. History list entries now contain timestamp information; the history file
+ functions know how to read and write timestamp information associated
+ with each entry.
+
+h. Four new key binding functions have been added:
+
+ rl_bind_key_if_unbound()
+ rl_bind_key_if_unbound_in_map()
+ rl_bind_keyseq_if_unbound()
+ rl_bind_keyseq_if_unbound_in_map()
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-release,
+and the previous version, bash-2.05b-beta2.
+
+1. Changes to Bash
+
+a. Fixed an off-by-one error in the function that translates job
+ specifications.
+
+b. Note that we're running under Emacs and disable line editing if
+ $EMACS == `t'.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-beta2,
+and the previous version, bash-2.05b-beta1.
+
+1. Changes to Bash
+
+a. Fixed the /= and %= arithmetic operators to catch division by zero.
+
+b. Added putenv, setenv, unsetenv to getenv replacement for completeness.
+
+c. Fixed a bug that could cause the -O expand_aliases invocation option
+ to not take effect.
+
+d. Fixed a problem with process substitution that resulted in incorrect
+ behavior when the number of process substitutions in an individual
+ command approached 64.
+
+2. Changes to Readline
+
+a. Fixed a problem with backward-char-search when on a system with support
+ for multibyte characters when running in a locale without any multibyte
+ characters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-beta1,
+and the previous version, bash-2.05b-alpha1.
+
+1. Changes to Bash
+
+a. Fixed a problem when parsing a POSIX.2 character class name while
+ evaluating a bracket expression containing multibyte characters.
+
+b. Changed the help text for `bind' to make it clear that any command
+ that may be placed in ~/.inputrc is a valid argument to `bind'.
+
+c. Added `help' builtin entries for `((', `[[', and arithmetic for.
+
+d. malloc updated again:
+ o slightly better overflow and underflow detection by putting the
+ chunk size at the beginning and end of the chunk and making
+ sure they match in free/realloc
+ o partial page allocated to make things page-aligned no longer
+ completely wasted
+ o block coalescing now enabled by default
+ o splitting and coalescing enabled for 32-byte chunks, the most
+ common size requested
+ o fixed a problem that resulted in spurious underflow messages and
+ aborts
+ o bin sizes are precomputed and stored in an array rather than
+ being computed at run time
+ o malloc will return memory blocks back to the system if the block
+ being freed is at the top of the heap and of sufficient size to
+ make it worthwhile
+ o malloc/free/realloc now inline memset instead of calling the
+ libc function; uses Duff's device for good performance
+
+e. Check for getservent(); make the service name completion code dependent
+ on its presence.
+
+f. Changed the readline callback that executes a command bound to a key
+ sequence to not save the executed command on the history list and to
+ save and restore the parsing state.
+
+g. Changes to lib/sh/snprintf.c: fixed some bugs in the `g' and `G'
+ floating point format display; implemented the "'" flag character
+ that turns on thousands' grouping; fixed behavior on systems where
+ MB_CUR_MAX does not evaluate to a constant.
+
+h. The `unset' builtin no longer returns a failure status when asked to
+ unset a previously-unset variable or function.
+
+i. Changes to the build system to make it easier to cross-compile bash
+ for different systems.
+
+j. Added `,' to the characters that are backslash-escaped during filename
+ completion, to avoid problems with complete-into-braces and RCS filenames
+ containing commas.
+
+k. Some changes to the multibyte character support code to avoid many calls
+ to strlen().
+
+l. Bash now correctly honors setting LANG to some value when LC_ALL does not
+ already have a value.
+
+m. Fixed a bug that could cause SIGSEGV when processing nested traps with
+ trap handlers.
+
+n. The `source/.' builtin now restores the positional parameters when it
+ returns unless they were changed using the `set' builtin during the file's
+ execution.
+
+o. Fixed a bug that caused a syntax error when a command was terminated by
+ EOF.
+
+2. New Features in Bash
+
+a. There is now support for placing the long help text into separate files
+ installed into ${datadir}/bash. Not enabled by default; can be turned
+ on with `--enable-separate-helpfiles' option to configure.
+
+b. All builtins that take operands accept a `--' pseudo-option, except
+ `echo'.
+
+c. The `echo' builtin now accepts \0xxx (zero to three octal digits following
+ the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/
+ POSIX.1-2001 compliance.
+
+3. Changes to Readline
+
+a. Fixed a small problem in _rl_insert_char with multibyte characters.
+
+b. Fixes from IBM for line wrapping problems when using multibyte characters.
+
+c. Fixed a problem which caused the display to be messed up when the last
+ line of a multi-line prompt (possibly containing invisible characters)
+ was longer than the screen width.
+
+d. Fixed a problem with the vi-mode `r' command that ocurred on systems with
+ support for multibyte characters when running in a locale without any
+ multibyte characters.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05b-alpha1,
+and the previous version, bash-2.05a-release.
+
+1. Changes to Bash
+
+a. Some changes to work around inlining differences between compilers.
+
+b. Added more prototypes for internal shell typedefs, to catch argument
+ passing errors when using pointers to functions.
+
+c. The `cd' builtin now fails in posix mode when a valid directory cannot be
+ constructed from a relative pathname argument and the $PWD using pathname
+ canonicalization, and the -P option has not been supplied. Previously,
+ the shell would attempt to use what the user typed, leading to weird
+ values for $PWD and discrepancies between the value of $PWD and the
+ actual working directory.
+
+d. The `cd' builtin now resets $PWD when canonicalization fails but a chdir
+ to the pathname passed as an argument succeeds (when not in posix mode).
+
+e. The `fc' builtin has been fixed, as POSIX requires, to use the closest
+ history position in range when given an out-of-range argument.
+
+f. The history file loading code was changed to allow lines to be saved in
+ the history list from the shell startup files.
+
+g. `history -s args' now works better in compound commands.
+
+h. The tilde expansion code was fixed to better recognize when it's being
+ invoked in an assignment context, which enables expansion after `='
+ and `:'.
+
+i. Fixed the command name completion code so a slash is no longer appended
+ to a single match if there happens to be a directory with that name in
+ $PWD.
+
+j. Fixed compound array assignment to no longer perform alias expansion, to
+ allow reserved words as array members, and to not produce extra output
+ when the `-v' option had been enabled.
+
+k. Fixed the programmable completion code to better handle newlines in lists
+ of possible completions (e.g., `complete -W').
+
+l. Removed the reserved words from the `bash-builtins' manual page.
+
+m. Parser error reporting now attempts to do a better job of identifying the
+ token in error rather than doing straight textual analysis.
+
+n. Fixes for Inf/NaN, locales, wide/multibyte characters and zero-length
+ arguments in the library snprintf(3) replacement.
+
+o. `read -e' no longer does command name completion on the first word on
+ the line being read.
+
+p. `select' now returns failure if the read of the user's selection fails.
+
+q. Fixed a bug that could cause a core dump when setting $PIPESTATUS.
+
+r. Fixes to not allocate so many job slots when the shell is running a loop
+ with job control enabled in a subshell of an interactive shell.
+
+s. Fixed a bug in the trap code that caused traps to be inherited by
+ command substitutions in some cases.
+
+t. Fixed a bug that could cause alias expansion to inappropriately expand
+ the word following the alias.
+
+u. Fixed a bug in the `kill' builtin that mishandled negative pid arguments.
+
+v. The parser is less lenient when parsing assignment statements where the
+ characters before the `=' don't comprise a valid identifier.
+
+w. The arithmetic expression evaluation code now honors the setting of the
+ `-u' option when expanding variable names.
+
+x. Fixed the arithmetic evaluation code to allow array subscripts to be
+ assigned (`let b[7]=42') and auto-incremented and auto-decremented
+ (e.g., b[7]++).
+
+y. Reimplemented the existing prompt string date and time expansions using
+ strftime(3), which changed the output of \@ in some locales.
+
+z. Fixed a bug that could cause a core dump when a special shell variable
+ (like RANDOM) was converted to an array with a variable assignment.
+
+aa. Fixed a bug that would reset the handler for a signal the user had
+ trapped to a function that would exit the shell when setting the exit
+ trap in a non-interactive shell.
+
+bb. Changed the execve(2) wrapper code to check whether or not a failing
+ command is a directory before looking at whether a `#!' interpreter
+ failed for some reason.
+
+cc. Fixed a bug in the command printing code so it no longer inserts a `;'
+ after a newline, which produces a syntax error when reused as input.
+
+dd. The code that expands $PS4 no longer inherits the `-x' flag.
+
+ee. The bash-specific completion functions may now take advantage of the
+ double-TAB and M-? features of the standard readline completion
+ functions.
+
+ff. The mail checking code no longer prints a message if the checked file's
+ size has not increased, even if the access time is less than the modification time.
+
+gg. Rewrote the variable symbol table code: there is now a stack of
+ contexts, each possibly including a separate symbol table; there can
+ be more than one temporary environment supplied to nested invocations
+ of `./source'; the temporary environments no longer require so much
+ special-case code; shell functions now handle the temporary environment
+ and local variables more consistently; function scope exit is faster now
+ that the entire symbol table does not have to be traversed to dispose of
+ local variables; it is now easier to push vars from the temporary
+ environment to the shell's variable table in posix mode; some duplicated
+ code has been removed.
+
+hh. Regularized the error message printing code; builtin_error is now called
+ more consistently, and common error message strings are handled by small
+ functions. This should make eventual message translation easier.
+
+ii. Error messages now include the line number in a script when the shell
+ is not interactive.
+
+jj. Array subscript expansion now takes place even when the array variable is
+ unset, so side effects will take place.
+
+kk. Fixed a bug in the SICGHLD child-reaping code so that it won't find
+ jobs already marked as terminated if the OS reuses pids quickly enough.
+
+ll. Fixed a bug that could cause a signal to not interrupt the `wait'
+ builtin while it was waiting for a background process to terminate.
+
+mm. A couple of changes to make it easier for multiple shells to share history
+ files using `history -n', `history -r', and `history -w'.
+
+nn. The `getopts' builtin always increments OPTIND to point to the next
+ option to be handled when an option is returned, whether it's valid
+ or not, as POSIX 1003.x-2001 requires.
+
+oo. Changed some parts of the expansion code to avoid allocating and
+ immediately freeing memory without using the results for anything.
+
+pp. The shell now keeps track of $IFS internally, updating its internal map
+ each time the variable is assigned a new value (or at local scope exit).
+ This saves thousands of hash lookups for IFS, which, while individually
+ cheap, add up.
+
+qq. Rewrote the hash table code: searching and insertion are much faster now,
+ and it uses a better string hashing function; augmented the function
+ interface to simplify other parts of the code and remove duplicated code
+
+rr. The shell now uses a simple, generic `object cache' for allocating and
+ caching words and word lists, which were the major users of
+ malloc/free.
+
+ss. Fixed the assignment statement parsing code to allow whitespace and
+ newlines in subscripts when performing array element assignment.
+
+tt. The shell now issues many fewer calls to sigprocmask and other signal
+ masking system calls.
+
+uu. Fixed the `test' and conditional command file comparison operators to
+ work right when one file has a non-positive timestamp and the other
+ does not exist.
+
+vv. Fixed some cases where the special characters '\001' and '\177' in the
+ values of variables or positional parameters caused incorrect expansion
+ results.
+
+2. Changes to Readline
+
+a. Fixed output of comment-begin character when listing variable values.
+
+b. Added some default key bindings for common escape sequences produced by
+ HOME and END keys.
+
+c. Fixed the mark handling code to be more emacs-compatible.
+
+d. A bug was fixed in the code that prints possible completions to keep it
+ from printing empty strings in certain circumstances.
+
+e. Change the key sequence printing code to print ESC as M\- if ESC is a
+ meta-prefix character -- it's easier for users to understand than \e.
+
+f. Fixed unstifle_history() to return values that match the documentation.
+
+g. Fixed the event loop (rl_event_hook) to handle the case where the input
+ file descriptor is invalidated.
+
+h. Fixed the prompt display code to work better when the application has a
+ custom redisplay function.
+
+i. Changes to make reading and writing the history file a little faster, and
+ to cope with huge history files without calling abort(3) from xmalloc.
+
+j. The vi-mode `S' and `s' commands are now undone correctly.
+
+3. New Features in Bash
+
+a. If set, TMOUT is the default timeout for the `read' builtin.
+
+b. `type' has two new options: `-f' suppresses shell function lookup, and
+ `-P' forces a $PATH search.
+
+c. New code to handle multibyte characters.
+
+d. `select' was changed to be more ksh-compatible, in that the menu is
+ reprinted each time through the loop only if REPLY is set to NULL.
+ The previous behavior is available as a compile-time option.
+
+e. `complete -d' and `complete -o dirnames' now force a slash to be
+ appended to names which are symlinks to directories.
+
+f. There is now a bindable edit-and-execute-command readline command,
+ like the vi-mode `v' command, bound to C-xC-e in emacs mode.
+
+g. Added support for ksh93-like [:word:] character class in pattern matching.
+
+h. The $'...' quoting construct now expands \cX to Control-X.
+
+i. A new \D{...} prompt expansion; passes the `...' to strftime and inserts
+ the result into the expanded prompt.
+
+j. The shell now performs arithmetic in the largest integer size the
+ machine supports (intmax_t), instead of long.
+
+k. If a numeric argument is supplied to one of the bash globbing completion
+ functions, a `*' is appended to the word before expansion is attempted.
+
+l. The bash globbing completion functions now allow completions to be listed
+ with double tabs or if `show-all-if-ambiguous' is set.
+
+m. New `-o nospace' option for `complete' and `compgen' builtins; suppresses
+ readline's appending a space to the completed word.
+
+n. New `here-string' redirection operator: <<< word.
+
+o. When displaying variables, function attributes and definitions are shown
+ separately, allowing them to be re-used as input (attempting to re-use
+ the old output would result in syntax errors).
+
+p. There is a new configuration option `--enable-mem-scramble', controls
+ bash malloc behavior of writing garbage characters into memory at
+ allocation and free time.
+
+q. The `complete' and `compgen' builtins now have a new `-s/-A service'
+ option to complete on names from /etc/services.
+
+r. `read' has a new `-u fd' option to read from a specified file descriptor.
+
+s. Fix the completion code so that expansion errors in a directory name
+ don't cause a longjmp back to the command loop.
+
+t. Fixed word completion inside command substitution to work a little more
+ intuitively.
+
+u. The `printf' %q format specifier now uses $'...' quoting to print the
+ argument if it contains non-printing characters.
+
+v. The `declare' and `typeset' builtins have a new `-t' option. When applied
+ to functions, it causes the DEBUG trap to be inherited by the named
+ function. Currently has no effect on variables.
+
+w. The DEBUG trap is now run *before* simple commands, ((...)) commands,
+ [[...]] conditional commands, and for ((...)) loops.
+
+x. The expansion of $LINENO inside a shell function is only relative to the
+ function start if the shell is interactive -- if the shell is running a
+ script, $LINENO expands to the line number in the script. This is as
+ POSIX-2001 requires.
+
+y. The bash debugger in examples/bashdb has been modified to work with the
+ new DEBUG trap semantics, the command set has been made more gdb-like,
+ and the changes to $LINENO make debugging functions work better. Code
+ from Gary Vaughan.
+
+z. New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup
+ and close).
+
+aa. There is a new `-l' invocation option, equivalent to `--login'.
+
+bb. The `hash' builtin has a new `-l' option to list contents in a reusable
+ format, and a `-d' option to remove a name from the hash table.
+
+4. New Features in Readline
+
+a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
+ be bound to readline functions. Now the arrow keys may be used in vi
+ insert mode.
+
+b. When listing completions, and the number of lines displayed is more than
+ the screen length, readline uses an internal pager to display the results.
+ This is controlled by the `page-completions' variable (default on).
+
+c. New code to handle editing and displaying multibyte characters.
+
+d. The behavior introduced in bash-2.05a of deciding whether or not to
+ append a slash to a completed name that is a symlink to a directory has
+ been made optional, controlled by the `mark-symlinked-directories'
+ variable (default is the 2.05a behavior).
+
+e. The `insert-comment' command now acts as a toggle if given a numeric
+ argument: if the first characters on the line don't specify a
+ comment, insert one; if they do, delete the comment text
+
+f. New application-settable completion variable:
+ rl_completion_mark_symlink_dirs, allows an application's completion
+ function to temporarily override the user's preference for appending
+ slashes to names which are symlinks to directories.
+
+g. New function available to application completion functions:
+ rl_completion_mode, to tell how the completion function was invoked
+ and decide which argument to supply to rl_complete_internal (to list
+ completions, etc.).
+
+h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
+ bindable command, which could be bound to `Insert'.
+
+i. New application-settable completion variable:
+ rl_completion_suppress_append, inhibits appending of
+ rl_completion_append_character to completed words.
+
+j. New key bindings when reading an incremental search string: ^W yanks
+ the currently-matched word out of the current line into the search
+ string; ^Y yanks the rest of the current line into the search string,
+ DEL or ^H deletes characters from the search string.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-release,
+and the previous version, bash-2.05a-rc1.
+
+1. Changes to Bash
+
+a. Fixed the `printf' builtin so that the variable name supplied as an
+ argument to a %n conversion must be a valid shell identifier.
+
+b. Improved the random number generator slightly.
+
+c. Changes to configuration to not put -I/usr/include into $CFLAGS, since
+ it messes up some includes.
+
+d. Corrected description of POSIXLY_CORRECT in man page and info manual.
+
+e. Fixed a couple of cases of incorrect function prototypes that sneaked
+ through and caused compilation problems.
+
+f. A few changes to avoid potential core dumps in the programmable completion
+ code.
+
+g. Fixed a configure problem that could cause a non-existent file to show
+ up in LIBOBJS.
+
+h. Fixed a configure problem that could cause siglist.o to not be built when
+ required.
+
+i. Changes to the strtoimax and strtoumax replacement functions to work
+ around buggy compilers.
+
+j. Fixed a problem with the snprintf replacement function that could
+ potentially cause a core dump.
+
+2. Changes to Readline
+
+a. Fixed a locale-specific problem in the vi-mode `goto mark' command.
+
+b. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
+ include file problems.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-rc1,
+and the previous version, bash-2.05a-beta1.
+
+1. Changes to Bash
+
+a. Fixed the snprintf replacement to correctly implement the `alternate form'
+ of the %g and %G conversions.
+
+b. Fixed snprintf to correctly handle the optional precision with the %g and
+ %G conversions.
+
+c. Fixed the arithmetic evaluation code to correct the values of `@' and `_'
+ when translating base-64 constants (they were backwards).
+
+d. New library functions for formatting long and long long ints.
+
+e. Fixed a few places where negative array subscripts could have occurred,
+ mostly as the result of systems using signed characters.
+
+f. Fixed a few places that assumed a pid_t was no wider than an int.
+
+g. Fixed the `maildir' mail checking code to work on systems where a
+ `struct stat' doesn't include an `st_blocks' member.
+
+h. Fixed snprintf to make `unsigned long long' conversion formats (%llu)
+ work better.
+
+i. Fixed snprintf to not print a sign when asked to do an unsigned conversion.
+
+j. Made configure changes to avoid compiling empty source files in lib/sh.
+
+k. New replacement functions (if necessary) for strtoull, strtoll, strtoimax,
+ strtoumax.
+
+l. The `printf' builtin now handles the `ll' and `j' length modifiers
+ directly, since they can affect the type and width of the argument
+ passed to printf(3).
+
+m. Renamed a number of the bash-specific autoconf macros in aclocal.m4 to
+ have more sytematic naming, with accompanying changes to configure.in.
+
+n. Fixed snprintf to handle long doubles and the %a/%A conversions by
+ falling back to sprintf, as long as sprintf supports them.
+
+o. Fixed return value from vsnprintf/snprintf to be the number of characters
+ that would have been printed, even if that number exceeds the buffer
+ size passed as an argument.
+
+p. Bash no longer attempts to define its own versions of some ctype macros
+ if they are implemented as functions in libc but not as macros in
+ <ctype.h>.
+
+q. Changed the variable printing code (used by `set', `export', etc.) to
+ not use the $'...' syntax when in posix mode, since that caused
+ interoperability problems with other shells (most notably with autoconf).
+ When not in posix mode, it uses $'...' if the string to be printed
+ contains non-printing characters and regular single quotes otherwise.
+
+r. snprintf now recognizes the %F conversion.
+
+s. Fixed a bug that could cause the wrong status to be returned by a shell
+ function when the shell is compiled without job control and a null
+ command containing a command substutition was executed in the function.
+
+t. When in posix mode, the default value for MAILCHECK is 600.
+
+u. Bash only initializes FUNCNAME, GROUPS, and DIRSTACK as special variables
+ if they're not in the initial environment.
+
+v. If SECONDS appears in the initial environment with a valid integer value,
+ bash uses that as the starting value, as if an assignment had been
+ performed.
+
+w. Bash no longer auto-exports HOME, PATH, SHELL, or TERM, even though it
+ gives them default values if they don't appear in the initial environment.
+
+x. Bash no longer auto-exports HOSTNAME, HOSTTYPE, MACHTYPE, or OSTYPE,
+ even if it assigns them default values.
+
+y. Bash no longer removes the export attribute from SSH_CLIENT or SSH2_CLIENT
+ if they appear in the initial environment.
+
+z. Bash no longer attempts to discover if it's being run by sshd in order to
+ run the startup files. If the SSH_SOURCE_BASHRC is uncommented in
+ config-top.h it will attempt to do so as previously, but that's commented
+ out in the distributed version.
+
+aa. Fixed a typo in the code that tests for LC_NUMERIC.
+
+bb. The POSIXLY_CORRECT shell variable and its effects are now documented.
+
+cc. Some changes to several of the support shell scripts included in the
+ definitions to try to avoid race conditions and attacks.
+
+dd. Several changes to avoid warnings from `gcc -Wall'.
+
+ee. Fixed a problem with the `unset' builtin that could cause incorrect
+ results if asked to unset a variable and an array subscript in the
+ same command.
+
+ff. A few changes to the shell's temporary file creation code to avoid
+ potential file descriptor leaks and to prefer the system's idea of
+ the temporary directory to use.
+
+gg. Fixes to build with the C alloca in lib/malloc/alloca.c if the system
+ requires it but the shell has been configured --without-bash-malloc.
+
+hh. Updated the documentation to note that only interactive shells resend
+ SIGHUP to all jobs before exiting.
+
+ii. Fixes to only pass unquoted tilde words to tilde_expand, rather than
+ rely on tilde_expand or getpwnam(3) to handle the quotes (MacOS 10.x
+ will remove backslashes in any login name passed to getpwnam(3)).
+
+jj. Small change from Paul Eggert to make LINENO right in commands run with
+ `bash -c'.
+
+2. New Features in Bash
+
+a. The `printf' builtin now handles the %a and %A conversions if they're
+ implemented by printf(3).
+
+b. The `printf' builtin now handles the %F conversion (just about like %f).
+
+c. The `printf' builtin now handles the %n conversion like printf(3). The
+ corresponding argument is the name of a shell variable to which the
+ value is assigned.
+
+3. Changes to Readline
+
+a. Fixed a few places where negative array subscripts could have occurred.
+
+b. Fixed the vi-mode code to use a better method to determine the bounds of
+ the array used to hold the marks.
+
+c. Fixed the defines in chardefs.h to work better when chars are signed.
+
+d. Fixed configure.in to use the new names for bash autoconf macros.
+
+e. Readline no longer attempts to define its own versions of some ctype
+ macros if they are implemented as functions in libc but not as macros in
+ <ctype.h>.
+
+f. Fixed a problem where rl_backward could possibly set point to before
+ the beginning of the line.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-beta1,
+and the previous version, bash-2.05a-alpha1.
+
+1. Changes to Bash
+
+a. Fixed a bug in the evalution of arithmetic `for' statements when the
+ expanded expression is NULL.
+
+b. Fixed an unassigned variable problem in the redirection printing code.
+
+c. Added more prototypes to extern function declarations in the header
+ files and to static function declarations in C source files.
+
+d. Make sure called functions have a prototype in scope, to get the arguments
+ and return values right instead of casting. Removed extern function
+ declarations from C source files that were already included in header
+ files.
+
+e. Changed some function arguments to use function typedefs in general.h so
+ the prototypes can be checked. The only use of Function and VFunction
+ now is for unwind-protects.
+
+f. More const changes to function arguments and appropriate variables.
+
+g. Changed the mail checking support to handle `maildir'-style mail
+ directories.
+
+h. Augmented the bash malloc to pass in the file and line number information
+ for each malloc, realloc, and free. This should result in better error
+ messages.
+
+i. The `old' gnu malloc is no longer a configuration option.
+
+j. Augmented the bash malloc with optional tracing and registering allocated
+ and freed memory.
+
+k. Prompt string decoding now saves and restores the value of $? when it
+ expands the prompt string, so command substitutions don't change $?.
+
+i. Array indices are now `long', since shell arithmetic is performed as long,
+ and the internal arrayind_t type is used consistently.
+
+j. Some more `unsigned char *' fixes from Paul Eggert.
+
+k. Fixed a bad call to builtin_error that could cause core dumps when making
+ local variables.
+
+l. `return' may no longer be used to terminate a `select' command, for
+ compatibility with ksh.
+
+m. Changed code that reads octal numbers to do a better job of detecting
+ overflows.
+
+n. The time formatting code no longer uses absolute indices into a buffer,
+ because the buffer size changes depending on the size of a `time_t'.
+
+o. `umask' now prints four digits when printing in octal mode, for
+ compatibility with other shells.
+
+p. Lots of changes to the `printf' builtin from Paul Eggert: it handles `L'
+ formats and long doubles better, and internal functions have been
+ simpified where appropriate.
+
+q. Some `time_t' fixes for machines were a time_t is bigger than a long.
+
+r. Replaced some bash-specific autoconf macros with standard equivalents.
+
+s. Improvmed the code that constructs temporary filenames to make the
+ generated names a bit more random.
+
+t. Added code that checks for ascii before calling any of the is* ctype
+ functions.
+
+u. Changed some places where a `char' was used as an array subscript to use
+ `unsigned char', since a `char' can be negative if it's signed by default.
+
+v. Lots of changes to the `ulimit' builtin from Paul Eggert to add support
+ for the new POSIX-200x RLIM_SAVED_CUR and RLIM_SAVED_MAX values and
+ simplify the code.
+
+w. `ulimit' now prints the description of a resource in any error message
+ relating to fetching or setting that resource's limits.
+
+x. The `snprintf' replacement now computes maximum values at compile
+ time rather than using huge constants for things like long long.
+
+y. Interactive shells now ignore `set -n'.
+
+z. Changed the malloc bookkeeping information so that it's now 8 bytes
+ instead of 12 on most 32-bit machines (saving 4 bytes per allocation),
+ restoring 8-byte alignment.
+
+aa. The malloc error reporting code now attempts to print the file and line
+ number of the call that caused the error.
+
+bb. Changed the redirection error reporting code to catch EBADF errors and
+ report the file descriptor number rather than the file being redirected
+ to or from (e.g., things like `exec 4242<x' where 4242 is an out-of-range
+ file descriptor).
+
+cc. `printf', `echo -e', and the $'...' code now process only two hex digits
+ after a `\x' escape sequence for compatibility with other shells, and
+ the documentation was changed to note that the octal and hex escape
+ sequences result in an eight-bit value rather than strict ASCII.
+
+2. Changes to Readline
+
+a. The completion code now attempts to do a better job of preserving the
+ case of the word the user typed if ignoring case in completions.
+
+b. Readline defaults to not echoing the input and lets the terminal
+ initialization code enable echoing if there is a controlling terminal.
+
+c. The key binding code now processes only two hex digits after a `\x'
+ escape sequence, and the documentation was changed to note that the
+ octal and hex escape sequences result in an eight-bit value rather
+ than strict ASCII.
+
+3. New Features in Bash
+
+a. The builtin `ulimit' now takes two new non-numeric arguments: `hard',
+ meaning the current hard limit, and `soft', meaning the current soft
+ limit, in addition to `unlimited'
+
+b. `ulimit' now prints the option letter associated with a particular
+ resource when printing more than one limit.
+
+c. `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is
+ one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively.
+
+4. New Features in Readline
+
+a. New bindable variable `history-preserve-point'. If set, the history
+ code attempts to place the user at the same location on each history
+ line retrived with previous-history or next-history.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05a-alpha1,
+and the previous version, bash-2.05-release.
+
+1. Changes to Bash
+
+a. Better checks in the redirection code for write errors.
+
+b. bashbug now uses $TMPDIR, defaulting to /tmp, and uses mktemp(1) more
+ portably.
+
+c. System-specific configuration changes for: Interix, OpenBSD, FreeBSD,
+ MacOS X.
+
+d. Some more `const' cleanups through the code.
+
+e. Fixed a typo in the /dev/fd redirection code, better checks for valid
+ numeric fds in /dev/fd.
+
+f. Fixed many parts of the shell to handle integer overflow more gracefully
+ and to do more stringent checks for valid numbers.
+
+g. Fixed mksignames to include config.h.
+
+h. Fixed an uninitialized variable problem that could cause the shell to core
+ dump when replacing characters in a string.
+
+i. New mechanism for updating the patch level when official patches are
+ released (patchlevel.h).
+
+j. configure.in changed to no longer require external files _distribution and
+ _patchlevel.
+
+k. Fixed non-interactive shell initialization problem when bash started as
+ `bash -i filename'.
+
+l. Fixed printf builtin conversion error handling to be POSIX.2-conformant.
+
+m. autoconf-2.52 is now used to build configure; autoconf-2.50 or newer is
+ required. Some of the bash-specific macros were removed, since they are
+ now standard.
+
+n. Startup files and files read with source or `.' are no longer required to
+ be regular files.
+
+o. Fixed core dump in builtin printf when user-supplied precision or field
+ width is 0.
+
+p. Fixed builtin printf to treat a negative field width as a positive field
+ width with left-justification.
+
+r. New unwind-protect implementation from Paul Eggert.
+
+s. Fixed an inadvertently-unclosed comment in the bash completion code that
+ caused programmable completions to not add trailing slashes or spaces to
+ completions.
+
+t. Fixed the process substitution code to cope better when stdin is closed.
+
+v. Fixes, mostly from Paul Eggert, for a few possible buffer overflows in
+ the shell.
+
+w. Fixes from Paul Eggert to avoid most of the type casts in the shell code,
+ and use more appropriate types for a number of variables.
+
+x. Command substition no longer inherits the DEBUG trap.
+
+y. Some fixes to the process substition code on machines without /dev/fd so
+ that named pipes are not removed inappropriately.
+
+z. The loadable `getconf' builtin is now much more complete, and will become
+ part of the shell in the future.
+
+aa. The select command no longer terminates on a `return', so it can be used
+ to return from an enclosing function (as ksh does it).
+
+bb. Fixed the extended pattern matching code to behave better when presented
+ with incorrectly-formed patterns.
+
+cc. Some changes were made with the intent of making cross-compilation easier.
+
+dd. The network code (/dev/tcp and /dev/udp redirections) uses getaddrinfo(3)
+ if it's available, which adds support for IPv6.
+
+ee. Subshells of login shells no longer source ~/.bash_logout when they exit.
+
+ff. Fixes so that subshells don't exit inappropriately if the -e option has
+ been set.
+
+gg. Restricted shells no longer allow functions to be exported.
+
+hh. Changes to the pattern matching code so extended pattern matching works
+ on systems with deficient shared library implementations, like MacOS X.
+
+ii. Better error messages when a script with a leading `#!interp' fails
+ to execute because of problems with `interp'.
+
+jj. Fixed `compgen' to handle the `-o default' option better.
+
+kk. Fixed the job control code to force an asynchronous process's standard
+ input to /dev/null only if job control is not active.
+
+ll. Fixed a possible infinite recursion problem when `fc ""=abc' (a null
+ pattern) is used to re-execute a previous command.
+
+mm. Fixed `declare [-a] var=value' to assign VALUE to element 0 if VAR is an
+ array variable. Similarly for `declare [-a] var[N]=value'. This is like
+ ksh93.
+
+nn. Fixed a bug that caused `read -a aname' to work even if ANAME had been
+ declared readonly.
+
+oo. Fixed a possible integer overflow problem when constructing names for
+ temporary files.
+
+2. New Features in Bash
+
+a. Added support for DESTDIR installation root prefix, so you can do a
+ `make install DESTDIR=bash-root' and do easier binary packaging.
+
+b. Added support for builtin printf "'" flag character as per latest POSIX
+ drafts.
+
+c. Support for POSIX.2 printf(1) length specifiers `j', `t', and `z' (from
+ ISO C99).
+
+d. New autoconf macro, RL_LIB_READLINE_VERSION, for use by other applications
+ (bash doesn't use very much of what it returns).
+
+e. `set [-+]o nolog' is recognized as required by the latest POSIX drafts,
+ but ignored.
+
+f. New read-only `shopt' option: login_shell. Set to non-zero value if the
+ shell is a login shell.
+
+g. New `\A' prompt string escape sequence; expands to time in 24 HH:MM format.
+
+h. New `-A group/-g' option to complete and compgen; does group name
+ completion.
+
+i. New `-t' option to `hash' to list hash values for each filename argument.
+
+j. New [-+]O invocation option to set and unset `shopt' options at startup.
+
+k. configure's `--with-installed-readline' option now takes an optional
+ `=PATH' suffix to set the root of the tree where readline is installed
+ to PATH.
+
+l. The ksh-like `ERR' trap has been added. The `ERR' trap will be run
+ whenever the shell would have exited if the -e option were enabled.
+ It is not inherited by shell functions.
+
+m. `readonly', `export', and `declare' now print variables which have been
+ given attributes but not set by assigning a value as just a command and
+ a variable name (like `export foo') when listing, as the latest POSIX
+ drafts require.
+
+n. `bashbug' now requires that the subject be changed from the default.
+
+o. configure has a new `--enable-largefile' option, like other GNU utilities.
+
+p. `for' loops now allow empty word lists after `in', like the latest POSIX
+ drafts require.
+
+3. Changes to Readline
+
+a. More `const' and type casting fixes.
+
+b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
+ overflow problems.
+
+c. The completion code no longer appends a `/' or ` ' to a match when
+ completing a symbolic link that resolves to a directory name, unless
+ the match does not add anything to the word being completed. This
+ means that a tab will complete the word up to the full name, but not
+ add anything, and a subsequent tab will add a slash.
+
+d. Fixed a trivial typo that made the vi-mode `dT' command not work.
+
+e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
+
+f. Fixed the tty code so that ^V works more than once.
+
+g. Changed the use of __P((...)) for function prototypes to PARAMS((...))
+ because the use of __P in typedefs conflicted g++ and glibc.
+
+4. New Features in Readline
+
+a. Added extern declaration for rl_get_termcap to readline.h, making it a
+ public function (it was always there, just not in readline.h).
+
+b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
+ RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d. New bindable boolean readline variable: match-hidden-files. Controls
+ completion of files beginning with a `.' (on Unix). Enabled by default.
+
+e. The history expansion code now allows any character to terminate a
+ `:first-' modifier, like csh.
+
+f. The incremental search code remembers the last search string and uses
+ it if ^R^R is typed without a search string.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-release,
+and the previous version, bash-2.05-beta2.
+
+1. Changes to Bash
+
+a. Make sure we note that the first line of a multi-line command was not
+ saved in the history if the tests for HISTCONTROL succeed, but the
+ HISTIGNORE check fails.
+
+b. Fixed a bug in the pattern matching code that caused `[' to be treated
+ as a special character inside a `[...]' bracket expression.
+
+c. Fixed a bug in the pattern matching code that caused `]' to terminate
+ a bracket expression even if it was the first character after the `['
+ (or a leading `!' or `^').
+
+d. Made a small change to report a more user-friendly error message if
+ execve(2) fails because of an error with the interpreter in a script
+ with a leading `#! interpreter'.
+
+e. If the OS does not support an exec(2) magic number of `#!', make sure we
+ have a non-null interpreter name before attempting to execute it.
+
+f. Fixed a bug that caused the shell process to end up in a different
+ process group than the controlling terminal if a job-control shell was
+ run with `exec' in the startup files.
+
+g. When started in POSIX mode, either by `bash --posix', `bash -o posix', or
+ `sh', $SHELLOPTS includes `posix' and POSIXLY_CORRECT is set.
+
+h. Fixed a problem that caused the `\W' prompt string escape sequence to
+ expand to nothing when $PWD was `//'.
+
+i. The `bashbug' shell script no longer uses $(...) command substitution.
+
+j. When `set' is invoked without options in POSIX mode, it no longer prints
+ the names and definitions of shell functions.
+
+2. Changes to Readline
+
+a. rl_set_paren_blink_timeout() is now documented.
+
+b. Corrected history.3 man page: `$' is not in the default value of
+ history_word_delimiters.
+
+c. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
+ value, rl_read_key() now immediately returns '\n' (which is assumed to
+ be bound to accept-line).
+
+3. New Features in Bash
+
+a. The `>&word' redirection now works in POSIX mode as it does by default,
+ since POSIX.2 leaves it unspecified.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-beta2,
+and the previous version, bash-2.05-beta1.
+
+1. Changes to Bash
+
+a. Fixed a bug in the arithmetic evaluation code so that a^=b is supported.
+
+b. Fixed startup so posixly_correct is retained across subshells begun to
+ execute scripts without a leading `#!'.
+
+c. Fixed a bug that caused $(< file) to not work in a (...) subshell.
+
+d. Added config support for Linux running on the IBM S390.
+
+e. Fixed a bug that caused bash to get its input pointer out of sync when
+ reading commands through a pipe and running a command with standard
+ input redirected from a file.
+
+f. Made a change so that command completion now makes about half as many
+ stat(2) calls when searching the $PATH.
+
+g. Fixed a bug that caused variable assignments preceding `return' to not
+ be propagated to the shell environment in POSIX mode.
+
+h. Fixed a bug with ${parameter[:]?word} -- tilde expansion was not performed
+ on `word'.
+
+i. In POSIX mode, `break' and `continue' do not complain and return success
+ if called when the shell is not executing a loop.
+
+j. Fixed `bash -o posix' to work the same as `bash --posix'.
+
+k. Fixed a bug where variable assignments preceding `eval' or `source/.'
+ would not show up in the environment exported to subshells run by the
+ commands.
+
+l. In POSIX mode, shells started to execute command substitutions inherit
+ the value of the `-e' option from their parent shell.
+
+m. In POSIX mode, aliases are expanded even in non-interactive shells.
+
+n. Changed some of the job control messages to display the text required by
+ POSIX.2 when the shell is in POSIX mode.
+
+o. Fixed a bug in `test' that caused it to occasionally return incorrect
+ results when non-numeric arguments were supplied to `-t'.
+
+2. Changes to Readline
+
+a. Some changes were made to avoid gcc warnings with -Wall.
+
+b. rl_get_keymap_by_name now finds keymaps case-insensitively, so
+ `set keymap EMACS' works.
+
+c. The history file writing and truncation functions now return a useful
+ status on error.
+
+d. Fixed a bug that could cause applications to dereference a NULL pointer
+ if a NULL second argument was passed to history_expand().
+
+3. New Features in Bash
+
+a. doc/readline.3 has been moved to the readline distribution.
+
+4. New Features in Readline
+
+a. New function, rl_get_screen_size (int *rows, int *columns), returns
+ readline's idea of the screen dimensions.
+
+b. The timeout in rl_gather_tyi (readline keyboard input polling function)
+ is now settable via a function (rl_set_keyboard_input_timeout()).
+
+c. Renamed the max_input_history variable to history_max_entries; the old
+ variable is maintained for backwards compatibility.
+
+d. The list of characters that separate words for the history tokenizer is
+ now settable with a variable: history_word_delimiters. The default
+ value is as before.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-beta1,
+and the previous version, bash-2.05-alpha1.
+
+1. Changes to Bash
+
+a. Changes to allow shared library and object building on the GNU Hurd.
+
+b. Fixes to the way exported functions are placed into the environment and
+ cached.
+
+c. The globbing library once again respects locales when processing ranges
+ in bracket expressions while doing pattern matching.
+
+d. System-specific configuration changes for: Tru 64, Interix
+
+e. Bashbug now uses /usr/bin/editor as one of the editing alternatives, and
+ will use mktemp(1) or tempfile(1), if present, for temporary file creation.
+
+f. Bash no longer performs a binary file check on a script argument that's
+ really a tty (like /dev/fd/0 or /dev/stdin).
+
+g. Fixed a bug in the execution of shell scripts that caused the effects of
+ $BASH_ENV to be undone in some cases.
+
+h. Fixed several bugs that made `bash [-i] /dev/stdin' not work correctly.
+
+i. Several changes to the job control code to avoid some signal state
+ manipulation.
+
+j. The Bash malloc no longer blocks signals as often, which should make it
+ faster.
+
+k. Fixed a parsing bug that did not allow backslash to escape a single quote
+ inside a $'...' construct.
+
+l. Fixed a bug that caused things like ${var:=$'value'} to be parsed
+ incorrectly. This showed up in newer versions of autoconf.
+
+m. Fixed a bug in the bash-specific readline initialization that caused
+ key bindings to bash-specific function names appearing in .inputrc to
+ not be honored.
+
+n. Bash now sets the file descriptor it uses to save the file descriptor
+ opened on a shell script to close on exec.
+
+o. Fixed a bug in the prompt string decoding that caused it to misbehave
+ when presented an octal sequence of fewer than three characters.
+
+p. Fixed the `test' builtin to return an error if `[' is supplied a single
+ argument that is not `]'.
+
+q. Fixed a bug that caused subshells started to run executable shell scripts
+ without a leading `#!' to incorrectly inherit an argument list preceding
+ a shell builtin (like such a script called from a script sourced with `.',
+ where there were variable assignments preceding the `.' command)
+
+r. Fixed a bug that caused changes to variables supplied in an assignment
+ statement preceding a shell builtin to not be honored (like a script
+ run with `.').
+
+s. HOSTTYPE, OSTYPE, and MACHTYPE are set only if they do not have values
+ when the shell is started.
+
+t. Fixed a bug that caused SIGINT to kill shell scripts after the script
+ called `wait'.
+
+u. The `fc' builtin now tries to create its temporary files in the directory
+ named by $TMPDIR.
+
+v. Bash no longer calls any Readline functions or uses any Readline variables
+ not declared in readline.h.
+
+w. Fixed a bug that caused some substitutions involving $@ to not be split
+ correctly, especially expansions of the form ${paramterOPword}.
+
+x. SSH2_CLIENT is now treated like SSH_CLIENT and not auto-exported if it
+ appears in the initial environment.
+
+y. Fixed a couple of problems with shell scripts without a leading `#!'
+ being executed out of shell functions that could cause core dumps if
+ such a script attempted to execute `return'.
+
+z. Fixed a problem with the `-nt' and `-ot' binary operators for the
+ `test/[' builtin and the `[[' conditional command that caused wrong
+ return values if one of the file arguments did not exist.
+
+aa. Fixed a bug that caused non-interactive shells which had previously
+ executed `shopt -s expand_aliases' to fail to expand aliases in a
+ command like `(command) &'.
+
+2. Changes to Readline
+
+a. Changes to make most (but not yet all -- there is still crlf()) of the
+ exported readline functions declared in readline.h have an rl_ prefix.
+
+b. More `const' changes in function arguments, mostly for completion
+ functions.
+
+c. Fixed a bug in rl_forward that could cause the point to be set to before
+ the beginning of the line in vi mode.
+
+d. Fixed a bug in the callback read-char interface to make it work when a
+ readline function pushes some input onto the input stream with
+ rl_execute_next (like the incremental search functions).
+
+e. Fixed a file descriptor leak in the history file manipulation code that
+ was tripped when attempting to truncate a non-regular file (like
+ /dev/null).
+
+f. Some existing variables are now documented and part of the public
+ interface (declared in readline.h): rl_explict_arg, rl_numeric_arg,
+ rl_editing_mode, rl_last_func.
+
+g. Renamed rltty_set_default_bindings to rl_tty_set_default_bindings and
+ crlf to rl_crlf, so there are no public functions declared in readline.h
+ without an `rl_' prefix. The old functions still exist for backwards
+ compatibility.
+
+3. New Features in Bash
+
+a. A new loadable builtin, realpath, which canonicalizes and expands symlinks
+ in pathname arguments.
+
+b. When `set' is called without options, it prints function defintions in a
+ way that allows them to be reused as input. This affects `declare' and
+ `declare -p' as well.
+
+4. New Features in Readline
+
+a. New application-callable function rl_set_prompt(const char *prompt):
+ expands its prompt string argument and sets rl_prompt to the result.
+
+b. New application-callable function rl_set_screen_size(int rows, int cols):
+ public method for applications to set readline's idea of the screen
+ dimensions.
+
+c. The history example program (examples/histexamp.c) is now built as one
+ of the examples.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.05-alpha1,
+and the previous version, bash-2.04-release.
+
+1. Changes to Bash
+
+a. A fix was made to allow newlines in compond array assignments.
+
+b. configure now checks for real-time signals with unusable values.
+
+c. Interactive shells no longer exit if a substitution fails because of an
+ unset variable within a sourced file.
+
+d. Fixed a problem with incorrect matching of extended glob patterns when
+ doing pattern substitution.
+
+e. `{' is now quoted by the completion code when it appears in a filename.
+
+f. Fixed an error in pattern matching that caused the matcher to not
+ correctly skip the rest of a bracket expression after a character
+ matched.
+
+g. Fixed a bug in the IFS word splitting code to make a non-whitespace IFS
+ character preceded by IFS whitespace part of the current delimiter rather
+ than generating a separate field.
+
+h. The {!prefix@} expansion now generates separate words, analogous to $@,
+ when double-quoted.
+
+i. Command substitution now ignores NUL bytes in the command output, and the
+ parser ignores them on input.
+
+j. A fix was made to the job control code to prevent hanging processes when
+ the shell thinks background processes are running but the kernel returns
+ -1/ECHILD from waitpid().
+
+k. `pwd' now prints an error message if the write fails when displaying the
+ current directory.
+
+l. When in POSIX mode, the shell prints trap dispostions without a leading
+ `SIG' in the signal specification.
+
+m. Fixed a parser bug that caused the current command's line count to be
+ messed up by a compound array assignment.
+
+n. Fixed a bug in the unwind-protect code that caused bad behavior on machines
+ where ints and pointers are not the same size.
+
+o. System-specific configure changes for: MacOS X.
+
+p. Changes for Cygwin to translate \r\n and \r to \n and to set file
+ descriptors used for reading input to text mode in various places.
+
+q. Fixed a bug that caused `!' to occasionally not be honored when in
+ a (...) subshell.
+
+r. Bash no longer assumes that getcwd() will return any useful error message
+ in the buffer passed as an argument if the call fails.
+
+s. The `source', `.', and `fc' builtins no longer check whether a file is
+ binary before reading commands from it.
+
+t. Subshells no longer turn off job control when they exit, since that
+ sometimes resulted in the terminal being reset to the wrong process
+ group.
+
+u. The history code no longer tries to save the second and subsequent lines
+ of a multi-line command if the first line was not saved.
+
+v. The history saving code now does a better job of saving blank lines in a
+ multi-line command.
+
+w. Removed a `feature' that made `ulimit' silently translate `unlimited' to
+ the current hard limit, which obscured some kernel error returns.
+
+x. Fixed the grammar so that `}' is recognized as a reserved word after
+ another reserved word, rather than requiring a `;' or newline. This
+ means that constructs like
+
+ { { echo a b c ; } }
+
+ work as expected.
+
+y. Conditional commands ([[...]]) now perform tilde expansion on their
+ arguments.
+
+z. Noted in the documentation that `set -a' will cause functions to be
+ exported if they are defined after `set -a' is executed.
+
+aa. When an interactive login shell starts, if $PWD and $HOME refer to the
+ same directory but are not the same string, $PWD is set to $HOME.
+
+bb. Fixed `printf' to handle invalid floating point numbers better.
+
+cc. Temporary files are now created with random filenames, to improve security.
+
+dd. The readline initialization code now binds the custom bash functions and
+ key bindings after the readline defaults are set up.
+
+ee. Fixed the `source' builtin to no longer overwrite a shell function's
+ argument list, even if the sourced file changes the positional parameters.
+
+ff. A bug fix was made in the expansion of `$*' in contexts where it should
+ not be split, like assignment statements.
+
+gg. Fixed a bug in the parameter substring expansion to handle conditional
+ arithmetic expressions ( exp ? val1 : val2 ) without cutting the expression
+ off at the wrong `:'.
+
+hh. The `<>' redirection is no longer subject to the current setting of
+ `noclobber', as POSIX.2 specifies.
+
+ii. Fixed a bug in the conditional command parsing code that caused expressions
+ in parentheses to occasionally be parsed incorrectly.
+
+jj. Fixed a bug in the ((...)) arithmetic command to allow do...done or
+ {...} to follow the )) without an intervening list terminator.
+
+kk. `printf' now treats `\E' the same as `\e' when performing backslash escape
+ expansion for the `%b' format specifier.
+
+ll. When in POSIX mode, the shell no longer searches the current directory for
+ a file to be sourced with `.' or `source' if `.' is not in $PATH.
+
+mm. Interactive comments are no longer turned off when POSIX mode is disabled.
+
+nn. The UID, EUID, HOSTNAME variables are not set if they are in the shell's
+ environment when it starts up.
+
+oo. Fixed a bug in the `command' builtin so the effect of a command like
+ `command exec 4<file' is as if the `command' had been omitted.
+
+pp. ${foo[@]} and ${foo[*]} now work as in ksh93 if `foo' is not an array
+ variable.
+
+qq. ${#foo[X]}, where X is 0, @, or *, now work as in ksh93 if `foo' is not
+ an array variable.
+
+rr. The shell's idea of an absolute pathname now takes into account a
+ possible drive specification on Cygwin and other Windows systems.
+
+ss. Fixed a bug which caused incorrect parsing of some multi-character
+ constructs if they were split across input lines with backslash-newline
+ line continuation.
+
+tt. Fixed a bug that caused restricted shell mode to be set inappropriately
+ when trying to execute a shell script without a leading `#!'.
+
+uu. Shell function definitions no longer require that the body be a group
+ command ( {...} ), as POSIX.2 requires.
+
+vv. The `cd' and `pwd' builtins now process symlinks in pathnames internally
+ and should require many fewer calls to getcwd().
+
+ww. Fixed a bug that caused a pipeline's process group to be set incorrectly
+ if one of the pipeline elements contained a command substitution.
+
+xx. Fixed a bug that caused core dumps when expanding the value of HISTIGNORE.
+
+yy. The output of `set' is now quoted using $'...' so invisible characters are
+ displayed as escape sequences.
+
+zz. Fixed the help text for `unset', since PATH and IFS may both be unset.
+
+aaa. The shell no longer puts directory names into the command hash table.
+
+bbb. Fixed a bug in `read' that caused it to occasionally free memory twice if
+ it was interrupted after reading a large amount of data.
+
+ccc. Assignment statements that attempt to assign values to readonly variables
+ now cause the command to return an error status.
+
+ddd. Fixed a bug that could cause incorrect output if a $(<file) construct was
+ interrupted.
+
+eee. GROUPS and FUNCNAME now return an error status when assignment is
+ attempted, but may be unset (in which case they lose their special
+ properties). In all respects except unsetting, they are readonly.
+
+fff. The string-to-integer conversion code now ignores trailing whitespace in
+ the string, even if strtol(3) does not.
+
+ggg. The tcsh magic-space function now does a better job of inserting the
+ space close to where the point was before the history expansion, rather
+ than just appending it.
+
+hhh. Fixed a bug which caused a file sourced from an interactive shell to
+ fill up the jobs table if it ran lots of jobs.
+
+iii. Fixed a bug in the parameter pattern substitution code to avoid infinite
+ recursion on zero-length matches.
+
+2. Changes to Readline
+
+a. When setting the terminal attributes on systems using `struct termio',
+ readline waits for output to drain before changing the attributes.
+
+b. A fix was made to the history word tokenization code to avoid attempts to
+ dereference a null pointer.
+
+c. Readline now defaults rl_terminal_name to $TERM if the calling application
+ has left it unset, and tries to initialize with the resultant value.
+
+d. Instead of calling (*rl_getc_function)() directly to get input in certain
+ places, readline now calls rl_read_key() consistently.
+
+e. Fixed a bug in the completion code that allowed a backslash to quote a
+ single quote inside a single-quoted string.
+
+f. rl_prompt is no longer assigned directly from the argument to readline(),
+ but uses memory allocated by readline. This allows constant strings to
+ be passed to readline without problems arising when the prompt processing
+ code wants to modify the string.
+
+g. Fixed a bug that caused non-interactive history searches to return the
+ wrong line when performing multiple searches backward for the same string.
+
+h. Many variables, function arguments, and function return values are now
+ declared `const' where appropriate, to improve behavior when linking with
+ C++ code.
+
+i. The control character detection code now works better on systems where
+ `char' is unsigned by default.
+
+j. The vi-mode numeric argument is now capped at 999999, just like emacs mode.
+
+k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been
+ replaced with a set of specific prototyped typedefs, though they are
+ still in the readline header files for backwards compatibility.
+
+m. Nearly all of the (undocumented) internal global variables in the library
+ now have an _rl_ prefix -- there were a number that did not, like
+ screenheight, screenwidth, alphabetic, etc.
+
+n. The ding() convenience function has been renamed to rl_ding(), though the
+ old function is still defined for backwards compatibility.
+
+o. The completion convenience functions filename_completion_function,
+ username_completion_function, and completion_matches now have an rl_
+ prefix, though the old names are still defined for backwards compatibility.
+
+p. The functions shared by readline and bash (linkage is satisfied from bash
+ when compiling with bash, and internally otherwise) now have an sh_ prefix.
+
+q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so
+ that the `soname' contains only the major version number rather than the
+ major and minor numbers.
+
+r. Fixed a redisplay bug that occurred when the prompt spanned more than one
+ physical line and contained invisible characters.
+
+3. New Features in Bash
+
+a. Added a new `--init-file' invocation argument as a synonym for `--rcfile',
+ per the new GNU coding standards.
+
+b. The /dev/tcp and /dev/udp redirections now accept service names as well as
+ port numbers.
+
+c. `complete' and `compgen' now take a `-o value' option, which controls some
+ of the aspects of that compspec. Valid values are:
+
+ default - perform bash default completion if programmable
+ completion produces no matches
+ dirnames - perform directory name completion if programmable
+ completion produces no matches
+ filenames - tell readline that the compspec produces filenames,
+ so it can do things like append slashes to
+ directory names and suppress trailing spaces
+
+4. New Features in Readline
+
+a. The blink timeout for paren matching is now settable by applications.
+
+b. _rl_executing_macro has been renamed to rl_executing_macro, which means
+ it's now part of the public interface.
+
+c. Readline has a new variable, rl_readline_state, which is a bitmap that
+ encapsulates the current state of the library; intended for use by
+ callbacks and hook functions.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-release,
+and the previous version, bash-2.04-beta5.
+
+1. Changes to Bash
+
+a. Better compile-time and configure-time checks for the necessity of
+ inet_aton().
+
+b. A bug was fixed in the expansion of "${@:-}" when there are positional
+ parameters.
+
+c. A typo was fixed in the output of `complete'.
+
+d. The matches generated for a word by the `-W' argument to complete and
+ compgen are now matched against the word being completed, and only
+ matches are returned as the result.
+
+e. Some fixes were made for systems which do not restart read(2) when a
+ signal caught by bash is received.
+
+f. A bug was fixed which caused the umask to be set to 0 when an invalid
+ symbolic mode mask was parsed.
+
+g. Fixed a bug that could cause a core dump if a SIGCHLD was received while
+ performing an assignment statement using command substitution.
+
+h. Changed the word splitting function for programmable completion so cases
+ in which the cursor is between words are handled a bit better.
+
+2. Changes to Readline
+
+a. rl_funmap_names() is now documented.
+
+3. New Features in Bash
+
+a. The LC_NUMERIC variable is now treated specially, and used to set the
+ LC_NUMERIC locale category for number formatting, e.g., when `printf'
+ displays floating-point numbers.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.04-beta5,
+and the previous version, bash-2.04-beta4.
+
+1. Changes to Bash
+
+a. A couple of changes were made to the Makefiles for easier building on
+ non-Unix systems.
+
+b. Fixed a bug where the current prompt would be set to $PS2 at startup.
+
+c. The shell script that tests an already-installed version was changed to
+ remove the directory it created its test programs in at exit.
+
+d. Several changes were made to the code that tokenizes an input line for
+ the programmable completion code. Shell metacharacters will now appear
+ as individual words in the word list passed to the completion functions.

+
+f. A bug was fixed in the ulimit builtin for systems not using getrlimit().
+
+g. The execution code now propagates the correct exit status back to the rest
+ of the code if the return value of a subshell command was being inverted.
+ Some new test cases for inverting return values with the `!' reserved
+ word have been added.
+
+h. Negative exponents in the arithmetic evaluation of v**e now return an
+ evaluation error.
+
+i. A bug that caused bash to check the wrong process in a pipeline for

+
+p. The prompt string decoding code now backslash-quotes only characters that
+ are special within double quotes when expanding the \w and \W escape
+ sequences.

+and the previous version, bash-2.04-alpha1.
+
+1. Changes to Bash

+ `compgen -C xyz' gracefully.
+
+e. The shell no longer modifies the signal handler for SIGPROF, allowing
+ profiling again on certain systems.
+
+f. The shell checks for a new window size, if the user has requested it,
+ after a process exits due to a signal.
+
+g. Fixed a bug with variables with null values in a program's temporary

+
+j. The code that caches export strings from the initial environment now
+ duplicates the string rather than just pointing into the environment.
+
+k. The filename completion quoting code now uses single quotes by default
+ if the filename being completed contains newlines, since \<newline>
+ has a special meaning to the parser.
+
+l. Bash now uses typedefs bits32_t and u_bits32_t instead of int32_t and
+ u_int32_t, respectively to avoid conflicts on certain Unix versions.
+

+
+n. Fixed a problem with hostname-to-ip-address translation in the
+ /dev/(tcp|udp)/hostname/port redirection code.
+
+o. The texinfo manual has been reorganized slightly.
+
+p. Filename generation (globbing) range comparisons in bracket expressions
+ no longer use strcoll(3) even if it is available, since it has unwanted
+ effects in certain locales.
+
+q. Fixed a cosmetic problem in the source that caused the shell to not
+ compile if DPAREN_ARITHMETIC was not defined but ARITH_FOR_COMMAND was.
+
+r. Fixed a bug in the here-document code tripped when the file descriptor
+ opened to the file containing the text of the here document was the
+ same as a redirector specified by the user.
+
+s. Fixed a bug where the INVERT_RETURN flag was not being set for `pipeline'
+ in `time ! pipeline'.
+
+t. Fixed a bug with the `wait' builtin which manifested itself when an
+ interrupt was received while the shell was waiting for asynchronous
+ processes in a shell script.
+
+u. Fixed the DEBUG trap code so that it has the correct value of $?.
+
+v. Fixed a bug in the parameter pattern substitution code that could cause
+ the shell to attempt to free unallocated memory if the pattern started
+ with `/' and an expansion error occurs.
+
+w. Fixed a bug in the positional parameter substring code that could
+ cause the shell to loop freeing freed memory.
+
+x. Fixed a bug in the positional parameter pattern substitution code so
+ that it correctly handles null replacement strings with a pattern
+ string prefixed with `%' or `#'.
+
+y. The shell no longer attempts to import functions from the environment if
+ started with `-n'.
+
+z. Fixed a bug that caused `return' in a command substitution executed in
+ a shell function to return from the function in a subshell and continue
+ execution.
+
+aa. `hash -p /pathname/with/slashes name' is no longer allowed when the shell
+ is restricted.

+ state.
+
+ee. `bashbug' now honors user headers in the mail message it sends.
+
+ff. A bug was fixed that caused the `:p' history modifier to not print the
+ history expansion if the `histverify' option was set.
+
+2. Changes to Readline
+
+a. Fixed a bug in the redisplay code for lines with more than 256 line
+ breaks.
+
+b. A bug was fixed which caused invisible character markers to not be
+ stripped from the prompt string if the terminal was in no-echo mode.
+
+c. Readline no longer tries to get the variables it needs for redisplay
+ from the termcap entry if the calling application has specified its
+ own redisplay function. Readline treats the terminal as `dumb' in
+ this case.
+
+d. Fixes to the SIGWINCH code so that a multiple-line prompt with escape
+ sequences is redrawn correctly.
+
+3. New Features in Bash
+
+a. `bashbug' now accepts `--help' and `--version' options.
+
+b. There is a new `xpg_echo' option to `shopt' that controls the behavior
+ of echo with respect to backslash-escaped characters at runtime.

+a. Fixed a bug that could cause core dumps when performing substring
+ expansion.
+
+b. Shared object configuration changes for: Solaris, OSF/1
+
+c. The POSIX_GLOB_LIBRARY code that uses the POSIX.2 globbing facilities
+ for pathname expansion now understands GLOBIGNORE.
+
+d. The code that implements `eval' was changed to save the value of the
+ current prompt, so an eval in a shell function called by the programmable
+ completion code will not change the prompt to $PS2.
+
+e. Restored the undocumented NON_INTERACTIVE_LOGIN_SHELLS #define to
+ config-top.h. If this is defined, all login shells will read the
+ startup files, not just interactive and non-interactive started with
+ the `--login' option.
+
+f. Fixed a bug that caused the expansion code to occasionally dump core if
+ IFS contained characters > 128.
+
+g. Fixed a problem with the grammar so that a newline is not required
+ after the `))' in the new-style arithmetic for statement; a semicolon
+ may be used as expected.
+
+h. Variable indirection may now reference the shell's special variables.
+
+i. The $'...' and $"..." constructs are now added to the history correctly
+ if they contain newlines and command-oriented history is enabled.

+ the history file on cygwin32.
+
+3. New Features in Bash

+
+b. configure has a new option, `--enable-progcomp', to compile in the
+ programmable completion features (enabled by default).
+
+c. `shopt' has a new option, `progcomp', to enable and disable programmable
+ completion at runtime.
+
+d. Unsetting HOSTFILE now clears the list of hostnames used for completion.
+
+4. New Features in Readline

+
+m. Improvements were made to the `read' builtin so that it makes many
+ fewer read(2) system calls.
+
+n. The expansion of $- will include `c' and `s' when those options are

+ simplified considerably and should work better now.
+
+x. Fixes to the non-job-control code in nojobs.c to make it POSIX.2-compliant
+ when a user attempts to retrieve the status of a terminated background
+ process.
+
+y. Fixes to the `printf' builtin so that it doesn't try to expand all
+ backslash escape sequences in the format string before parsing it for

+
+2. Changes to Readline
+

+ of rl_getc_function rather than calling rl_getc directly.
+
+3. New Features in Bash
+
+a. The history builtin has a `-d offset' option to delete the history entry
+ at position `offset'.
+
+b. The prompt expansion code has two new escape sequences: \j, the number of

+
+c. The `bind' builtin has a new `-x' option to bind key sequences to shell
+ commands.
+
+d. There is a new shell option, no_empty_command_completion, which, when

+
+e. The `help' builtin has a `-s' option to just print a builtin's usage
+ synopsys.
+
+f. There are several new arithmetic operators: id++, id-- (variable
+ post-increment/decrement), ++id, --id (variabl pre-increment/decrement),
+ expr1 , expr2 (comma operator).
+
+g. There is a new ksh-93 style arithmetic for command:
+ for ((expr1 ; expr2; expr3 )); do list; done
+
+h. The `read' builtin has a number of new options:
+ -t timeout only wait timeout seconds for input
+ -n nchars only read nchars from input instead of a full line
+ -d delim read until delim rather than newline

+
+i. The redirection code now handles several filenames specially:
+ /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or
+ not they are present in the file system.
+
+j. The redirection code now recognizes pathnames of the form
+ /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket
+ of the appropriate type to the specified port on the specified host.
+
+k. The ksh-93 ${!prefix*} expansion, which expands to the names of all
+ shell variables whose names start with prefix, has been implemented.
+
+l. There is a new dynamic variable, FUNCNAME, which expands to the name of
+ a currently-executing function. Assignments to FUNCNAME have no effect.
+
+m. The GROUPS variable is no longer readonly; assignments to it are silently
+ discarded. This means it can be unset.
+
+4. New Features in Readline
+
+a. Parentheses matching is now always compiled into readline, and enabled
+ or disabled when the value of the `blink-matching-paren' variable is

+ to occasionally have the wrong value for $!.
+
+2. Changes to Readline

+ following compound commands have a space separating them from the rest
+ of the command.
+
+h. The pathname canonicalization code was changed to produce fewer leading
+ `//' sequences, since those are interpreted as network file system
+ pathnames on some systems.
+
+i. A fix was made so that loops containing `eval' commands in commands passed
+ to `bash -c' would not exit prematurely.
+
+j. Some changes were made to the job reaping code when the shell is not
+ interactive, so the shell will retain exit statuses longer for examination
+ by `wait'.
+
+k. A fix was made so that `jobs | command' works again.
+
+l. The erroneous compound array assignment var=((...)) is now a syntax error.
+
+m. A change was made to the dynamic loading code in `enable' to support

+
+n. A fix was made to the globbing code so that extended globbing patterns
+ will correctly match `.' in a bracket expression.
+
+2. Changes to Readline
+
+a. A fix was made to the completion code in which a typo caused the wrong
+ value to be passed to the function that computed the longest common
+ prefix of the list of matches.
+
+b. The completion code now checks the value of rl_filename_completion_desired,
+ which is set by application-supplied completion functions to indicate
+ that filename completion is being performed, to decide whether or not to
+ call an application-supplied `ignore completions' function.
+
+3. New Features in Bash
+
+a. A change was made to the startup file code so that any shell begun with
+ the `--login' option, even non-interactive shells, will source the login
+ shell startup files.
+
+4. New Features in Readline

+a. A new variable, rl_erase_empty_line, which, if set by an application using
+ readline, will cause readline to erase, prompt and all, lines on which the
+ only thing typed was a newline.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.03-alpha,
+and the previous version, bash-2.02.1-release.

+ from the net.
+
+c. The configure tests that determine which native type is 32 bits were
+ changed to not require a compiled program.
+
+d. Fixed a bug in shell_execve that could cause memory to be freed twice
+ after a failed exec.
+
+e. The `printf' test uses `diff -a' if it's available to prevent confusion
+ due to the non-ascii output.
+
+f. Shared object configuration is now performed by a shell script,
+ support/shobj-conf, which generates values to be substituted into
+ makefiles by configure.
+
+g. Some changes were made to `ulimit' to avoid the use of RLIM_INVALID as a
+ return value.
+
+h. Changes were made to `ulimit' to work around HPUX 9.x's peculiar
+ handling of RLIMIT_FILESIZE.
+
+i. Some new loadable builtins were added: id, printenv, sync, whoami, push,
+ mkdir. `pushd', `popd', and `dirs' can now be built as regular or
+ loadable builtins from the same source file.
+
+j. Changes were made to `printf' to handle NUL bytes in the expanded format
+ string.
+
+k. The various `make clean' Makefile targets now descend into lib/sh.

+l. The `type' builtin was changed to use the internal `getopt' so that things
+ like `type -ap' work as expected.
+
+m. There is a new configuration option, --with-installed-readline, to link
+ bash with a locally-installed version of readline. Only readline version
+ 4.0 and later releases can support this. Shared and static libraries
+ are supported. The installed include files are used.
+
+n. There is a new autoconf macro used to find which basic type is 64 bits.
+
+o. Dynamic linking and loadable builtins should now work on SCO 3.2v5*,
+ AIX 4.2 with gcc, Unixware 7, and many other systems using gcc, where
+ the `-shared' options works correctly.
+
+p. A bug was fixed in the bash filename completion code that caused memory to
+ be freed twice if a directory name containing an unset variable was
+ completed and the -u option was set.
+
+q. The prompt expansion code now quotes the `$' in the `\$' expansion so it
+ is not processed by subsequent parameter expansion.
+
+r. Fixed a parsing bug that caused a single or double quote after a `$$' to
+ trigger ANSI C expansion or locale translation.
+
+s. Fixed a bug in the globbing code that caused quoted filenames containing
+ no globbing characters to sometimes be incorrectly expanded.
+
+t. Changes to the default prompt strings if prompt string decoding is not
+ compiled into the shell.

+u. Added `do', `then', `else', `{', and `(' to the list of keywords that may
+ precede the `time' reserved word.
+
+v. The shell may now be cross-built for BeOS as well as cygwin32.
+
+w. The conditional command execution code now treats `=' the same as `=='
+ for deciding when to perform pattern matching.
+
+x. The `-e' option no longer causes the shell to exit if a command exits
+ with a non-zero status while running the startup files.
+
+y. The `printf' builtin no longer dumps core if a modifier is supplied in
+ the format string without a conversion character (e.g. `%h').
+
+z. Array assignments of the form a=(...) no longer show up in the history
+ list.
+
+aa. The parser was fixed to obey the POSIX.2 rules for finding the closing
+ `}' in a ${...} expression.
+
+bb. The history file is now opened with mode 0600 rather than 0666, so bash
+ no longer relies on the user's umask being set appropriately.
+
+cc. Setting LANG no longer causes LC_ALL to be assigned a value; bash now
+ relies on proper behavior from the C library.
+
+dd. Minor changes were made to allow quoted variable expansions using
+ ${...} to be completed correctly if there is no closing `"'.
+
+ee. Changes were made to builtins/Makefile.in so that configuring the shell
+ with `--enable-profiling' works right and builtins/mkbuiltins is
+ generated.
+
+2. Changes to Readline
+
+a. The version number is now 4.0.
+
+b. There is no longer any #ifdef SHELL code in the source files.
+
+c. Some changes were made to the key binding code to fix memory leaks and
+ better support Win32 systems.
+
+d. Fixed a silly typo in the paren matching code -- it's microseconds, not
+ milliseconds.
+
+e. The readline library should be compilable by C++ compilers.
+
+f. The readline.h public header file now includes function prototypes for
+ all readline functions, and some changes were made to fix errors in the
+ source files uncovered by the use of prototypes.
+
+g. The maximum numeric argument is now clamped at 1000000.
+
+h. Fixes to rl_yank_last_arg to make it behave better.
+
+i. Fixed a bug in the display code that caused core dumps if the prompt
+ string length exceeded 1024 characters.
+
+j. The menu completion code was fixed to properly insert a single completion
+ if there is only one match.
+
+k. A bug was fixed that caused the display code to improperly display tabs
+ after newlines.
+
+3. New Features in Bash
+
+a. New `shopt' option, `restricted_shell', indicating whether or not the
+ shell was started in restricted mode, for use in startup files.
+
+b. Filename generation is now performed on the words between ( and ) in
+ array assignments (which it probably should have done all along).
+
+c. OLDPWD is now auto-exported, as POSIX.2 seems to require.
+
+d. ENV and BASH_ENV are read-only variables in a restricted shell.
+
+4. New Features in Readline
+
+a. Many changes to the signal handling:
+ o Readline now catches SIGQUIT and cleans up the tty before returning;
+ o A new variable, rl_catch_signals, is available to application writers
+ to indicate to readline whether or not it should install its own
+ signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+ SIGTTIN, and SIGTTOU;
+ o A new variable, rl_catch_sigwinch, is available to application
+ writers to indicate to readline whether or not it should install its
+ own signal handler for SIGWINCH, which will chain to the calling
+ applications's SIGWINCH handler, if one is installed;
+ o There is a new function, rl_free_line_state, for application signal
+ handlers to call to free up the state associated with the current
+ line after receiving a signal;
+ o There is a new function, rl_cleanup_after_signal, to clean up the
+ display and terminal state after receiving a signal;
+ o There is a new function, rl_reset_after_signal, to reinitialize the
+ terminal and display state after an application signal handler
+ returns and readline continues
+
+b. There is a new function, rl_resize_terminal, to reset readline's idea of
+ the screen size after a SIGWINCH.
+
+c. New public functions: rl_save_prompt and rl_restore_prompt. These were
+ previously private functions with a `_' prefix.
+
+d. New function hook: rl_pre_input_hook, called just before readline starts
+ reading input, after initialization.
+
+e. New function hook: rl_display_matches_hook, called when readline would
+ display the list of completion matches. The new function
+ rl_display_match_list is what readline uses internally, and is available
+ for use by application functions called via this hook.
+
+f. New bindable function, delete-char-or-list, like tcsh.

+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.02-alpha1,
+and the previous version, bash-2.01.1-release.

+
+a. OS-specific configuration changes for: BSD/OS 3.x, Minix 2.x,
+ Solaris 2.6, SINIX SVR4.
+
+b. Changes were made to the generated `info' files so that `install-info'
+ works correctly.

+
+f. The default sizes of some internal hash tables have been made smaller
+ to reduce the shell's memory footprint.
+
+g. The `((...))' arithmetic command is now executed directly instead of
+ being translated into `let "..."'.
+
+h. Fixes were made to the expansion code so that "$*", "$@", "${array[@]}",
+ and "${array[@]}" expand correctly when IFS does not contain a space
+ character, is unset, or is set to NULL.
+
+i. The indirect expansion code (${!var}) was changed so that the only
+ valid values of `var' are variable names, positional parameters, `#',
+ `@', and `*'.
+
+j. An arithmetic expression error in a $((...)) expansion now causes a
+ non-interactive shell running in posix mode to exit.
+
+k. Compound array assignment now splits the words within the parentheses
+ on shell metacharacters like the parser would before expansing them
+ and performing the assignment. This is for compatibility with ksh-93.
+
+l. The internal shell backslash-quoting code (used in the output of `set'
+ and completion) now quotes tildes if they appear at the start of the
+ string or after a `=' or `:'.

+p. The filename globbing code no longer requires read permission for a
+ directory when the filename to be matched does not contain any globbing
+ characters, as POSIX.2 specifies.
+
+q. A bug was fixed so that the job containing the last asynchronous
+ process is not removed from the job table until a `wait' is executed
+ for that process or another asynchronous process is started. This
+ satisfies a POSIX.2 requirement.
+
+r. A `select' bug was fixed so that a non-numeric user response is treated
+ the same as a numeric response that is out of range.
+
+s. The shell no longer parses the value of SHELLOPTS from the environment
+ if it is restricted, running setuid, or running in `privileged mode'.
+
+t. Fixes were made to enable large file support on systems such as
+ Solaris 2.6, where the size of a file may be larger than can be held
+ in an `int'.
+
+u. The filename hashing code was fixed to not add `./' to the beginning of
+ filenames which already begin with `./'.
+
+v. The configure script was changed so that the GNU termcap library is not

+w. HISTCONTROL and HISTIGNORE are no longer applied to the second and
+ subsequent lines of a multi-line command.
+
+x. A fix was made to `disown' so that it does a better job of catching
+ out-of-range jobs.

+y. Non-interactive shells no longer report the status of processes terminated
+ due to SIGINT, even if the standard output is a terminal.
+
+z. A bug that caused the output of `jobs' to have extra carriage returns
+ was fixed.
+
+aa. A bug that caused PIPESTATUS to not be set when builtins or shell
+ functions were executed in the foreground was fixed.
+
+bb. Bash now attempts to detect when it is being run by sshd, and treats
+ that case identically to being run by rshd.
+
+cc. A bug that caused `set -a' to export SHELLOPTS when one of the shell
+ options was changed was fixed.
+
+dd. The `kill' builtin now disallows empty or missing process id arguments
+ instead of treating them as identical to `0', which means the current
+ process.
+
+ee. `var=value declare -x var' now behaves identically to
+ `var=value export var'. Similarly for `var=value declare -r var' and
+ `var=value readonly var'.
+
+ff. A few memory leaks were fixed.
+
+gg. `alias' and `unalias' now print error messages when passed an argument
+ that is not an alias for printing or deletion, even when the shell is
+ not interactive, as POSIX.2 specifies.
+
+hh. `alias' and `alias -p' now return a status of 0 when no aliases are
+ defined, as POSIX.2 specifes.
+
+ii. `cd -' now prints the pathname of the new working directory if the shell
+ is interactive.
+
+jj. A fix was made so that the code that binds $PWD now copes with getcwd()
+ returning NULL.
+
+kk. `unset' now checks whether or not a function name it's trying to unset
+ is a valid shell identifier only when the shell is running in posix mode.
+
+ll. A change was made to the code that generates filenames for here documents
+ to make them less prone to name collisions.
+
+mm. The parser was changed so that `time' is recognized as a reserved word
+ only at the beginning of a pipeline.
+
+nn. The pathname canonicalization code was changed so that `//' is converted
+ into `/', but all other pathnames beginning with `//' are left alone, as
+ POSIX.2 specifies.
+
+oo. The `logout' builtin will no longer exit a non-interactive non-login
+ shell.
+
+2. Changes to Readline
+
+a. Fixed a problem in the readline test program rltest.c that caused a core
+ dump.
+
+b. The code that handles parser directives in inputrc files now displays
+ more error messages.
+
+c. The history expansion code was fixed so that the appearance of the
+ history comment character at the beginning of a word inhibits history
+ expansion for that word and the rest of the input line.
+
+3. New Features in Bash
+
+a. A new version of malloc, based on the older GNU malloc, that has many
+ changes, is more page-based, is more conservative with memory usage,
+ and does not `orphan' large blocks when they are freed.
+
+b. A new version of gmalloc, based on the old GLIBC malloc, with many
+ changes and range checking included by default.
+
+c. A new implementation of fnmatch(3) that includes full POSIX.2 Basic

+ symbols, equivalence classes, and support for case-insensitive pattern
+ matching.

+ implemented, controlled by a new `shopt' option, `extglob'.
+
+e. There is a new ksh-like `[[' compound command, which implements
+ extended `test' functionality.
+
+f. There is a new `printf' builtin, implemented according to the POSIX.2
+ specification.
+
+g. There is a new feature for command substitution: $(< filename) now expands
+ to the contents of `filename', with any trailing newlines removed
+ (equivalent to $(cat filename)).
+
+h. There are new tilde prefixes which expand to directories from the
+ directory stack.
+
+i. There is a new `**' arithmetic operator to do exponentiation.
+
+j. There are new configuration options to control how bash is linked:
+ `--enable-profiling', to allow bash to be profiled with gprof, and
+ `--enable-static-link', to allow bash to be linked statically.
+
+k. There is a new configuration option, `--enable-cond-command', which
+ controls whether or not the `[[' command is included. It is on by
+ default.
+
+l. There is a new configuration option, `--enable-extended-glob', which
+ controls whether or not the ksh extended globbing feature is included.
+ It is enabled by default.
+
+m. There is a new configuration #define in config.h.top that, when enabled,
+ will cause all login shells to source /etc/profile and one of the user-
+ specific login shell startup files, whether or not the shell is
+ interactive.
+
+n. There is a new invocation option, `--dump-po-strings', to dump
+ a shell script's translatable strings ($"...") in GNU `po' format.
+
+o. There is a new `shopt' option, `nocaseglob', to enable case-insensitive
+ pattern matching when globbing filenames and using the `case' construct.
+
+p. There is a new `shopt' option, `huponexit', which, when enabled, causes
+ the shell to send SIGHUP to all jobs when an interactive login shell
+ exits.
+
+q. `bind' has a new `-u' option, which takes a readline function name as an
+ argument and unbinds all key sequences bound to that function in a
+ specified keymap.
+
+r. `disown' now has `-a' and `-r' options, to limit operation to all jobs
+ and running jobs, respectively.
+
+s. The `shopt' `-p' option now causes output to be displayed in a reusable
+ format.
+
+t. `test' has a new `-N' option, which returns true if the filename argument
+ has been modified since it was last accessed.
+
+u. `umask' now has a `-p' option to print output in a reusable format.
+
+v. A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...'
+ translation code. It expands to the character whose ascii code is NNN
+ in hexadecimal.
+
+w. The prompt string expansion code has a new `\r' escape sequence.
+
+x. The shell may now be cross-compiled for the CYGWIN32 environment on
+ a Unix machine.
+
+4. New Features in Readline
+
+a. There is now an option for `iterative' yank-last-arg handline, so a user
+ can keep entering `M-.', yanking the last argument of successive history
+ lines.
+
+b. New variable, `print-completions-horizontally', which causes completion
+ matches to be displayed across the screen (like `ls -x') rather than up
+ and down the screen (like `ls').
+
+c. New variable, `completion-ignore-case', which causes filename completion
+ and matching to be performed case-insensitively.
+
+d. There is a new bindable command, `magic-space', which causes history
+ expansion to be performed on the current readline buffer and a space to
+ be inserted into the result.
+
+e. There is a new bindable command, `menu-complete', which enables tcsh-like
+ menu completion (successive executions of menu-complete insert a single
+ completion match, cycling through the list of possible completions).
+
+f. There is a new bindable command, `paste-from-clipboard', for use on Win32
+ systems, to insert the text from the Win32 clipboard into the editing
+ buffer.
+
+g. The key sequence translation code now understands printf-style backslash
+ escape sequences, including \NNN octal escapes. These escape sequences
+ may be used in key sequence definitions or macro values.
+
+h. An `$include' inputrc file parser directive has been added.
+

+d. Pathname canonicalization now leaves a leading `//' intact, as POSIX.1
+ requires.
+
+e. A memory leak when completing commands was fixed.
+
+f. A memory leak that occurred when checking the hash table for commands
+ with relative paths was fixed.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-beta2,
+and the previous version, bash-2.01-beta1.
+
+1. Changes to Bash
+
+a. The `ulimit' builtin translates RLIM_INFINITY to the hard limit only if
+ the current (soft) limit is less than or equal to the hard limit.
+
+b. Fixed a bug that caused the bash emulation of strcasecmp to produce
+ incorrect results.
+
+c. A bug that caused memory to be freed twice when a trap handler resets
+ the trap more than once was fixed.
+
+d. A bug that caused machines where sizeof (pointer) > sizeof (int) to
+ fail (and possibly dump core) when trying to unwind-protect a null
+ pointer was fixed.
+
+e. The startup files should not be run with job control enabled. This fix
+ allows SIGINT to once again interrupt startup file execution.
+
+f. Bash should not change the SIGPROF handler if it is set to something
+ other than SIG_DFL.
+
+g. The completion code that provides bash-specific completions for readline
+ now quotes characters that the readline code would treat as word break
+ characters if they appear in a file name.
+
+h. The completion code now correctly quotes filenames containing a `!',
+ even if the user attempted to use double quotes when attempting
+ completion.
+
+i. A bug that caused the shell to dump core when `disown' was called without
+ arguments and there was no current job was fixed.
+
+j. A construct like $((foo);bar) is now processed as a command substitution
+ rather than as a bad arithmetic substitution.
+
+k. A couple of bugs that caused `fc' to not obey the `cmdhist' and `lithist'
+ shell options when editing and re-executing a series of commands were
+ fixed.
+
+l. A fix was made to the grammar -- the list of commands between `do' and
+ `done' in the body of a `for' command should be treated the same as a
+ while loop.
+
+2. Changes to Readline
+
+a. A couple of bugs that caused the history search functions to attempt to
+ free a NULL pointer were fixed.
+
+b. If the C library provides setlocale(3), readline does not need to look
+ at various environment variables to decide whether or not to go into
+ eight-bit mode automatically -- just check whether the current locale
+ is not `C' or `POSIX'.
+
+c. If the filename completion function finds that a directory was not closed
+ by a previous (interrupted) completion, it closes the directory with
+ closedir().
+
+3. New Features in Bash
+
+a. New bindable readline commands: history-and-alias-expand-line and
+ alias-expand-line. The code was always in there, there was just no
+ way to execute it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-beta1,
+and the previous version, bash-2.01-alpha1.
+
+1. Changes to Bash
+
+a. Fixed a problem that could cause file descriptors used for process
+ substitution to conflict with those used explicitly in redirections.
+
+b. Made it easier to regenerate configure if the user changes configure.in.
+
+c. ${GROUPS[0]} should always be the primary group, even on systems without
+ multiple groups.
+
+d. Spelling correction is no longer enabled by default.
+
+e. Fixes to quoting problems in `bashbug'.
+
+f. OS-specific configuration changes were made for: Irix 6.
+
+g. OS-specific code changes were made for: QNX.
+
+h. A more meaningful message is now printed when the file in /tmp for a
+ here document cannot be created.
+
+i. Many changes to the shell's variable initialization code to speed
+ non-interactive startup.
+
+j. Changes to the non-job-control code so that it does not try to open
+ /dev/tty.
+
+k. The output of `set' and `export' is once again sorted, as POSIX wants.
+
+l. Fixed a problem caused by a recursive call reparsing the value of
+ $SHELLOPTS.
+
+m. The tilde code no longer calls getenv() when it's compiled as part of
+ the shell, which should eliminate problems on systems that cannot
+ redefine getenv(), like the NeXT OS.
+
+n. Fixed a problem that caused `bash -o' or `bash +o' to not list all
+ the shell options.
+
+o. Fixed `ulimit' to convert RLIM_INFINITY to the appropriate hard limit
+ only if the hard limit is greater than the current (soft) limit.
+
+p. Fixed a problem that arose when building bash in a different directory
+ than the source and y.tab.[ch] were remade with something other than
+ bison. This came up most often on NetBSD.
+
+q. Fixed a problem with completion -- it thought that `pwd`/[TAB] indicated
+ an unfinished command completion (`/), which generated errors.
+
+r. The bash special tilde expansions (~-, ~+) are now attempted before
+ calling the standard tilde expansion code, which should eliminate the
+ problems people have been seeing with this on Solaris 2.5.1.
+
+s. Added support for <stdarg.h> to places where it was missing.
+
+t. Changed the code that reads the output of a command substitution to not
+ go through stdio. This reduces the memory requirements and is faster.
+
+u. A number of changes to speed up export environment creation were made.
+
+v. A number of memory leaks were fixed as the result of running the test
+ scripts through Purify.
+
+w. Fixed a bug that caused subshells forked to interpret executable
+ scripts without a leading `#!' to not reinitialize the values of
+ the shell options.
+
+2. Changes to Readline
+
+a. History library has less `#ifdef SHELL' code -- abstracted stuff out
+ into application-specific function hooks.
+
+b. Readline no longer calls getenv() if it's compiled as part of the shell,
+ which should eliminate problems on systems that cannot redefine getenv(),
+ like the NeXT OS.
+
+c. Fixed translation of ESC when `untranslating' macro values.
+
+d. The region kill operation now fixes the mark if it ends up beyond the
+ boundaries of the line after the region is deleted.
+
+3. New Features in Bash
+
+a. New argument for `configure': `--with-curses'. This can be used to
+ override the selection of the termcap library on systems where it is
+ deficient.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.01-alpha1,
+and the previous version, bash-2.0-release.
+
+1. Changes to Bash
+
+a. System-specific configuration changes for: FreeBSD, SunOS4, Irix,
+ MachTen, QNX 4.2, Harris Night Hawk, SunOS5.
+
+b. System-specific code changes were made for: Linux, 4.4 BSD, QNX 4.2,
+ HP-UX, AIX 4.2.
+
+c. A bug that caused the exec builtin to fail because the full pathname of
+ the command could not be found was fixed.
+
+d. The code that performs output redirections is now more resistant to
+ race conditions and possible security exploits.
+
+e. A bug that caused the shell to dump core when performing pattern
+ substitutions on variable values was fixed.
+
+f. More hosts are now recognized by the auto-configuration mechanism
+ (OpenBSD, QNX, others).
+
+g. Assignments to read-only variables that attempt to convert them to
+ arrays are now errors.
+
+h. A bug that caused shell scripts using array assignments in POSIX mode
+ to exit after the assignment was performed was fixed.
+
+i. The substring expansion code is now more careful about running off the
+ ends of the expanded variable value.
+
+j. A bug that caused completion to fail if a backquoted command substitution
+ appeared anywhere on the line was fixed.
+
+k. The `source' builtin no longer turns off history if it has been enabled
+ in a non-interactive shell.
+
+l. A bug that caused the shell to crash when `disown' was given a pid
+ instead of a job number was fixed.
+
+m. The `cd' spelling correction code will not try to change to `.' if no
+ directory entries match a single-character argument.
+
+n. A bad variable name supplied to `declare', `export', or `readonly' no
+ longer causes a non-interactive shell in POSIX mode to exit.
+
+o. Some fixes were made to the test suite to handle peculiarities of
+ various Unix versions.
+
+p. The bash completion code now quotes characters that readline would
+ treat as word breaks for completion but are not shell metacharacters.
+
+q. Bad options supplied at invocation now cause a usage message to be
+ displayed.
+
+r. Fixes were made to the code that handles DEBUG traps so that the trap
+ string is not freed inappropriately.
+
+s. Some changes were made to the bash debugger in examples/bashdb -- it
+ should be closer to working now.
+
+t. A problem that caused the default filename used for mail checking to be
+ wrong was fixed.
+
+u. A fix was made to the `echo' builtin so that NUL characters printed with
+ `echo -e' do not cause the output to be truncated.
+
+v. A fix was made to the job control code so that the shell behaves better
+ when monitor mode is enabled in a non-interactive shell.
+
+w. Bash no longer catches all of the terminating signals in a non-
+ interactive shell until a trap is set on EXIT, which should result in
+ quicker startup.
+
+x. A fix was made to the command timing code so that `time' can be used in
+ a loop.
+
+y. A fix was made to the parser so that `((cmd); cmd2)' is now parsed as
+ a nested subshell rather than strictly as an (erroneous) arithmetic
+ command.
+
+z. A fix was made to the globbing code so that it correctly matches quoted
+ filenames beginning with a `.'.
+
+aa. A bug in `fc' that caused some multi-line commands to not be stored as
+ one command in the history when they were re-executed after editing
+ (with `fc -e') was fixed.
+
+bb. The `ulimit' builtin now attempts to catch some classes of integer
+ overflows.
+
+cc. The command-oriented-history code no longer attempts to add `;'
+ inappropriately when a newline appears while reading a $(...) command
+ substitution.
+
+dd. A bug that caused the shell to dump core when `help --' was executed
+ was fixed.
+
+ee. A bug that caused the shell to crash when an unset variable appeared
+ in the body of a here document after `set -u' had been executed was
+ fixed.
+
+ff. Implicit input redirections from /dev/null for asynchronous commands
+ are now handled better.
+
+gg. A bug that caused the shell to fail to compile when configured with
+ `--disable-readline' was fixed.
+
+hh. The globbing code should now be interruptible.
+
+ii. Bash now notices when the `kill' builtin is used to send SIGCONT to a
+ stopped job and adjusts the data structures accordingly, as if `bg' had
+ been executed instead.
+
+jj. A bug that caused the shell to crash when mixing calls to `getopts'
+ and `shift' on the same set of positional parameters was fixed.
+
+kk. The command printing code now preserves the `-p' flag to `time'.
+
+ll. The command printing code now handles here documents better when there
+ are other redirections associated with the command.
+
+mm. The special glibc environment variable (NNN_GNU_nonoption_argv_flags_)
+ is no longer placed into the environment of executed commands -- users
+ of glibc had too many problems with it.
+
+nn. Reorganized the code that generates signames.h. The signal_names list
+ is now more complete but may be slightly different (SIGABRT is favored
+ over SIGIOT, for example). The preferred signal names are those
+ listed in the POSIX.2 standard.
+
+oo. `bashbug' now uses a filename shorter than 14 characters for its
+ temporary file, and asks for confirmation before sending the bug
+ report.
+
+pp. A bug that caused TAB completion in vi editing mode to not be turned
+ off when `set -o posix' was executed or back on when `set +o posix'
+ was executed was fixed.
+
+qq. A bug in the brace expansion code that caused brace expansions appearing
+ in new-style $(...) command substitutions to be inappropriately expanded
+ was fixed.
+
+rr. A bug in the readline hook shell-expand-line that could cause memory to
+ be inappropriately freed was fixed.
+
+ss. A bug that caused some arithmetic expressions containing `&&' and `||'
+ to be parsed with the wrong precedence has been fixed.
+
+tt. References to unbound variables after `set -u' has been executed now
+ cause the shell to exit immediately, as they should.
+
+uu. A bug that caused the shell to exit inappropriately when `set -e' had
+ been executed and a command's return status was being inverted with the
+ `!' reserved word was fixed.
+
+vv. A bug that could occasionally cause the shell to crash with a
+ divide-by-zero error when timing a command was fixed.
+
+ww. A bug that caused parameter pattern substitution to leave stray
+ backslashes in the replacement string when the expression is in
+ double quotes was fixed.
+
+xx. The `break' and `continue' builtins now break out of all loops when an
+ invalid count argument is supplied.
+
+yy. Fixed a bug that caused PATH to be set to the empty string if
+ `command -p' is executed with PATH unset.
+
+zz. Fixed `kill -l signum' to print the signal name without the `SIG' prefix,
+ as POSIX specifies.
+
+aaa. Fixed a bug that caused the shell to crash while setting $SHELLOPTS
+ if there were no shell options set.
+
+bbb. Fixed `export -p' and `readonly -p' so that when the shell is in POSIX
+ mode, their output is as POSIX.2 specifies.
+
+ccc. Fixed a bug in `readonly' so that `readonly -a avar=(...)' actually
+ creates an array variable.
+
+ddd. Fixed a bug that prevented `time' from correctly timing background
+ pipelines.
+
+2. Changes to Readline
+
+a. A bug that caused an extra newline to be printed when the cursor was on
+ an otherwise empty line was fixed.
+
+b. An instance of memory being used after it was freed was corrected.
+
+c. The redisplay code now works when the prompt is longer than the screen
+ width.
+
+d. `dump-macros' is now a bindable name, as it should have been all along.
+
+e. Non-printable characters are now expanded when displaying macros and
+ their values.
+
+f. The `dump-variables' and `dump-macros' commands now output a leading
+ newline if they're called as the result of a key sequence, rather
+ than directly by an application.
+
+3. New Features in Bash
+
+a. There is a new builtin array variable: GROUPS, the set of groups to which
+ the user belongs. This is used by the test suite.
+
+4. New Features in Readline
+
+a. If a key sequence bound to `universal-argument' is read while reading a
+ numeric argument started with `universal-argument', it terminates the
+ argument but is otherwise ignored. This provides a way to insert multiple
+ instances of a digit string, and is how GNU emacs does it.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-release,
+and the previous version, bash-2.0-beta3.
+
+1. Changes to Bash
+
+a. Fix to the `getopts' builtin so that it does the right thing when a
+ required option argument is not present.
+
+b. The completion code now updates the common prefix of matched names
+ after FIGNORE processing is done, since any names that were removed
+ may have changed the common prefix.
+
+c. Fixed a bug that made messages in MAILPATH entries not work correctly.
+
+d. Fixed a serious documentation error in the description of the new
+ ${parameter:offset[:length]} expansion.
+
+e. Fixes to make parameter substring expansion ({$param:offset[:length]})
+ work when within double quotes.
+
+f. Fixes to make ^A (CTLESC) survive an unquoted expansion of positional
+ parameters.
+
+g. Corrected a misspelling of `unlimited' in the output of `ulimit'.
+
+h. Fixed a bug that caused executable scripts without a leading `#!' to
+ occasionally pick up the wrong set of positional parameters.
+
+i. Linux systems now have a working `ulimit -v', using RLIMIT_AS.
+
+j. Updated config.guess so that many more machine types are recognized.
+
+k. Fixed a bug with backslash-quoted slashes in the ${param/pat[/sub]}
+ expansion.
+
+l. If the shell is named `-su', and `-c command' is supplied, read and
+ execute the login shell startup files even though the shell is not
+ interactive. This is to support the `-' option to `su'.
+
+m. Fixed a bug that caused core dumps when the DEBUG trap was ignored
+ with `trap "" DEBUG' and a shell function was subsequently executed.
+
+n. Fixed a bug that caused core dumps in the read builtin when IFS was
+ set to the null string and the input had leading whitespace.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused a numeric argument of 1024 to be ignored when
+ inserting text.
+
+b. Fixed the display code so that the numeric argument is displayed as it's
+ being entered.
+
+c. Fixed the numeric argument reading code so that `M-- command' is
+ equivalent to `M--1 command', as the prompt implies.
+
+3. New Features in Bash
+
+a. `ulimit' now sets both hard and soft limits and reports the soft limit
+ by default (when neither -H nor -S is specified). This is compatible
+ with versions of sh and ksh that implement `ulimit'.
+
+b. Integer constants have been extended to base 64.
+
+4. New Features in Readline
+
+a. The `home' and `end' keys are now bound to beginning-of-line and
+ end-of-line, respectively, if the corresponding termcap capabilities
+ are present.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-beta3,
+and the previous version, bash-2.0-beta2.
+
+1. Changes to Bash
+
+a. System-specific changes for: AIX 4.2, SCO 3.2v[45], HP-UX.
+
+b. When in POSIX mode, variable assignments preceding a special builtin
+ persist in the shell environment after the builtin completes.
+
+c. Changed all calls to getwd() to getcwd(). Improved check for systems
+ where the libc getcwd() calls popen(), since that breaks on some
+ systems when job control is being used.
+
+d. Fixed a bug that caused seg faults when executing scripts with the
+ execute bit set but without a leading `#!'.
+
+e. The environment passed to executed commands is never sorted.
+
+f. A bug was fixed in the code that expands ${name[@]} to the number of
+ elements in an array variable.
+
+g. A bug was fixed in the array compound assignment code ( A=( ... ) ).
+
+h. Window size changes now correctly propagate down to readline if
+ the shopt `checkwinsize' option is enabled.
+
+i. A fix was made in the code that expands to the length of a variable
+ value (${#var}).
+
+j. A fix was made to the command builtin so that it did not turn on the
+ `no fork' flag inappropriately.
+
+k. A fix was made to make `set -n' work more reliably.
+
+l. A fix was made to the job control initialization code so that the
+ terminal process group is set to the shell's process group if the
+ shell changes its own process group.
+
+2. Changes to Readline
+
+a. System-specific changes for: SCO 3.2v[45].
+
+b. The behavior of the vi-mode `.' when redoing an `i' command was changed
+ to insert the text previously inserted by the `i' command rather than
+ simply entering insert mode.
+
+3. New features in Bash
+
+a. There is a new version of the autoload function package, in
+ examples/functions/autoload.v2, that uses arrays and provides more
+ functionality.
+
+b. Support for LC_COLLATE and locale-specific sorting of the results of
+ pathname expansion if strcoll() is available.
+
+4. New Features in Readline
+
+a. Support for locale-specific sorting of completion possibilities if
+ strcoll() is available.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-beta2,
+and the previous version, bash-2.0-beta1.
+
+1. Changes to Bash
+
+a. `pushd -' is once again equivalent to `pushd $OLDPWD'.
+
+b. OS-specific changes for: SCO 3.2v[45].
+
+c. A change was made to the fix for the recently-reported security hole
+ when reading characters with octal value 255 to make it work better on
+ systems with restartable system calls when not using readline.
+
+d. Some changes were made to the test suite so that it works if you
+ configure bash with --enable-usg-echo-default.
+
+e. A fix was made to the parsing of conditional arithmetic expressions.
+
+f. Illegal arithmetic bases now cause an arithmetic evaluation error rather
+ than being silently reset.
+
+g. Multiple arithmetic bases now cause an arithmetic evaluation error
+ instead of being ignored.
+
+h. A fix was made to the evaluation of ${param?word} to conform to POSIX.2.
+
+i. A bug that sometimes caused array indices to be evaluated twice (which
+ would cause errors when they contained assignment statements) was fixed.
+
+j. `ulimit' was rewritten to avoid problems with getrlimit(2) returning
+ unsigned values and to simplify the code.
+
+k. A bug in the command-oriented-history code that caused it to sometimes
+ put semicolons after right parens inappropriately was fixed.
+
+l. The values inserted into the prompt by the \w and \W escape sequences
+ are now quoted to prevent further expansion.
+
+m. An interactive shell invoked as `sh' now reads and executes commands
+ from the file named by $ENV when it starts up. If it's a login shell,
+ it does this after reading /etc/profile and ~/.profile.
+
+n. The file named by $ENV is never read by non-interactive shells.
+
+2. Changes to Readline
+
+a. A few changes were made to hide some macros and functions that should not
+ be public.
+
+b. An off-by-one error that caused seg faults in the history expansion code
+ was fixed.
+
+3. New Features in Bash
+
+a. The ksh-style ((...)) arithmetic command was implemented. It is exactly
+ identical to let "...". This is controlled by a new option to configure,
+ `--enable-dparen-arithmetic', which is on by default.
+
+b. There is a new #define available in config.h.top: SYS_BASH_LOGOUT. If
+ defined to a filename, bash reads and executes commands from that file
+ when a login shell exits. It's commented out by default.
+
+c. `ulimit' has a `-l' option that reports the maximum amount of data that
+ may be locked into memory on 4.4BSD-based systems.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-beta1,
+and the previous version, bash-2.0-alpha4.
+
+1. Changes to Bash
+
+a. A bug that sometimes caused traps to be ignored on signals the
+ shell treats specially was fixed.
+
+b. The internationalization code was changed to track the values of
+ LC_* variables and call setlocale() as appropriate. The TEXTDOMAIN
+ and TEXTDOMAINDIR variables are also tracked; changes cause calls
+ to textdomain() and bindtextdomain(), if available.
+
+c. A bug was fixed that sometimes caused double-quoted strings to be
+ parsed incorrectly.
+
+d. Changes were made so that the siglist code compiles correctly on
+ Solaris 2.5.
+
+e. Added `:' to the set of characters that cause word breaks for the
+ completion code so that pathnames in assignments to $PATH can be
+ completed.
+
+f. The `select' command was fixed to print $PS3 to stderr.
+
+g. Fixed an error in the manual page section describing the effect that
+ setting and unsetting GLOBIGNORE has on the setting of the `dotglob'
+ option.
+
+h. The time conversion code now uses CLK_TCK rather than CLOCKS_PER_SEC
+ on systems without gettimeofday() and resources.
+
+i. The getopt static variables are now initialized each time a subshell
+ is started, so subshells using `getopts' work right.
+
+j. A sign-extension bug that caused a possible security hole was fixed.
+
+k. The parser now reads characters between backquotes within a double-
+ quoted string as a single word, so double quotes in the backquoted
+ string don't terminate the enclosing double-quoted string.
+
+l. A bug that caused `^O' to work incorrectly when typed as the first
+ thing to an interactive shell was fixed.
+
+m. A rarely-exercised off-by-one error in the code that quotes variable
+ values was fixed.
+
+n. Some memory and file descriptor leaks encountered when running a
+ shell script that is executable but does not have a leading `#!'
+ were plugged.
+
+2. Changes to Readline
+
+a. A bug that sometimes caused incorrect results when trying to read
+ typeahead on systems without FIONREAD was fixed.
+
+3. New Features in Bash
+
+a. The command timing code now uses the value of the TIMEFORMAT variable
+ to format and display timing statistics.
+
+b. The `time' reserved word now accepts a `-p' option to force the
+ POSIX.2 output format.
+
+c. There are a couple of new and updated scripts to convert csh startup
+ files to bash format.
+
+d. There is a new builtin array variable: BASH_VERSINFO. The various
+ members hold the parts of the version information in BASH_VERSION,
+ plus the value of MACHTYPE.
+
+4. New Features in Readline
+
+a. Setting LANG to `en_US.ISO8859-1' now causes readline to enter
+ eight-bit mode.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-alpha4,
+and the previous version, bash-2.0-alpha3.
+
+1. Changes to Bash
+
+a. There is better detection of rsh connections on Solaris 2.
+
+b. Assignments to read-only variables preceding a command name are now
+ variable assignment errors. Variable assignment errors cause
+ non-interactive shells running in posix mode to exit.
+
+c. The word tokenizer was rewritten to handle nested quotes and pairs
+ ('', "", ``, ${...}, $(...), $[...], $'...', $"...", <(...), >(...))
+ correctly. Some of the parameter expansion code was updated as a
+ consequence.
+
+d. A fix was made to `test' when given three arguments so that a binary
+ operator is checked for first, before checking that the first argument
+ is `!'.
+
+e. 2''>/dev/null is no longer equivalent to 2>/dev/null.
+
+f. Parser error messages were regularized, and in most cases the name of
+ the shell script being read by a non-interactive shell is not printed
+ twice.
+
+g. A fix was made to the completion code so that it no longer removes the
+ text the user typed in some cases.
+
+h. The special glibc `getopt' environment variable is no longer put into
+ the environment on machines with small values of ARG_MAX.
+
+i. The expansion of ${...} now follows the POSIX.2 rules for finding the
+ closing `}'.
+
+j. The shell no longer displays spurious status messages for background
+ jobs in shell scripts that complete successfully when the script is
+ run from a terminal.
+
+k. `shopt -o' now correctly updates $SHELLOPTS.
+
+l. A bug that caused the $PATH searching code to return a non-executable
+ file even when an executable file with the same name appeared later in
+ $PATH was fixed.
+
+m. The shell now does tilde expansions on unquoted `:~' in assignment
+ statements when not in posix mode.
+
+n. Variable assignment errors when a command consists only of assignments
+ now cause non-interactive shells to exit when in posix mode.
+
+o. If the variable in a `for' or `select' command is read-only, or not a
+ legal shell identifier, a variable assignment error occurs.
+
+p. `test' now handles `-a' and `-o' as binary operators when three arguments
+ are supplied, and correctly parses `( word )' as equivalent to `word'.
+
+q. `test' was fixed so that file names of the form /dev/fd/NN mean the same
+ thing on all systems, even Linux.
+
+r. Fixed a bug in the globbing code that caused patterns with multiple
+ consecutive `*'s to not be matched correctly.
+
+s. Fixed a bug that caused $PS2 to not be printed when an interactive shell
+ not using readline is reading a here document.
+
+t. Fixed a bug that caused history expansion to be performed inappropriately
+ when a single-quoted string spanned more than one line.
+
+u. `getopts' now checks that the variable name passed by the user as the
+ second argument is a legal shell identifier and that the variable is
+ not read-only.
+
+v. Fixed `getopts' to obey POSIX.2 rules for setting $OPTIND when it
+ encounters an error.
+
+w. Fixed `set' to display variable values in a form that can be re-read.
+
+x. Fixed a bug in the code that keeps track of whether or not local variables
+ have been declared at the current level of function nesting.
+
+y. Non-interactive shells in posix mode now exit if the name in a function
+ declaration is not a legal identifier.
+
+z. The job control code now ignores stopped children when the shell is not
+ interactive.
+
+aa. The `cd' builtin no longer attempts spelling correction on the directory
+ name if the shell is not interactive, regardless of the setting of the
+ `cdspell' option.
+
+bb. Some OS-specific changes were made for SCO 3.2v[45] and AIX 4.2.
+
+cc. `time' now prints its output to stderr, as POSIX.2 specifies.
+
+2. Fixes to Readline
+
+a. After printing possible completions, all lines of a multi-line prompt
+ are redisplayed.
+
+b. Some changes were made to the terminal handling code in rltty.c to
+ work around AIX 4.2 bugs.
+
+3. New Features in Bash
+
+a. There is a new loadable builtin: sprintf, with calling syntax
+ sprintf var format [args]
+ This provides an easy way to simulate ksh left- and right-justified
+ variable values.
+
+b. The expansions of \h and \H in prompt strings were swapped. \h now
+ expands to the hostname up to the first `.', as in bash-1.14.
+
+4. New Features in Readline
+
+a. The bash-1.14 behavior when ^M is typed while doing an incremental
+ search was restored. ^J may now be used to terminate the search without
+ accepting the line.
+
+b. There is a new bindable variable: disable-completion. This inhibits
+ word completion and causes the completion character to be inserted as
+ if it had been bound to self-insert.
+
+------------------------------------------------------------------------------
+This document details the changes between this version, bash-2.0-alpha3,
+and the previous version, bash-2.0-alpha2.
+
+There is now a file `COMPAT' included in the distribution that lists the
+user-visible incompatibilities between 1.14 and 2.0.
+
+1. Changes to Bash
+
+a. Some work was done so that word splitting of the rhs of assignment
+ statements conforms more closely to historical practice.
+
+b. A couple of errant memory frees were fixed.
+
+c. A fix was made to the test builtin so it recognizes `<' and `>' as
+ binary operators.
+
+d. The GNU malloc in lib/malloc/malloc.c now scrambles memory as it's
+ allocated and freed. This is to catch callers that refer to freed
+ memory or assume something about newly-allocated memory.
+
+e. Fixed a problem with conversion to 12-hour time in the prompt
+ expansion code.
+
+f. Fixed a problem with configure's argument parsing order. Now you can
+ correctly turn on specific options after using --enable-minimal-config.
+
+g. The configure script now automatically disables the use of GNU malloc
+ on systems where it's appropriate (better than having people read the
+ NOTES file and do it manually).
+
+h. There are new prompt expansions (\v and \V) to insert version information
+ into the prompt strings.
+
+i. The default prompt string now includes the version number.
+
+j. Most of the builtins that take no options were changed to use the
+ internal getopt so they can produce proper error messages for -?
+ and incorrect options.
+
+k. Some system-specific changes were made for SVR4.2 and Solaris 2.5.
+
+l. Bash now uses PATH_MAX instead of MAXPATHLEN and NAME_MAX instead of
+ MAXNAMLEN.
+
+m. A couple of problems caused by uninitialized variables were fixed.
+
+n. There are a number of new loadable builtin examples: logname, basename,
+ dirname, tty, pathchk, tee, head, and rmdir. All of these conform to
+ POSIX.2.
+
+o. Bash now notices changes in TZ and calls tzset() if present, so
+ changing TZ will alter the time printed by prompt expansions.
+
+p. The source was reorganized a bit so I don't have to wait so long for
+ some files to compile, and to facilitate the creation of a `shell
+ library' at some future point.
+
+q. Bash no longer turns off job control if called as `sh', since the
+ POSIX.2 spec includes job control as a standard feature.
+
+r. `bash -o posix' now works as intended.
+
+s. Fixed a problem with the completion code: when completing a filename
+ that contained globbing characters, if show-all-if-ambiguous was set,
+ the completion code would remove the user's text.
+
+t. Fixed ulimit so that (hopefully) the full range of limits is available
+ on HPUX systems.
+
+u. A new `shopt' option (`hostcomplete') enables and disables hostname
+ completion.
+
+v. The shell no longer attempts to save the history on an abort(),
+ which is usually called by programming_error().
+
+w. The `-s' option to `fc' was changed to echo the command to be executed
+ to stderr instead of stdout.
+
+x. If the editor invoked by `fc -e' exits with a non-zero status, no
+ commands are executed.
+
+y. Fixed a bug that made the shopt `histverify' option work incorrectly.
+
+z. There is a new variable `MACHTYPE' whose value is the GNU-style
+ `cpu-company-system' system description as set by configure. (The
+ values of MACHTYPE and HOSTTYPE should really be swapped.)
+
+aa. The `ulimit' builtin now allows the maximum virtual memory size to be
+ set via setrlimit(2) if RLIMIT_VMEM is defined.
+
+bb. `bash -nc 'command'' no longer runs `command'.
+
+2. Changes to Readline
+
+a. Fixed a typo in the code that checked for FIONREAD in input.c.
+
+b. Fixed a bug in the code that outputs keybindings, so things like C-\
+ are quoted properly.
+
+c. Fixed a bug in the inputrc file parsing code to handle the problems
+ caused by inputrc files created from the output of `bind -p' in
+ previous versions of bash. The problem was due to the bug fixed
+ in item b above.
+
+d. Readline no longer turns off the terminal's meta key, and turns it on
+ once the first time it's called.
+
+------------------------------------------------------------------------------
+This file documents the changes between this version, bash-2.0-alpha2,
+and the previous version, bash-2.0-alpha.
+
+1. Changes to Bash
+
+a. The shell no longer thinks directories are executable.
+
+b. `disown' has a new option, `h', which inhibits the resending of SIGHUP
+ but does not remove the job from the jobs table.
+
+c. The varargs functions in error.c now use ANSI-C `stdarg' if available.
+
+d. The build process now treats the `build version' in .build as local to
+ the build directory, so different versions built from the same source
+ tree have different `build versions'.
+
+e. Some problems with the grammar have been fixed. (It used `list' in a few
+ productions where `compound_list' was needed. A `list' must be terminated
+ with a newline or semicolon; a `compound_list' need not be.)
+
+f. A fix was made to keep `wait' from hanging when waiting for all background
+ jobs.
+
+g. `bash --help' now writes its output to stdout, like the GNU Coding Standards
+ specify, and includes the machine type (the value of MACHTYPE).
+
+h. `bash --version' now prints more information and exits successfully, like
+ the GNU Coding Standards specify.
+
+i. The output of `time' and `times' now prints fractional seconds with three
+ places after the decimal point.
+
+j. A bug that caused process substitutions to screw up the pipeline printed
+ by `jobs' was fixed.
+
+k. Fixes were made to the code that implements $'...' and $"..." so they
+ work as documented.
+
+l. The process substitution code now opens named pipes for reading with
+ O_NONBLOCK to avoid hanging.
+
+m. Fixes were made to the trap code so the shell cleans up correctly if the
+ trap command contains a `return' and we're executing a function or
+ sourcing a script with `.'.
+
+n. Fixes to doc/Makefile.in so that it doesn't try to remake all of the
+ documentation (ps, dvi, etc.) on a `make install'.
+
+o. Fixed an auto-increment error that caused bash -c args to sometimes dump
+ core.
+
+p. Fixed a bug that caused $HISTIGNORE to fail when the history line
+ contained globbing characters.
+
+2. Changes to Readline
+
+a. There is a new string variable, rl_library_version, available for use by
+ applications. The current value is "2.1".
+
+b. A bug encountered when expand-tilde was enabled and file completion was
+ attempted on a word beginning with `~/' was fixed.
+
+c. A slight change was made to the incremental search termination behavior.
+ ESC still terminates the search, but if input is pending or arrives
+ within 0.1 seconds (on systems with select(2)), it is used as a prefix
+ character. This is intented to allow users to terminate searches with
+ the arrow keys and get the behavior they expect.

+
+ 1/9
+ ---
+lib/readline/display.c
+ - fix from Edward Catmur <ed@catmur.co.uk> to logic that handles
+ invisible characters in prompt string. Original code was wrong
+ about local_prompt_prefix; it gave incorrect results when prompt
+ contained invisible characters after a line break
+
+ 1/10
+ ----
+subst.c
+ - new function, mb_substring(), does character (possibly multibyte)
+ oriented rather than strictly byte-oriented substring extraction.
+ The passed indices, rather than strictly indexing into the string,
+ indicate character positions that need to be calculated. From
+ Tim Waugh <twaugh@redhat.com>
+ - change parameter_brace_substring to use mb_substring if necessary
+
+included/shmbutil.h
+ - new define SADD_MBQCHAR_BODY, common code for adding a quoted
+ (preceded by CTLESC) multibyte character to an accumulating string
+ in the subst.c expansion code
+
+subst.c
+ - use SADD_MBQCHAR_BODY in expand_word_internal
+ - new static function, mb_getcharlens, allocates and returns an array
+ of character lengths for (possibly multibyte) characters in the
+ argument string
+ - change pattern matching operations to use while loops instead of
+ for loops to handle multibyte characters better (no more simple
+ increment or decrement)
+ - change pattern matching operations to use multibyte character
+ operations instead of simple increments and decrements. Don't
+ use BACKUP_CHAR_P -- use the mblen array instead, because that
+ avoids the N**2 behavior of having to count from the beginning
+ of the string each time you want to back up one character. Changes
+ to remove_pattern and match_pattern

+ ----
+redir.c
+ - check return value of fclose() in write_here_document() for error
+ returns; don't just rely on fwrite() failing
+
+support/bashbug.sh
+ - set TMPDIR to /tmp if it's null or unset
+ - use $TMPDIR in the TEMP tempfile name template
+ - fixed the call to `mktemp', if it exists, to make it more portable
+
+jobs.c
+ - if WCONTINUED is not defined, define it to 0 and add a define for
+ WIFCONTINUED(wstatus) which expands to 0
+ - add WCONTINUED to the flags passed to waitpid(2) in waitchld()
+ - don't increment children_exited if waitpid's status is WIFCONTINUED,
+ since we don't want to call a SIGCHLD trap handler in this case
+ - in waitchld(), we set child->running to 1 if WIFCONTINUED(status)
+ is non-zero
+ - make sure pretty_print_job doesn't check for the core dump bit if
+ the process has been continued; it's only valid if the job is dead
+ - in set_job_status_and_cleanup, set the job to JRUNNING if job_state
+ is non-zero and the job was previously marked as JSTOPPED
+
+configure.in
+ - add -DBROKEN_DIRENT_D_INO to interix LOCAL_CFLAGS
+
+lib/glob/glob.c
+ - if BROKEN_DIRENT_D_INO is defined, define REAL_DIR_ENTRY to 1
+
+jobs.c
+ - in kill_pid, we only need to block and unblock SIGCHLD if the
+ `group' argument is non-zero, since otherwise we just call `kill'
+ on the pid argument
+
+version.c
+ - update copyright date to 2001
+
+bashline.c
+ - prog_complete_return needs to take a `const char *' as its first
+ argument
+ - history_completion_generator needs to take a `const char *' as
+ its first argument, and `text' needs to be a `const char *'
+
+ 4/11
+ ----
+redir.c
+ - fixed a weird typo in redir_special_open, case RF_DEVFD, added
+ call to all_digits before call to legal_number
+ - fixed do_redirection_internal to call legal_number instead of atol(3)
+ when translating r_duplicating_{in,out}put_word, so it handles
+ overflow better
+ - produce an error message in redirection_error for out-of-range
+ file descriptors
+ - change allocation strategy in redirection_error so we don't have to
+ malloc scratch memory if redirection_expand() fails
+
+jobs.h
+ - added defines for `running' member of a struct process
+
+general.c
+ - fix legal_number to return 0 when strtol(3) reports overflow or
+ underflow
+
+parse.y
+ - changed read_token_word to call legal_number instead of atoi(3)
+
+input.c
+ - return -1/EBADF from close_buffered_fd if fd is < 0

+ - fixed bogus comment about IS_DESCRIPTOR in description of the
+ REDIRECTEE struct
+
+print_cmd.c
+ - change cprintf's 'd' modifier code to display negative numbers as
+ an out-of-range value. We can do this only because the only use
+ of %d is to output file descriptor numbers in redirections
+
+support/mksignames.c

+patchlevel.h
+ - new file, contains define for PATCHLEVEL. Doing away with the old
+ scheme of having the information in configure.in
+
+version.c
+ - include patchlevel.h
+
+Makefile.in
+ - run bashversion -p to find patch level rather than have configure
+ substitute in a value
+ - pass -S ${top_srcdir} to support/mkversion.sh
+
+support/mkversion.sh
+ - don't put PATCHLEVEL define into version.h, but accept and ignore
+ a -p option
+ - take a new -S srcdir option
+ - find the patch level by parsing it out of patchlevel.h
+
+configure.in
+ - hard-code BASHVERS assignment instead of reading it from a file
+ - remove BASHPATCH; don't substitute it
+
+_distribution,_patchlevel

+ ----
+shell.c
+ - call init_noninteractive() in open_shell_script if forced_interactive
+ is non-zero (the shell was started with -i) and fd_is_tty is 0
+ (the script file is a real file, not something like /dev/stdin),
+ since it wasn't done earlier
+
+builtins/printf.def
+ - change for POSIX.2 compliance when conversion errors are encountered
+ when processing %d, %u, and floating point conversion operators
+ (print a warning message, return the value accumulated at the time
+ of the error -- which is always 0 -- and exit with a non-zero status)
+
+command.h
+ - added CMD_COMMAND_BUILTIN for use by the `command' builtin and the
+ code in execute_cmd.c
+
+builtins/command.def
+ - add CMD_COMMAND_BUILTIN to the created command's flags

+
+builtins/evalfile.c
+ - added FEVAL_REGFILE (file must be a regular file) to accepted
+ _evalfile flags
+ - fc_execute_file() adds FEVAL_REGFILE to _evalfile flags. This

+
+lib/sh/netopen.c
+ - change _getserv() to reject negative port/service numbers

+ - include <limits.h> if it's present

+{execute_cmd,lib/sh/itos,pcomplete,print_cmd,subst,variables}.c
+ - use INT_STRLEN_BOUND instead of static array sizes when converting

+
+ 5/8
+ ---
+aclocal.m4
+ - add check for libtinfo (termcap-specific portion of ncurses-5.2) to

+
+configure.in
+ - call RL_LIB_READLINE_VERSION instead of support/rlvers.sh
+
+execute_cmd.c
+ - fix execute_shell_script and the WHITECHAR and STRINGCHAR macros

+jobs.c
+ - use unwind_protect_var on last_made_pid in run_sigchld_trap

+ as longs
+
+builtins/history.def
+ - consolidate tests for valid history position in one block to

+
+builtins/ulimit.def
+ - fix check for overflow when setting limit to work when int is 32

+
+lib/sh/tmpfile.c
+ - don't truncate the result of time(3) to int; just use time_t,
+ since it's being assigned to an `unsigned long'
+
+mailcheck.c
+ - use legal_number instead of atoi in time_to_check_mail() to catch

+ - call AC_CHECK_FUNCS on ctype.h functions/macros that bash redefines
+ in chartypes.h
+
+config.h.in
+ - defines for HAVE_IS{ASCII,BLANK,GRAPH,PRINT,SPACE,XDIGIT}
+
+include/chartypes.h, lib/glob/strmatch.c, lib/readline/chardefs.h
+ - don't redefine some is* ctype macros/functions if HAVE_ISXXX is
+ defined (meaning that an appropriate function, but not a macro,
+ exists)
+
+lib/sh/strtrans.c
+ - new function, ansic_shouldquote, returns 1 if argument string
+ contains non-printing chars that should be quoted with $'...'
+
+externs.h
+ - new declaration for ansic_shouldquote()
+
+variables.c
+ - change print_var_value to ansi C quote the string if we're not in
+ posix mode and the variable's value contains non-printing chars,
+ to use the regular shell single quoting if the value contains
+ shell meta-characters, and to just output the string otherwise
+
+lib/sh/shquote.c
+ - add `break' to `case '~':' to avoid fallthrough and extra test
+
+doc/bashref.texi
+ - note that in POSIX mode, `set' displays variable values that
+ include nonprinting characters without quoting, unless they
+ contain shell metacharacters
+
+builtins/printf.def, lib/sh/snprintf.c
+ - handle `F' conversion specifier as equivalent to 'f'
+
+parse.y, {nojobs,variables}.c
+ - a couple of cleanups for when building a minimal configuration
+
+nojobs.c
+ - new function: stop_making_children(), just sets
+ already_making_children to 0 (like stop_pipeline)
+
+subst.c
+ - call stop_making_children from subst.c:command_substitute if
+ JOB_CONTROL is not defined. This fixes the bug where the wrong
+ process is waited for (and its status returned) when using
+ command substitution in a null command in a shell function
+
+builtins/printf.def
+ - new variable `tw' used to keep track of the total number of
+ characters written by a single call to `printf' -- to be
+ used for the `%n' conversion, which will be added later. It
+ gets reset each time we reuse the format string, which is what
+ ksh93 seems to do
+
+ 10/23
+ -----
+variables.c
+ - new function, bind_var_to_int (char *var, long val)
+
+variables.h
+ - extern declaration for bind_var_to_int
+
+lib/sh/netopen.c
+ - use gai_strerror() for error messages when getaddrinfo() fails
+ - use PF_INET if DEBUG is defined, since IPv6 doesn't work for me
+
+Makefile.in
+ - pass DEBUG=${DEBUG} down to makes in some subdirectories
+
+{builtins,lib/{glob,sh}}/Makefile.in
+ - append ${DEBUG} to LOCAL_CFLAGS value, passed by top-level Makefile
+
+builtins/printf.def
+ - added support for %n format conversion char (number of chars printed
+ so far from current format string)
+
+ 10/24
+ -----
+variables.c
+ - if posixly_correct is set, the default value of $MAILCHECK is 600
+ - use legal_number instead of atoi in adjust_shell_level
+ - treat non-numeric assignments to SECONDS as 0 in assign_seconds
+ - new function, init_funcname_var; sets FUNCNAME as a dynamic variable
+ if it's not set in the initial environment
+ - new function, init_groups_var; sets GROUPS as a dynamic array
+ variable if it's not set in the initial environment
+ - new function, init_dirstack_var; sets DIRSTACK as a dynamic array
+ variable if it's not set in the initial environment
+ - new function, init_seconds_var; sets SECONDS as a dynamic
+ variable using any valid integer value in the initial environment
+ as the initial value, as if an assignment had been performed
+ - call init_funcname_var, init_groups_var, init_dirstack_var,
+ init_seconds_var from initialize_dynamic_variables
+ - non-numeric values assigned to LINENO are treated as 0
+ - change initialize_shell_variables to not auto-export PATH or TERM
+ - change set_home_var to not auto-export HOME
+ - change set_shell_var to not auto-export SHELL
+ - broke the code that sets HOSTNAME, HOSTTYPE, MACHTYPE, OSTYPE
+ out into a separate function, set_machine_vars; none of those
+ variables are auto-exported
+ - bash no longer un-exports SSH_CLIENT or SSH2_CLIENT
+
+shell.c
+ - changed isnetconn() to check SSH_CLIENT and SSH2_CLIENT only if
+ SSH_SOURCE_BASHRC is defined in config-top.h
+
+config-top.h
+ - added a commented-out definition for SSH_SOURCE_BASHRC
+
+ 10/25

+ LC_NUMERIC
+
+doc/{bash.1,bashref.texi}

+
+doc/builtins.1

+
+lib/readline/readline.c

+
+lib/readline/util.c
+ - don't compile in _rl_strpbrk if HAVE_STRPBRK is defined
+
+lib/readline/rlprivate.h
+ - remove extern declaration of _rl_strpbrk
+
+lib/readline/rldefs.h
+ - #define _rl_strpbrk as strpbrk if HAVE_STRPBRK is define, otherwise
+ add extern declaration of _rl_strpbrk from rlprivate.h
+
+{mailcheck,shell,variables}.c

+ in scope
+
+{array,eval,execute_cmd,mksyntax,subst}.c, parse.y
+builtins/common.c
+lib/sh/pathcanon.c
+ - a few changes as the result of `gcc -Wall' patches from solar

+
+builtins/read.def, parse.y
+ - change some calls to free() to xfree()
+
+builtins/set.def
+ - make sure unset_builtin() resets unset_array to 0 each time through
+ the loop, because it's set (and used) depending on the current
+ argument
+
+shell.h
+ - new define, USE_VAR, to force the compiler to not put a particular
+ variable in a register -- helpful if registers are not restored
+ by setjmp/longjmp
+
+builtins/{evalfile.c,{read,wait}.def}, {eval,execute_cmd,shell,test}.c
+ - use USE_VAR for some variables
+
+subst.c
+ - fixed a case in expand_word_internal where a NULL pointer could
+ have been passed to free() (though free() should ignore it)
+ - fixed a case at the end of expand_word_internal where LIST could
+ have been used uninitialized (it makes gcc happy, though it
+ doesn't happen in practice)
+
+test.c
+ - give test_syntax_error(), beyond(), and integer_expected_error()
+ the `__noreturn__' attribute for gcc
+
+unwind_prot.c
+ - in clear_unwind_protect_list(), convert `flags' to `long' (via
+ assignment to a `long' variable) before casting to `char *', in
+ case pointers and longs are 64 bits and ints are 32 (makes no
+ difference on 32-bit machines)
+
+ 10/30
+ -----
+print_cmd.c
+ - fixed cprintf to avoid gcc warning about assigning const pointer
+ to non-const (discarding type qualifier)
+
+{make_cmd,pcomplete,test}.c,parse.y
+ - some minor changes to shut up gcc warnings
+
+lib/sh/tmpfile.c
+ - fixed sh_mktmpfp to avoid file descriptor leaks in the case that
+ sh_mktmpfd succeeds but fdopen fails for some reason
+ - change sh_mktmpfd to use the same scheme for computing `filenum'
+ as sh_mktmpname
+ - change get_sys_tmpdir to prefer P_tmpdir if P_tmpdir is defined
+ - changed sh_mktmpname and sh_mktmpfd to avoid trying to assign to
+ `nameroot' if `nameroot == 0' (duh)
+ - add code to sh_mktmpfd to use mkstemp(3) if USE_MKSTEMP is defined
+ - add code to sh_mktmpname to use mktemp(3) if USE_MKTEMP is defined
+
+support/{fixlinks,mkclone}
+ - use mktemp if it's available for the symlink test
+ - use $TMPDIR instead of hardcoding /tmp; default to /tmp
+ - use a better filename for the symlink test instead of `z'
+
+support/bashbug.sh
+ - more changes inspired by a patch from solar designer
+
+lib/malloc/Makefile.in
+ - new target `alloca', which builds libmalloc.a with alloca.o only
+ (for systems without alloca that are configured --without-bash-malloc)
+
+configure.in
+ - if we don't have a working alloca and are not configured to build
+ the bash malloc library, make a malloc library containing only
+ alloca.o
+
+aclocal.m4
+ - slight change to RL_LIB_READLINE_VERSION to deal with minor version
+ numbers with a letter appended (like 4.2a)
+
+ 10/31
+ -----
+doc/{bash.1,bashref.texi}
+ - slight change to note that only interactive shells resend a SIGHUP
+ to all jobs before exiting
+
+externs.h
+ - declare strto[ui]max only if NEED_STRTOIMAX_DECL is defined. This
+ keeps picky compilers from choking because intmax_t is not defined
+ (MacOS X 10.1)
+
+builtins/printf.def
+ - #define NEED_STRTOIMAX_DECL before including shell.h
+
+ 11/1

+general.c
+ - check in bash_tilde_expand() for an unquoted tilde-prefix; don't

+[bash-2.05a-rc1 frozen]
+
+builtins/printf.def
+ - fix the %n conversion to require that the variable name supplied

+ bits of the running random number instead of the lower 16, which
+ are incrementally more random

+doc/{bash.1,bashref.texi}
+ - correct description of POSIXLY_CORRECT to note that the shell enters
+ posix mode *before* the startup files are read if POSIXLY_CORRECT
+ is in the initial environment
+
+variables.c
+ - fix function prologues for init_dirstack_var and init_groups_var
+ to agree with caller (no arguments)
+
+jobs.c
+ - fix forward function declarations for pipe_read and pipe_close
+
+subst.c
+ - removed `inline' attribute from skip_double_quoted because it can
+ potentially be called recursively
+
+bashline.c
+ - quick fix to bashline.c:attempt_shell_completion programmable
+ completion code to just punt if the end of the command word found
+ by find_cmd_end is <= the start found by find_cmd_start (the bug
+ is probably in find_cmd_start -- fix later)
+
+pcomplete.c
+ - fix gen_matches_from_itemlist to return if the stringlist is null
+ after any cleaning or initialization, before trying to use it
+ - fix GEN_COMPS to only bother to try to append the STRINGLIST
+ returned by gen_matches_from_itemlist to `glist' if it's non-NULL
+
+lib/sh/stringlist.c
+ - make copy_stringlist return NULL if the STRINGLIST * passed as an

+ - make append_stringlist call copy_stringlist only if M2 is non-NULL;
+ otherwise just return NULL if m1 is NULL
+ - make word_list_to_stringlist return 0 immediately if the passed
+ LIST argument is NULL
+ - make realloc_stringlist call alloc_stringlist if the passed
+ STRINGLIST argument (`sl') is 0, just like realloc calls malloc
+
+subst.c
+ - in skip_to_delim(), if we have an unclosed ${, and it's at the end
+ of the string (string[i] == '{', string[i+1] == '{' and
+ string[i+2] == 0, return si (i +2) immediately without bothering
+ to call extract_dollar_brace_string or extract_delimited_string
+ - in skip_to_delim(), if string[i] is 0 after a call to
+ extract_dollar_brace_string or extract_delimited_string (meaning we
+ have an unclosed ${ or other expansion, return i immediately without
+ doing a `continue' (which will increment i past the end of string)
+ - in split_at_delims, don't increment te by 1 if it's pointing to a
+ delimiter. this has the effect of skipping the first delimiter
+ char in a possibly multi-character delimiter, and ignoring
+ single-char delimiters like `>'
+
+configure.in
+ - use AC_CHECK_MEMBERS([struct stat.st_blocks]) instead of a call to
+ AC_STRUCT_ST_BLOCKS to avoid configure changing LIBOBJS if the test
+ fails
+
+general.c
+ - introduce two new variables: bash_tilde_{prefixes,suffixes}, set
+ to the additional prefixes and suffixes bash wants to pass to the
+ tilde expansion code (reserved for post-bash-2.05a fix)
+
+aclocal.m4
+ - add missing `test' in BASH_CHECK_SYS_SIGLIST
+
+ 11/7
+ ----
+lib/readline/vi_mode.c
+ - fix rl_vi_goto_mark to explicitly check that the desired mark is
+ between 'a' and 'z', since some locales have lowercase letters
+ outside that range, which could cause a negative subscript
+
+include/chartypes.h
+ - remove superfluous `#undef ISASCII'
+
+lib/sh/strto[iu]max.c
+ - changes from Paul Eggert to work around buggy compilers and catch
+ configuration errors at compile time
+
+aclocal.m4
+ - new macro, BASH_C_LONG_DOUBLE, identical to AC_C_LONG_DOUBLE but
+ with a fix for Irix 5.3 (not called, since I'm not sure it's the
+ right thing to do -- the C standard allows double and long double
+ to be the same size)
+
+lib/sh/snprintf.c
+ - only try to write the trailing NUL in vsnprintf_internal if
+ data->length is >= 0, since if it's not, we probably don't have

+{arrayfunc,variables}.c
+ - changed calling sequence for dynamic array variable `assign'
+ functions to (SHELL_VAR *self, char *value, arrayind_t ind)
+ - changed calling sequence for dynamic variable assign functions
+ to the same as array variable assign_func. Now this can be
+ prototyped
+
+variables.h
+ - the assign_func member of a `struct variable' is now of type
+ `sh_var_assign_func_t', which is prototyped
+ - the dynamic_value member of a `struct variable' is now of type
+ `sh_var_value_func_t', which is prototyped
+
+variables.c
+ - changed to use `sh_var_assign_func_t' and `sh_var_value_func_t'
+
+builtins/cd.def
+ - when in posix mode, if the new directory name formed by PWD and

+ - if canonicalization failed, but the fallback to the directory
+ name specified by the user succeeds, reset the current working

+
+lib/readline/{input.c,rlprivate.h}
+ - renamed rl_unget_char to _rl_unget_char; made library global
+
+lib/readline/{{bind,readline}.c,{keymaps,rlprivate}.h}
+ - support for `key subsequences'; allows a key sequence and a function
+ mapped to a subsequence of that key sequence. Primarily to allow
+ arrow keys to be bound in readline vi insert mode, while preserving
+ the ESC function to switch to command mode.
+
+lib/readline/{input.c,rlprivate.h}
+ - new function, _rl_input_queued(T), does a check with select or
+ FIONREAD with a timeout of `T' (which is generally 0)
+
+lib/readline/readline.c
+ - change _rl_dispatch_subseq to test for input in the queue if we
+ get ESC while in vi insertion mode if the keymap entry type for
+ ESC is ISKMAP. If _rl_input_queued returns non-zero, we assume
+ that an arrow key sequence has been pressed and go ahead with the
+ subsequence. If it returns zero, we assume that the user pressed
+ ESC to switch into command mode, and dispatch to that right away.
+ This avoids forcing the user to press another key before switching
+ into command mode
+
+ 11/21
+ -----
+lib/readline/readline.c
+ - bind common arrow key sequences in vi insertion keymap
+
+lib/readline/terminal.c
+ - bind termcap definition's arrow keys in vi insertion keymap
+
+lib/readline/bind.c
+ - check for rl_vi_movement_mode in _rl_bind_if_unbound, so
+ binding the arrow keys can work
+
+lib/readline/readline.c
+ - since _rl_bind_if_unbound does the check of what's currently
+ bound to the key sequence, the check in bind_arrow_keys_internal
+ was redundant
+ - bind_arrow_keys_internal now takes a Keymap argument and handles
+ saving and restoring _rl_keymap; changed bind_arrow_keys
+ accordingly
+
+builtins/fc.def
+ - fix from Paul Eggert to substitute the nearest history number in

+
+lib/sh/pathcanon.c
+ - fix from Corrina Vinschen for the special `cygdrive' prefix on

+
+bashhist.c
+ - split the history adding code into more pieces:
+ check_history_control (char *line) checks LINE against the value
+ of HISTCONTROL, returning 1 if LINE should be saved and 0 if not
+
+ check_add_history (char *line) calls check_history_control and
+ history_should_ignore (line) and saves the line with
+ bash_add_history if the checks indicate that it should be saved
+
+ maybe_add_history just calls check_add_history to set the value
+ of first_line_saved
+
+bashhist.h
+ - extern declaration for check_add_history()
+
+shell.c
+ - don't call load_history() from the interactive shell startup
+ code if history_lines_this_session is > 0, indicating that we've
+ already saved some lines in the history and that we probably
+ don't want to overwrite them
+
+builtins/history.def
+ - call check_add_history from push_history, so `history -s xx'
+ works even when in a compound command whose first line has not
+ been saved. (Caveat: in a compound command when the first
+ line has been saved, the line supplied to history -s will become
+ part of the compound command's history entry. Of course, the
+ delete_history call could remove the compound command from the

+
+bashline.c
+ - use sh_makepath instead of xmalloc/sprintf in

+
+lib/readline/complete.c
+ - get_y_or_n now takes an int FOR_PAGER argument; caller changed
+ If FOR_PAGER is non-zero, get_y_or_n returns appropriate values
+ for a more-like pager: `newline' or `return' return 2; `q' or
+ `Q' return 0
+ - there is now a mini internal more-like pager for displaying a

+
+bashline.c
+ - fix attempt_shell_completion to turn off

+
+ 11/26
+ -----
+lib/readline/rltech.texinfo
+ - a couple of additions to the rl_stuff_char description
+

+ - turn off echo_input_at_read in parse_string_to_word_list, so `set -v'
+ doesn't give extra lines of output when doing compound array

+ - new extern declaration for find_token_in_alist()
+
+subst.c
+ - string_list_internal is no longer static
+
+subst.h
+ - new extern declaration for string_list_internal()
+
+parse.y
+ - new alist array of other tokens returned by read_token which are
+ not reserved words in word_token_alist[]
+ - reworked error reporting: new functions print_offending_line,
+ which prints the line containing the syntax error,
+ error_token_from_token, which takes the current token and tries to
+ figure out its textual representation, and error_token_from_text,
+ which does the old job of finding the bad token by analyzing the
+ text of shell_input_line at the current index
+ - report_syntax_error now tries to figure out the token that caused
+ the syntax error by first looking at current_token and falling
+ back to the old method of textual analysis if that fails
+ - report_syntax_error doesn't say the token resulting from the textual
+ analysis of the input line is an `unexpected token'; it just
+ says there is a `syntax error near xxx'
+ - changed conditional command error reporting to use the value
+ returned by error_token_from_token if it's not null instead of
+ just using the token value in the message, since current_token
+ ends up being set to -1, and the text of the message from
+ report_syntax_error might not be exactly right
+ - change parse_string_to_word_list to set current_token to the
+ offending token returned by read_token before calling yyerror()
+ to make the error reporting do the right thing
+
+aclocal.m4
+ - fixed typo in BASH_CHECK_LIB_TERMCAP
+

+ - use the current locale for thousands separator and decimal point
+ - recognize "'" flag; not implemented yet
+ - fix for snprintf/vsnprintf with length of 0 and string argument of
+ 0 with non-zero length
+
+builtins/read.def
+ - TMOUT is now the default timeout for `read' (and select) if set,
+ like ksh93 when reading from the terminal
+ - edit_line (called by read -e) now just does readline's filename
+ completion by setting rl_attempted_completion_function to NULL,
+ since e.g., doing command completion for the first word on the
+ line wasn't really useful
+
+execute_cmd.c
+ - changed select_command to return failure status if select_query
+ returns NULL, indicating that read_builtin returned
+ EXECUTION_FAILURE
+
+doc/{bash.1,bashref.texi}
+ - documented new TMOUT behavior
+ - slight change to the description of the test `-ef' option
+
+doc/bashref.texi
+ - added item to posix mode section describing failure behavior of
+ cd when invoked in logical mode and the pathname formed by
+ combining $PWD and the directory argument does not refer to an
+ existing directory
+
+ 11/29
+ -----
+execute_cmd.c
+ - fix execute_function to call dispose_function_env after
+ merge_function_env if the shell is in posix mode (fixes debian
+ bash bug #117673)
+
+lib/readline/readline.c
+ - rl_forward -> rl_forward_char; rl_forward function for compatibility
+ - rl_backward -> rl_backward_char; rl_forward function for
+ compatibility
+ - new functions, rl_forward_byte, rl_backward_byte, for future use
+
+lib/readline/readline.h
+ - extern declarations for rl_forward_char, rl_backward_char,
+ rl_forward_byte, rl_backward_byte
+
+lib/readline/{emacs_keymap,funmap,vi_keymap,vi_mode
+ - rl_forward -> rl_forward_char

+
+aclocal.m4
+ - new function, BASH_CHECK_MULTIBYTE, encapsulates checks for
+ multibyte code
+
+config.h.in
+ - add necessary defines for multibyte include files and functions

+ - add call to BASH_CHECK_MULTIBYTE
+
+config-bot.h
+ - add code to define HANDLE_MULTIBYTE if prerequisites are met
+
+lib/sh/xstrchr.c
+ - new file, xstrchr() is strchr(3) that handles multibyte characters
+
+bashhist.c
+ - first_line_saved -> current_command_first_line_saved; variable is
+ now global
+
+bashhist.h
+ - extern declaration for current_command_first_line_saved
+
+ 11/30
+ -----
+bashhist.c
+ - break the code that actually calls add_history out of
+ bash_add_history into a new function, really_add_history;
+ bash_add_history now calls really_add_history
+ - check_add_history takes a second `force' argument telling it
+ whether to call bash_add_history (force == 0) or really_add_history
+ (force != 0)
+
+builtins/history.def
+ - in push_history, call delete_last_history if the current command
+ has more than one line, the first line was saved, and
+ command-oriented history is active. This takes care of deleting
+ the right history element if `history -s' is used within a
+ compound or multiline command
+ - in push_history, call check_add_history with second argument of 1
+ to skip check of current_command_line_count and add the arguments
+ to history -s as a single separate history entry
+
+ 12/3
+ ----
+lib/readline/complete.c
+ - append a slash to completed names which are symlinks to directories
+ if the new variable _rl_complete_mark_symlink_dirs is non-zero
+
+lib/readline/rlprivate.h
+ - extern declaration for _rl_complete_mark_symlink_dirs
+
+lib/readline/bind.c
+ - new bindable variable, `mark-symlinked-directories', mirrors the
+ value of _rl_complete_mark_symlink_dirs
+
+doc/bash.1, lib/readline/doc/{readline.3,rluser.texinfo}
+ - documented new `mark-symlinked-directories' variable
+
+ 12/4
+ ----
+variables.[ch]
+ - set_pipestatus_array now takes a second argument with the number
+ of processes in the array
+ - changed set_pipestatus_array to just modify the value in place if
+ the existing array has one element and the new array has one
+ element, and to modify existing values in place if new array has
+ more elements than existing array
+
+variables.c, jobs.c
+ - changed set_pipestatus_array callers
+
+jobs.c
+ - moved call to setjstatus() from set_job_status_and_cleanup to
+ wait_for, since set_job_status_and_cleanup is part of the SIGCHLD
+ signal handler call path, and race conditions accessing the
+ PIPESTATUS array will result for things like
+
+ while true; do date; done | cat > /dev/null
+
+ 12/5
+ ----
+xmalloc.h
+ - don't redefine xmalloc, xrealloc, and xfree if DISABLE_MALLOC_WRAPPERS
+ is #defined
+
+config.h.in
+ - #undef for DISABLE_MALLOC_WRAPPERS
+
+configure.in
+ - define DISABLE_MALLOC_WRAPPERS if the --with-purify option is

+
+lib/malloc/trace.c
+ - new function, malloc_trace_bin(N), traces allocations and frees
+ to bucket N (uses the same type of bitmap as `busy')
+
+lib/malloc/table.c
+ - fix wraparound search problem in find_entry when searching for a
+ free entry when the table is full
+
+ 12/6
+ ----
+lib/malloc/table.c
+ - keep an `overflow bucket' around to use when the table is full,
+ so find_entry always returns a valid pointer when FIND_ALLOC
+ is set
+ - new static variable to keep a count of the number of MT_ALLOC
+ entries in the mem_table
+
+lib/sh/{oslib,clktck}.c
+ - if HAVE_LIMITS_H is defined, include <limits.h>
+
+lib/sh/oslib.c

+ - necessary changes for netconn.c
+
+builtins/ulimit.def
+ - changed getmaxuprc() to just call getmaxchild() and massage the
+ return value appropriately
+
+{jobs,nojobs}.c
+ - use the value returned by getmaxchild() in
+ mark_dead_jobs_as_notified instead of static CHILD_MAX
+
+jobs.c
+ - new function, compact_jobs_list, removes some number of jobs from
+ the jobs table and reallocates the table, copying the jobs that
+ are left from the old table to the new. Compaction happens from
+ the beginning of the list and removes dead jobs, and we make sure
+ to keep the last CHILD_MAX jobs as POSIX.2 requires
+ - call compact_jobs_list from stop_pipeline if we're in a subshell,
+ there are no free jobs in the jobs table, and the jobs table is
+ at or above some maximum limit
+
+execute_cmd.c
+ - change eval_arith_for_expr to set this_command_name to `((' before
+ calling evalexp, since it might be changed by evaluating the
+ loop body between evalexp calls
+
+trap.c
+ - change reset_signal to turn off the SIG_TRAPPED flag for the
+ given signal, so shell builtins and functions running in command
+ substitutions don't run the signal handlers (traps are not supposed
+ to be inherited by command substitutions)
+
+parse.y
+ - changed parse_string_to_word_list to turn off alias expansion
+ while parsing the array assignment
+
+ 12/9
+ ----
+alias.c
+ - fix add_alias so that redefining an alias's value also resets the
+ EXPANDNEXT flag
+
+ 12/10
+ -----
+parse.y
+ - new function, token_is_assignment, called to check whether the text
+ before `=' makes up a valid assignment token before trying to parse
+ a compound assignment statement
+ - new function, parse_compound_assignment, to parse a compound
+ assignment statement instead of using parse_matched_pair; handles
+ comments and error reporting in the parser instead of waiting until
+ expansion time
+ - changed parse_compound_assignment and parse_string_to_word_list to
+ allow reserved words in compound array assignments
+
+lib/readline/doc/rltech.texinfo
+ - changed the documentation for rl_callback_read_char and
+ rl_callback_handler_remove to say what happens to the terminal
+ settings and what needs to be done to reset them
+
+ 12/11
+ -----
+bashline.c
+ - add emacs_edit_and_execute_command, bound to C-xC-e, like vi-mode
+ `v' command
+ - add bindable command name `edit-and-execute-command', bound to
+ run emacs_edit_and_execute_command()
+
+lib/glob/strmatch.c
+ - add support for ksh93-like [:word:] character class (isalnum + `_')
+
+doc/{bash.1,bashref.texi}
+ - add note to section describing lists to clarify that a sequence of
+ one or more newlines may be used to delimit a command, equivalent
+ to a semicolon
+ - document new [:word:] pattern matching character class
+
+doc/bash.1, lib/readline/doc/rluser.texinfo

+
+lib/sh/strtrans.c
+ - add \cX (Control-X) escape for $'...' to ansicstr()
+ - change ansic_quote() to allocate at least four chars for each char
+ in the string argument, to account for \0xx octal values
+ - change ansic_quote() to no longer call sprintf for non-printable
+ characters; just translate the string to octal directly
+
+print_cmd.c
+ - change xtrace_print_word_list to call ansic_quote() if
+ ansic_shouldquote() indicates that there are nonprinting characters
+ in a word
+
+builtins/type.def
+ - changed deprecated long option parsing to just replace the word
+ in the list with the equivalent short option (-type -> -t) instead
+ of removing words from the list
+ - changed describe_command to take a single flags argument instead
+ of two int args; changed caller
+ - type now has two new options: -f suppresses function lookup (like
+ command), and -P forces a PATH search for the name(s)
+
+builtins/common.h
+ - flags for describe_command are here
+ - changed extern declaration of describe_command
+
+builtins/command.def
+ - changed call to describe_command to use flags from common.h, and
+ the right number of arguments
+
+doc/{bash.1,bashref.texi}
+ - documented new -f and -P options to `type'
+
+ 12/12
+ -----
+lib/readline/rldefs.h
+ - fixed prototype for _rl_strnicmp
+
+execute_cmd.c
+ - select_query now takes a new argument, an int flag saying whether
+ or not to print the menu the first time through the loop. An
+ empty line in response to the prompt will always cause the menu
+ to be reprinted
+ - changed execute_select_command to cause select_query to reprint
+ the menu only if REPLY is set to NULL, if KSH_COMPATIBLE_SELECT
+ is defined
+
+config-top.h
+ - define KSH_COMPATIBLE_SELECT, with a comment about its meaning
+
+lib/readline/readline.c
+ - change rl_insert_comment to toggle if given an explicit numeric
+ argument: if the first characters on the line don't specify a
+ comment, insert one; if they do, delete the comment text
+
+doc/bash.1, lib/readline/doc/{readline.3,rluser.texinfo}
+ - documented new behavior of insert-comment with a numeric argument

+ - added calls to _malloc_ckwatch in internal_malloc, internal_free,
+ and internal_realloc
+
+include/stdc.h
+ - augment __P define to allow prototypes if PROTOTYPES is defined
+
+lib/readline/rlstdc.h
+ - augment PARAMS define to allow prototypes if PROTOTYPES is defined
+
+lib/malloc/Makefile.in, Makefile.in
+ necessary changes to include watch.c in libmalloc
+
+lib/readline/readline.c
+ - fix rl_delete_text to make sure that the starting position is >= 0
+ - _rl_init_line_state (called by readline via readline_initialize)
+ now sets rl_mark to 0
+ - rl_get_{next,previous}_history set rl_mark to 0 if rl_point is at
+ the end of the line and rl_end otherwise in emacs mode
+
+lib/readline/kill.c
+ - rl_yank_nth_arg_internal and rl_paste_clipboard now set the mark
+ at point before calling rl_insert_text, like rl_yank
+ - rl_kill_full_line now resets rl_mark to 0
+ - rl_kill_line and rl_backward_kill_line now set rl_mark to the
+ point after the kill in emacs mode
+ - rl_kill_word and rl_backward_kill_word now set rl_mark to the
+ point after the kill in emacs mode
+ - rl_unix_word_rubout and rl_unix_line_discard now set rl_mark to
+ the point after the kill in emacs mode
+
+lib/readline/search.c
+ - noninc_search saves and restores the mark, since it can be changed
+ while reading the search string
+ - noninc_dosearch sets the mark at the end of the line, making the
+ region bound the `inserted' text since rl_point is set to 0
+ - rl_history_search_internal sets the mark at the end of the line,
+ for the same reason
+
+lib/readline/isearch.c
+ - rl_search_history now saves and restores the mark
+ - if no matching lines are found at all when doing an isearch, leave
+ point where it was instead of moving it to the end of the line
+
+ 12/17
+ -----
+lib/readline/rlmbutil.h
+ - new file, place for multi-byte character defines and extern

+
+lib/readline/readline.h
+ - include rltypedefs.h
+
+ 12/19
+ -----
+lib/readline/complete.c
+ - slight change to mark-directories code to avoid adding a slash if
+ point is at the end of the line (rl_line_buffer[rl_point] == '\0')
+ and the previous character was a slash
+ - change printable_part to not return empty pathnames, which could
+ happen when completing filenames and a filename with a trailing
+ slash was passed as the argument. If the portion following the
+ trailing slash is NULL, ignore it and look for a previous slash.
+ If there's no previous slash, just return the filename argument
+ - new variable, rl_completion_mark_symlink_dirs, mirrors the value
+ of (user-settable with a variable) _rl_complete_mark_symlink_dirs
+ but may be modified by application-specific completion functions
+ when appropriate (set in rl_complete_internal and rl_menu_complete)
+
+lib/readline/readline.h
+ - extern declaration for rl_completion_mark_symlink_dirs
+
+pcomplete.c
+ - if one of the actions is CA_DIRECTORY, set

+
+lib/readline/doc/rltech.texinfo
+ - documented rl_completion_mark_symlink_dirs variable
+
+lib/readline/doc/rluser.texinfo, doc/bash.1

+
+builtins/enable.def
+ - changed enable_shell_builtin to disallow enabling disabled

+doc/Makefile.in
+ - new rule to make an `RBASH' file documenting the restrictions
+ imposed by a restricted shell
+
+expr.c
+ - broke the code that evaluates variables and returns results out
+ of readtok() into a new function: expr_streval()
+ - expr_streval() now performs the standard unset variable error
+ behavior if `set -u' has been executed and it's asked to look
+ up an unset variable
+ - broke the code that frees up the expression context stack into
+ a new function: expr_unwind()
+
+variables.c
+ - fixed bind_int_variable so it handles array element assignment,
+ so expressions like `b[7]++' and `b[0] = 42' work right
+ - new function, get_variable_value, returns the string value of
+ the SHELL_VAR * passed as an argument
+ - get_string_value now calls get_variable_value with a non-null
+ result from find_variable
+
+ 12/20

+lib/tilde/tilde.h
+ - header files should not include <config.h>
+
+parse.y
+ - replace code in decode_prompt_string that chops up value returned
+ by ctime(3) with calls to strftime -- as a result, the expansion
+ of \@ has changed slightly (since it depends on the locale)
+ - added new \D{format} prompt string escape; `format' is passed to
+ strftime(3). Empty format is the same as `%X' (locale-specific
+ representation of the current time)
+ - combined cases for '\\', '\a', '\e', and '\r' in same case branch
+ in decode_prompt_string
+
+doc/{bash.1,bashref.texi}

+
+ 12/27

+ o in _rl_overwrite_char, do the insert before the delete so
+ that an undo positions the cursor on the character restored,
+ not to the right of it

+ - change prepare_terminal_settings so that it can track changes to the

+This is a terse description of the new features added to bash-3.0 since
+the release of bash-2.05b. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. ANSI string expansion now implements the \x{hexdigits} escape.
+
+b. There is a new loadable `strftime' builtin.
+
+c. New variable, COMP_WORDBREAKS, which controls the readline completer's
+ idea of word break characters.
+
+d. The `type' builtin no longer reports on aliases unless alias expansion
+ will actually be performed.
+
+e. HISTCONTROL is now a colon-separated list of values, which permits
+ more extensibility and backwards compatibility.
+
+f. HISTCONTROL may now include the `erasedups' option, which causes all lines
+ matching a line being added to be removed from the history list.
+
+g. `configure' has a new `--enable-multibyte' argument that permits multibyte
+ character support to be disabled even on systems that support it.
+
+h. New variables to support the bash debugger: BASH_ARGC, BASH_ARGV,
+ BASH_SOURCE, BASH_LINENO, BASH_SUBSHELL, BASH_EXECUTION_STRING,
+ BASH_COMMAND
+
+i. FUNCNAME has been changed to support the debugger: it's now an array
+ variable.
+
+j. for, case, select, arithmetic commands now keep line number information
+ for the debugger.
+
+k. There is a new `RETURN' trap executed when a function or sourced script
+ returns (not inherited child processes; inherited by command substitution
+ if function tracing is enabled and the debugger is active).
+
+l. New invocation option: --debugger. Enables debugging and turns on new
+ `extdebug' shell option.
+
+m. New `functrace' and `errtrace' options to `set -o' cause DEBUG and ERR
+ traps, respectively, to be inherited by shell functions. Equivalent to
+ `set -T' and `set -E' respectively. The `functrace' option also controls
+ whether or not the DEBUG trap is inherited by sourced scripts.
+
+n. The DEBUG trap is run before binding the variable and running the action
+ list in a `for' command, binding the selection variable and running the
+ query in a `select' command, and before attempting a match in a `case'
+ command.
+
+o. New `--enable-debugger' option to `configure' to compile in the debugger
+ support code.
+
+p. `declare -F' now prints out extra line number and source file information
+ if the `extdebug' option is set.
+
+q. If `extdebug' is enabled, a non-zero return value from a DEBUG trap causes
+ the next command to be skipped, and a return value of 2 while in a
+ function or sourced script forces a `return'.
+
+r. New `caller' builtin to provide a call stack for the bash debugger.
+
+s. The DEBUG trap is run just before the first command in a function body is
+ executed, for the debugger.
+
+t. `for', `select', and `case' command heads are printed when `set -x' is
+ enabled.
+
+u. There is a new {x..y} brace expansion, which is shorthand for {x.x+1,
+ x+2,...,y}. x and y can be integers or single characters; the sequence
+ may ascend or descend; the increment is always 1.
+
+v. New ksh93-like ${!array[@]} expansion, expands to all the keys (indices)
+ of array.
+
+w. New `force_fignore' shopt option; if enabled, suffixes specified by
+ FIGNORE cause words to be ignored when performing word completion even
+ if they're the only possibilities.
+
+x. New `gnu_errfmt' shopt option; if enabled, error messages follow the `gnu
+ style' (filename:lineno:message) format.
+
+y. New `-o bashdefault' option to complete and compgen; if set, causes the
+ whole set of bash completions to be performed if the compspec doesn't
+ result in a match.
+
+z. New `-o plusdirs' option to complete and compgen; if set, causes directory
+ name completion to be performed and the results added to the rest of the
+ possible completions.
+
+aa. `kill' is available as a builtin even when the shell is built without
+ job control.
+
+bb. New HISTTIMEFORMAT variable; value is a format string to pass to
+ strftime(3). If set and not null, the `history' builtin prints out
+ timestamp information according to the specified format when displaying
+ history entries. If set, bash tells the history library to write out
+ timestamp information when the history file is written.
+
+cc. The [[ ... ]] command has a new binary `=~' operator that performs
+ extended regular expression (egrep-like) matching.
+
+dd. `configure' has a new `--enable-cond-regexp' option (enabled by default)
+ to enable the =~ operator and regexp matching in [[ ... ]].
+
+ee. Subexpressions matched by the =~ operator are placed in the new
+ BASH_REMATCH array variable.
+
+ff. New `failglob' option that causes an expansion error when pathname
+ expansion fails to produce a match.
+
+gg. New `set -o pipefail' option that causes a pipeline to return a failure
+ status if any of the processes in the pipeline fail, not just the last
+ one.
+
+2. New Features in Readline
+
+a. History expansion has a new `a' modifier equivalent to the `g' modifier
+ for compatibility with the BSD csh.
+
+b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
+ modifier, which performs a substitution once per word.
+
+c. All non-incremental search operations may now undo the operation of
+ replacing the current line with the history line.
+
+d. The text inserted by an `a' command in vi mode can be reinserted with
+ `.'.
+
+e. New bindable variable, `show-all-if-unmodified'. If set, the readline
+ completer will list possible completions immediately if there is more
+ than one completion and partial completion cannot be performed.
+
+f. There is a new application-callable `free_history_entry()' function.
+
+g. History list entries now contain timestamp information; the history file
+ functions know how to read and write timestamp information associated
+ with each entry.
+
+h. Four new key binding functions have been added:
+
+ rl_bind_key_if_unbound()
+ rl_bind_key_if_unbound_in_map()
+ rl_bind_keyseq_if_unbound()
+ rl_bind_keyseq_if_unbound_in_map()
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05b since
+the release of bash-2.05a. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. If set, TMOUT is the default timeout for the `read' builtin.
+
+b. `type' has two new options: `-f' suppresses shell function lookup, and
+ `-P' forces a $PATH search.
+
+c. New code to handle multibyte characters.
+
+d. `select' was changed to be more ksh-compatible, in that the menu is
+ reprinted each time through the loop only if REPLY is set to NULL.
+ The previous behavior is available as a compile-time option.
+
+e. `complete -d' and `complete -o dirnames' now force a slash to be
+ appended to names which are symlinks to directories.
+
+f. There is now a bindable edit-and-execute-command readline command,
+ like the vi-mode `v' command, bound to C-xC-e in emacs mode.
+
+g. Added support for ksh93-like [:word:] character class in pattern matching.
+
+h. The $'...' quoting construct now expands \cX to Control-X.
+
+i. A new \D{...} prompt expansion; passes the `...' to strftime and inserts
+ the result into the expanded prompt.
+
+j. The shell now performs arithmetic in the largest integer size the
+ machine supports (intmax_t), instead of long.
+
+k. If a numeric argument is supplied to one of the bash globbing completion
+ functions, a `*' is appended to the word before expansion is attempted.
+
+l. The bash globbing completion functions now allow completions to be listed
+ with double tabs or if `show-all-if-ambiguous' is set.
+
+m. New `-o nospace' option for `complete' and `compgen' builtins; suppresses
+ readline's appending a space to the completed word.
+
+n. New `here-string' redirection operator: <<< word.
+
+o. When displaying variables, function attributes and definitions are shown
+ separately, allowing them to be re-used as input (attempting to re-use
+ the old output would result in syntax errors).
+
+p. There is a new configuration option `--enable-mem-scramble', controls
+ bash malloc behavior of writing garbage characters into memory at
+ allocation and free time.
+
+q. The `complete' and `compgen' builtins now have a new `-s/-A service'
+ option to complete on names from /etc/services.
+
+r. `read' has a new `-u fd' option to read from a specified file descriptor.
+
+s. Fix the completion code so that expansion errors in a directory name
+ don't cause a longjmp back to the command loop.
+
+t. Fixed word completion inside command substitution to work a little more
+ intuitively.
+
+u. The `printf' %q format specifier now uses $'...' quoting to print the
+ argument if it contains non-printing characters.
+
+v. The `declare' and `typeset' builtins have a new `-t' option. When applied
+ to functions, it causes the DEBUG trap to be inherited by the named
+ function. Currently has no effect on variables.
+
+w. The DEBUG trap is now run *before* simple commands, ((...)) commands,
+ [[...]] conditional commands, and for ((...)) loops.
+
+x. The expansion of $LINENO inside a shell function is only relative to the
+ function start if the shell is interactive -- if the shell is running a
+ script, $LINENO expands to the line number in the script. This is as
+ POSIX-2001 requires.
+
+y. The bash debugger in examples/bashdb has been modified to work with the
+ new DEBUG trap semantics, the command set has been made more gdb-like,
+ and the changes to $LINENO make debugging functions work better. Code
+ from Gary Vaughan.
+
+z. New [n]<&word- and [n]>&word- redirections from ksh93 -- move fds (dup
+ and close).
+
+aa. There is a new `-l' invocation option, equivalent to `--login'.
+
+bb. The `hash' builtin has a new `-l' option to list contents in a reusable
+ format, and a `-d' option to remove a name from the hash table.
+
+cc. There is now support for placing the long help text into separate files
+ installed into ${datadir}/bash. Not enabled by default; can be turned
+ on with `--enable-separate-helpfiles' option to configure.
+
+dd. All builtins that take operands accept a `--' pseudo-option, except
+ `echo'.
+
+ee. The `echo' builtin now accepts \0xxx (zero to three octal digits following
+ the `0') in addition to \xxx (one to three octal digits) for SUSv3/XPG6/
+ POSIX.1-2001 compliance.
+
+
+2. New Features in Readline
+
+a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
+ be bound to readline functions. Now the arrow keys may be used in vi
+ insert mode.
+
+b. When listing completions, and the number of lines displayed is more than
+ the screen length, readline uses an internal pager to display the results.
+ This is controlled by the `page-completions' variable (default on).
+
+c. New code to handle editing and displaying multibyte characters.
+
+d. The behavior introduced in bash-2.05a of deciding whether or not to
+ append a slash to a completed name that is a symlink to a directory has
+ been made optional, controlled by the `mark-symlinked-directories'
+ variable (default is the 2.05a behavior).
+
+e. The `insert-comment' command now acts as a toggle if given a numeric
+ argument: if the first characters on the line don't specify a
+ comment, insert one; if they do, delete the comment text
+
+f. New application-settable completion variable:
+ rl_completion_mark_symlink_dirs, allows an application's completion
+ function to temporarily override the user's preference for appending
+ slashes to names which are symlinks to directories.
+
+g. New function available to application completion functions:
+ rl_completion_mode, to tell how the completion function was invoked
+ and decide which argument to supply to rl_complete_internal (to list
+ completions, etc.).
+
+h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
+ bindable command, which could be bound to `Insert'.
+
+i. New application-settable completion variable:
+ rl_completion_suppress_append, inhibits appending of
+ rl_completion_append_character to completed words.
+
+j. New key bindings when reading an incremental search string: ^W yanks
+ the currently-matched word out of the current line into the search
+ string; ^Y yanks the rest of the current line into the search string,
+ DEL or ^H deletes characters from the search string.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05a since
+the release of bash-2.05. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Added support for DESTDIR installation root prefix, so you can do a
+ `make install DESTDIR=bash-root' and do easier binary packaging.
+
+b. Added support for builtin printf "'" flag character as per latest POSIX
+ drafts.
+
+c. Support for POSIX.2 printf(1) length specifiers `j', `t', and `z' (from
+ ISO C99).
+
+d. New autoconf macro, RL_LIB_READLINE_VERSION, for use by other applications
+ (bash doesn't use very much of what it returns).
+
+e. `set [-+]o nolog' is recognized as required by the latest POSIX drafts,
+ but ignored.
+
+f. New read-only `shopt' option: login_shell. Set to non-zero value if the
+ shell is a login shell.
+
+g. New `\A' prompt string escape sequence; expands to time in 24 HH:MM format.
+
+h. New `-A group/-g' option to complete and compgen; does group name
+ completion.
+
+i. New `-t' option to `hash' to list hash values for each filename argument.
+
+j. New [-+]O invocation option to set and unset `shopt' options at startup.
+
+k. configure's `--with-installed-readline' option now takes an optional
+ `=PATH' suffix to set the root of the tree where readline is installed
+ to PATH.
+
+l. The ksh-like `ERR' trap has been added. The `ERR' trap will be run
+ whenever the shell would have exited if the -e option were enabled.
+ It is not inherited by shell functions.
+
+m. `readonly', `export', and `declare' now print variables which have been
+ given attributes but not set by assigning a value as just a command and
+ a variable name (like `export foo') when listing, as the latest POSIX
+ drafts require.
+
+n. `bashbug' now requires that the subject be changed from the default.
+
+o. configure has a new `--enable-largefile' option, like other GNU utilities.
+
+p. `for' loops now allow empty word lists after `in', like the latest POSIX
+ drafts require.
+
+q. The builtin `ulimit' now takes two new non-numeric arguments: `hard',
+ meaning the current hard limit, and `soft', meaning the current soft
+ limit, in addition to `unlimited'
+
+r. `ulimit' now prints the option letter associated with a particular
+ resource when printing more than one limit.
+
+s. `ulimit' prints `hard' or `soft' when a value is not `unlimited' but is
+ one of RLIM_SAVED_MAX or RLIM_SAVED_CUR, respectively.
+
+t. The `printf' builtin now handles the %a and %A conversions if they're
+ implemented by printf(3).
+
+u. The `printf' builtin now handles the %F conversion (just about like %f).
+
+v. The `printf' builtin now handles the %n conversion like printf(3). The
+ corresponding argument is the name of a shell variable to which the
+ value is assigned.
+
+2. New Features in Readline
+
+a. Added extern declaration for rl_get_termcap to readline.h, making it a
+ public function (it was always there, just not in readline.h).
+
+b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
+ RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
+
+c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
+
+d. New bindable boolean readline variable: match-hidden-files. Controls
+ completion of files beginning with a `.' (on Unix). Enabled by default.
+
+e. The history expansion code now allows any character to terminate a
+ `:first-' modifier, like csh.
+
+f. New bindable variable `history-preserve-point'. If set, the history
+ code attempts to place the user at the same location on each history
+ line retrived with previous-history or next-history.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.05 since
+the release of bash-2.04. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. Added a new `--init-file' invocation argument as a synonym for `--rcfile',
+ per the new GNU coding standards.
+
+b. The /dev/tcp and /dev/udp redirections now accept service names as well as
+ port numbers.
+
+c. `complete' and `compgen' now take a `-o value' option, which controls some
+ of the aspects of that compspec. Valid values are:
+
+ default - perform bash default completion if programmable
+ completion produces no matches
+ dirnames - perform directory name completion if programmable
+ completion produces no matches
+ filenames - tell readline that the compspec produces filenames,
+ so it can do things like append slashes to
+ directory names and suppress trailing spaces
+
+d. A new loadable builtin, realpath, which canonicalizes and expands symlinks
+ in pathname arguments.
+
+e. When `set' is called without options, it prints function defintions in a
+ way that allows them to be reused as input. This affects `declare' and
+ `declare -p' as well. This only happens when the shell is not in POSIX
+ mode, since POSIX.2 forbids this behavior.
+
+f. Bash-2.05 once again honors the current locale setting when processing
+ ranges within pattern matching bracket expressions (e.g., [A-Z]).
+
+2. New Features in Readline
+
+a. The blink timeout for paren matching is now settable by applications,
+ via the rl_set_paren_blink_timeout() function.
+
+b. _rl_executing_macro has been renamed to rl_executing_macro, which means
+ it's now part of the public interface.
+
+c. Readline has a new variable, rl_readline_state, which is a bitmap that
+ encapsulates the current state of the library; intended for use by
+ callbacks and hook functions.
+
+d. New application-callable function rl_set_prompt(const char *prompt):
+ expands its prompt string argument and sets rl_prompt to the result.
+
+e. New application-callable function rl_set_screen_size(int rows, int cols):
+ public method for applications to set readline's idea of the screen
+ dimensions.
+
+f. New function, rl_get_screen_size (int *rows, int *columns), returns
+ readline's idea of the screen dimensions.
+
+g. The timeout in rl_gather_tyi (readline keyboard input polling function)
+ is now settable via a function (rl_set_keyboard_input_timeout()).
+
+h. Renamed the max_input_history variable to history_max_entries; the old
+ variable is maintained for backwards compatibility.
+
+i. The list of characters that separate words for the history tokenizer is
+ now settable with a variable: history_word_delimiters. The default
+ value is as before.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.04 since
+the release of bash-2.03. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. The history builtin has a `-d offset' option to delete the history entry
+ at position `offset'.
+
+b. The prompt expansion code has two new escape sequences: \j, the number of
+ active jobs; and \l, the basename of the shell's tty device name.
+
+c. The `bind' builtin has a new `-x' option to bind key sequences to shell
+ commands.
+
+d. There is a new shell option, no_empty_command_completion, which, when
+ enabled, disables command completion when TAB is typed on an empty line.
+
+e. The `help' builtin has a `-s' option to just print a builtin's usage
+ synopsis.
+
+f. There are several new arithmetic operators: id++, id-- (variable
+ post-increment/decrement), ++id, --id (variable pre-increment/decrement),
+ expr1 , expr2 (comma operator).
+
+g. There is a new ksh-93 style arithmetic for command:
+ for ((expr1 ; expr2; expr3 )); do list; done
+
+h. The `read' builtin has a number of new options:
+ -t timeout only wait timeout seconds for input
+ -n nchars only read nchars from input instead of a full line
+ -d delim read until delim rather than newline
+ -s don't echo input chars as they are read
+
+i. The redirection code now handles several filenames specially:
+ /dev/fd/N, /dev/stdin, /dev/stdout, and /dev/stderr, whether or
+ not they are present in the file system.
+
+j. The redirection code now recognizes pathnames of the form
+ /dev/tcp/host/port and /dev/udp/host/port, and tries to open a socket
+ of the appropriate type to the specified port on the specified host.
+
+k. The ksh-93 ${!prefix*} expansion, which expands to the names of all
+ shell variables with prefix PREFIX, has been implemented.
+
+l. There is a new dynamic variable, FUNCNAME, which expands to the name of
+ a currently-executing function. Assignments to FUNCNAME have no effect.
+
+m. The GROUPS variable is no longer readonly; assignments to it are silently
+ discarded. This means it can be unset.
+
+n. A new programmable completion facility, with two new builtin commands:
+ complete and compgen.
+
+o. configure has a new option, `--enable-progcomp', to compile in the
+ programmable completion features (enabled by default).
+
+p. `shopt' has a new option, `progcomp', to enable and disable programmable
+ completion at runtime.
+
+q. Unsetting HOSTFILE now clears the list of hostnames used for completion.
+
+r. configure has a new option, `--enable-bash-malloc', replacing the old
+ `--with-gnu-malloc' (which is still present for backwards compatibility).
+
+s. There is a new manual page describing rbash, the restricted shell.
+
+t. `bashbug' has new `--help' and `--version' options.
+
+u. `shopt' has a new `xpg_echo' option, which controls the behavior of
+ `echo' with respect to backslash-escaped characters at runtime.
+
+v. If NON_INTERACTIVE_LOGIN_SHELLS is defined, all login shells read the
+ startup files, even if they are not interactive.
+
+w. The LC_NUMERIC variable is now treated specially, and used to set the
+ LC_NUMERIC locale category for number formatting, e.g., when `printf'
+ displays floating-point numbers.
+
+2. New features in Readline
+
+a. Parentheses matching is now always compiled into readline, and enabled
+ or disabled when the value of the `blink-matching-paren' variable is
+ changed.
+
+b. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+c. MS-DOS systems now use ~/_history as the default history file.
+
+d. history-search-{forward,backward} now leave the point at the end of the
+ line when the string to search for is empty, like
+ {reverse,forward}-search-history.
+
+e. history-search-{forward,backward} now leave the last history line found
+ in the readline buffer if the second or subsequent search fails.
+
+f. New function for use by applications: rl_on_new_line_with_prompt, used
+ when an application displays the prompt itself before calling readline().
+
+g. New variable for use by applications: rl_already_prompted. An application
+ that displays the prompt itself before calling readline() must set this to
+ a non-zero value.
+
+h. A new variable, rl_gnu_readline_p, always 1. The intent is that an
+ application can verify whether or not it is linked with the `real'
+ readline library or some substitute.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.03 since
+the release of bash-2.02. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. New `shopt' option, `restricted_shell', indicating whether or not the
+ shell was started in restricted mode, for use in startup files.
+
+b. Filename generation is now performed on the words between ( and ) in
+ array assignments (which it probably should have done all along).
+
+c. OLDPWD is now auto-exported, as POSIX.2 seems to require.
+
+d. ENV and BASH_ENV are read-only variables in a restricted shell.
+
+e. A change was made to the startup file code so that any shell begun with
+ the `--login' option, even non-interactive shells, will source the login
+ shell startup files.
+
+2. New Features in Readline
+
+a. Many changes to the signal handling:
+ o Readline now catches SIGQUIT and cleans up the tty before returning;
+ o A new variable, rl_catch_signals, is available to application writers
+ to indicate to readline whether or not it should install its own
+ signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
+ SIGTTIN, and SIGTTOU;
+ o A new variable, rl_catch_sigwinch, is available to application
+ writers to indicate to readline whether or not it should install its
+ own signal handler for SIGWINCH, which will chain to the calling
+ applications's SIGWINCH handler, if one is installed;
+ o There is a new function, rl_free_line_state, for application signal
+ handlers to call to free up the state associated with the current
+ line after receiving a signal;
+ o There is a new function, rl_cleanup_after_signal, to clean up the
+ display and terminal state after receiving a signal;
+ o There is a new function, rl_reset_after_signal, to reinitialize the
+ terminal and display state after an application signal handler
+ returns and readline continues
+
+b. There is a new function, rl_resize_terminal, to reset readline's idea of
+ the screen size after a SIGWINCH.
+
+c. New public functions: rl_save_prompt and rl_restore_prompt. These were
+ previously private functions with a `_' prefix.
+
+d. New function hook: rl_pre_input_hook, called just before readline starts
+ reading input, after initialization.
+
+e. New function hook: rl_display_matches_hook, called when readline would
+ display the list of completion matches. The new function
+ rl_display_match_list is what readline uses internally, and is available
+ for use by application functions called via this hook.
+
+f. New bindable function, delete-char-or-list, like tcsh.
+
+g. A new variable, rl_erase_empty_line, which, if set by an application using
+ readline, will cause readline to erase, prompt and all, lines on which the
+ only thing typed was a newline.
+
+h. New bindable variable: `isearch-terminators'.
+
+i. New bindable function: `forward-backward-delete-char' (unbound by default).
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.02 since
+the release of bash-2.01.1. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. A new version of malloc, based on the older GNU malloc, that has many
+ changes, is more page-based, is more conservative with memory usage,
+ and does not `orphan' large blocks when they are freed.
+
+b. A new version of gmalloc, based on the old GLIBC malloc, with many
+ changes and range checking included by default.
+
+c. A new implementation of fnmatch(3) that includes full POSIX.2 Basic
+ Regular Expression matching, including character classes, collating
+ symbols, equivalence classes, and support for case-insensitive pattern
+ matching.
+
+d. ksh-88 egrep-style extended pattern matching ([@+*?!](patlist)) has been
+ implemented, controlled by a new `shopt' option, `extglob'.
+
+e. There is a new ksh-like `[[' compound command, which implements
+ extended `test' functionality.
+
+f. There is a new `printf' builtin, implemented according to the POSIX.2
+ specification.
+
+g. There is a new feature for command substitution: $(< filename) now expands
+ to the contents of `filename', with any trailing newlines removed
+ (equivalent to $(cat filename)).
+
+h. There are new tilde prefixes which expand to directories from the
+ directory stack.
+
+i. There is a new `**' arithmetic operator to do exponentiation.
+
+j. There are new configuration options to control how bash is linked:
+ `--enable-profiling', to allow bash to be profiled with gprof, and
+ `--enable-static-link', to allow bash to be linked statically.
+
+k. There is a new configuration option, `--enable-cond-command', which
+ controls whether or not the `[[' command is included. It is on by
+ default.
+
+l. There is a new configuration option, `--enable-extended-glob', which
+ controls whether or not the ksh extended globbing feature is included.
+ It is enabled by default.
+
+m. There is a new configuration #define in config.h.top that, when enabled,
+ will cause all login shells to source /etc/profile and one of the user-
+ specific login shell startup files, whether or not the shell is
+ interactive.
+
+n. There is a new invocation option, `--dump-po-strings', to dump
+ a shell script's translatable strings ($"...") in GNU `po' format.
+
+o. There is a new `shopt' option, `nocaseglob', to enable case-insensitive
+ pattern matching when globbing filenames and using the `case' construct.
+
+p. There is a new `shopt' option, `huponexit', which, when enabled, causes
+ the shell to send SIGHUP to all jobs when an interactive login shell
+ exits.
+
+q. `bind' has a new `-u' option, which takes a readline function name as an
+ argument and unbinds all key sequences bound to that function in a
+ specified keymap.
+
+r. `disown' now has `-a' and `-r' options, to limit operation to all jobs
+ and running jobs, respectively.
+
+s. The `shopt' `-p' option now causes output to be displayed in a reusable
+ format.
+
+t. `test' has a new `-N' option, which returns true if the filename argument
+ has been modified since it was last accessed.
+
+u. `umask' now has a `-p' option to print output in a reusable format.
+
+v. A new escape sequence, `\xNNN', has been added to the `echo -e' and $'...'
+ translation code. It expands to the character whose ascii code is NNN
+ in hexadecimal.
+
+w. The prompt string expansion code has a new `\r' escape sequence.
+
+x. The shell may now be cross-compiled for the CYGWIN32 environment on
+ a Unix machine.
+
+2. New Features in Readline
+
+a. There is now an option for `iterative' yank-last-arg handline, so a user
+ can keep entering `M-.', yanking the last argument of successive history
+ lines.
+
+b. New variable, `print-completions-horizontally', which causes completion
+ matches to be displayed across the screen (like `ls -x') rather than up
+ and down the screen (like `ls').
+
+c. New variable, `completion-ignore-case', which causes filename completion
+ and matching to be performed case-insensitively.
+
+d. There is a new bindable command, `magic-space', which causes history
+ expansion to be performed on the current readline buffer and a space to
+ be inserted into the result.
+
+e. There is a new bindable command, `menu-complete', which enables tcsh-like
+ menu completion (successive executions of menu-complete insert a single
+ completion match, cycling through the list of possible completions).
+
+f. There is a new bindable command, `paste-from-clipboard', for use on Win32
+ systems, to insert the text from the Win32 clipboard into the editing
+ buffer.
+
+g. The key sequence translation code now understands printf-style backslash
+ escape sequences, including \NNN octal escapes. These escape sequences
+ may be used in key sequence definitions or macro values.
+
+h. An `$include' inputrc file parser directive has been added.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.01 since
+the release of bash-2.0. As always, the manual page (doc/bash.1) is the
+place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. There is a new builtin array variable: GROUPS, the set of groups to which
+ the user belongs. This is used by the test suite.
+
+2. New Features in Readline
+
+a. If a key sequence bound to `universal-argument' is read while reading a
+ numeric argument started with `universal-argument', it terminates the
+ argument but is otherwise ignored. This provides a way to insert multiple
+ instances of a digit string, and is how GNU emacs does it.
+
+-------------------------------------------------------------------------------
+This is a terse description of the new features added to bash-2.0 since
+the release of bash-1.14.7. As always, the manual page (doc/bash.1) is
+the place to look for complete descriptions.
+
+1. New Features in Bash
+
+a. There is a new invocation option, -D, that dumps translatable strings
+ in a script.
+
+b. The `long' invocation options must now be prefixed with `--'.
+
+c. New long invocation options: --dump-strings, --help, --verbose
+
+d. The `nolineediting' invocation option was renamed to `noediting'.
+
+e. The `nobraceexpansion' and `quiet' long invocation options were removed.
+
+f. The `--help' and `--version' long options now work as the GNU coding
+ standards specify.
+
+g. If invoked as `sh', bash now enters posix mode after reading the
+ startup files, and reads and executes commands from the file named
+ by $ENV if interactive (as POSIX.2 specifies). A login shell invoked
+ as `sh' reads $ENV after /etc/profile and ~/.profile.
+
+h. There is a new reserved word, `time', for timing pipelines, builtin
+ commands, and shell functions. It uses the value of the TIMEFORMAT
+ variable as a format string describing how to print the timing
+ statistics.
+
+i. The $'...' quoting syntax expands ANSI-C escapes in ... and leaves the
+ result single-quoted.
+
+j. The $"..." quoting syntax performs locale-specific translation of ...
+ and leaves the result double-quoted.
+
+k. LINENO now works correctly in functions.
+
+l. New variables: DIRSTACK, PIPESTATUS, BASH_VERSINFO, HOSTNAME, SHELLOPTS,
+ MACHTYPE. The first three are array variables.
+
+m. The BASH_VERSION and BASH_VERSINFO variables now include the shell's
+ `release status' (alpha[N], beta[N], release).
+
+n. Some variables have been removed: MAIL_WARNING, notify, history_control,
+ command_oriented_history, glob_dot_filenames, allow_null_glob_expansion,
+ nolinks, hostname_completion_file, noclobber, no_exit_on_failed_exec, and
+ cdable_vars. Most of them are now implemented with the new `shopt'
+ builtin; others were already implemented by `set'.
+
+o. Bash now uses some new variables: LC_ALL, LC_MESSAGES, LC_CTYPE,
+ LC_COLLATE, LANG, GLOBIGNORE, HISTIGNORE.
+
+p. The shell now supports integer-indexed arrays of unlimited length,
+ with a new compound assignment syntax and changes to the appropriate
+ builtin commands (declare/typeset, read, readonly, etc.). The array
+ index may be an arithmetic expression.
+
+q. ${!var}: indirect variable expansion, equivalent to eval \${$var}.
+
+r. ${paramter:offset[:length]}: variable substring extraction.
+
+s. ${parameter/pattern[/[/]string]}: variable pattern substitution.
+
+t. The $[...] arithmetic expansion syntax is no longer supported, in
+ favor of $((...)).
+
+u. Aliases can now be expanded in shell scripts with a shell option
+ (shopt expand_aliases).
+
+v. History and history expansion can now be used in scripts with
+ set -o history and set -H.
+
+w. All builtins now return an exit status of 2 for incorrect usage.
+
+x. Interactive shells resend SIGHUP to all running or stopped children
+ if (and only if) they exit due to a SIGHUP.
+
+y. New prompting expansions: \a, \e, \H, \T, \@, \v, \V.
+
+z. Variable expansion in prompt strings is now controllable via a shell
+ option (shopt promptvars).
+
+aa. Bash now defaults to using command-oriented history.
+
+bb. The history file ($HISTFILE) is now truncated to $HISTFILESIZE after
+ being written.
+
+cc. The POSIX.2 conditional arithmetic evaluation syntax (expr ? expr : expr)
+ has been implemented.
+
+dd. Each builtin now accepts `--' to signify the end of the options, except
+ as documented (echo, etc.).
+
+ee. All builtins use -p to display values in a re-readable format where
+ appropriate, except as documented (echo, type, etc.).
+
+ff. The `alias' builtin has a new -p option.
+
+gg. Changes to the `bind' builtin:
+ o has new options: -psPSVr.
+ o the `-d' option was renamed to `-p'
+ o the `-v' option now dumps variables; the old `-v' is now `-P'
+
+hh. The `bye' synonym for `exit' was removed.
+
+ii. The -L and -P options to `cd' and `pwd' have been documented.
+
+jj. The `cd' builtin now does spelling correction on the directory name
+ by default. This is settable with a shell option (shopt cdspell).
+
+kk. The `declare' builtin has new options: -a, -F, -p.
+
+ll. The `dirs' builtin has new options: -c, -p, -v.
+
+mm. The new `disown' builtin removes jobs from the shell's jobs table
+ or inhibits the resending of SIGHUP when the shell receives a
+ SIGHUP.
+
+nn. The `echo' builtin has a new escape character: \e.
+
+oo. The `enable' builtin can now load new builtins dynamically from shared
+ objects on systems with the dlopen/dlsym interface. There are a number
+ of examples in the examples/loadables directory. There are also
+ new options: -d, -f, -s, -p.
+
+pp. The `-all' option to `enable' was removed in favor of `-a'.
+
+qq. The `exec' builtin has new options: -l, -c, -a.
+
+rr. The `hash' builtin has a new option: -p.
+
+ss. The `history' builtin has new options: -c, -p, -s.
+
+tt. The `jobs' builtin has new options: -r, -s.
+
+uu. The `kill' builtin has new options: -n signum, -l signame.
+
+vv. The `pushd' and `popd' builtins have a new option: -n.
+
+ww. The `read' builtin has new options: -p prompt, -e, -a.
+
+xx. The `readonly' builtin has a new -a option, and the -n option was removed.
+
+yy. Changes to the `set' builtin:
+ o new options: -B, -o keyword, -o onecmd, -o history
+ o options removed: -l, -d, -o nohash
+ o options changed: +o, -h, -o hashall
+ o now displays variables in a format that can be re-read as input
+
+zz. The new `shopt' builtin controls shell optional behavior previously
+ done by setting and unsetting certain shell variables.
+
+aaa. The `test' builtin has new operators: -o option, s1 == s2, s1 < s2,
+ and s1 > s2, where s1 and s2 are strings.
+
+bbb. There is a new trap, DEBUG, executed after every simple command.
+
+ccc. The `trap' builtin has a new -p option.
+
+ddd. The `ulimit' builtin has a new -l option on 4.4BSD-based systems.
+
+eee. The PS1, PS2, PATH, and IFS variables may now be unset.
+
+fff. The restricted shell mode has been expanded and is now documented.
+
+ggg. Security improvements:
+ o functions are not imported from the environment if running setuid
+ or with -p
+ o no startup files are sourced if running setuid or with -p
+
+hhh. The documentation has been overhauled: the texinfo manual was
+ expanded, and HTML versions of the man page and texinfo manual
+ are included.
+
+iii. Changes to Posix mode:
+ o Command lookup now finds special builtins before shell functions.
+ o Failure of a special builtin causes a non-interactive shell to
+ exit. Failures are defined in the POSIX.2 specification.
+ o If the `cd' builtin finds a directory to change to using $CDPATH,
+ the value assigned to PWD when `cd' completes does not contain
+ any symbolic links.
+ o A non-interactive shell exits if a variable assignment error
+ occurs when no command name follows the assignment statements.
+ o A non-interactive shell exits if the interation variable in a
+ `for' statement or the selection variable in a `select' statement
+ is read-only or another variable assignment error occurs.
+ o The `<>' redirection operator now opens a file for both stdin and
+ stdout by default, not just when in posix mode.
+ o Assignment statements preceding special builtins now persist in
+ the shell's environment when the builtin completes.
+
+ Posix mode is now completely POSIX.2-compliant (modulo bugs). When
+ invoked as sh, bash should be completely POSIX.2-compliant.
+
+jjj. The default value of PS1 is now "\s-\v\$ ".
+
+kkk. The ksh-like ((...)) arithmetic command syntax has been implemented.
+ This is exactly equivalent to `let "..."'.
+
+lll. Integer constants have been extended to base 64.
+
+mmm. The `ulimit' builtin now sets both hard and soft limits and reports the
+ soft limit by default.
+
+2. New Features in Readline
+
+a. New variables: enable-keypad, input-meta (new name for meta-flag),
+ mark-directories, visible-stats (now documented), disable-completion,
+ comment-begin.
+
+b. New bindable commands: kill-region, copy-region-as-kill,
+ copy-backward-word, copy-forward-word, set-mark, exchange-point-and-mark,
+ character-search, character-search-backward, insert-comment,
+ glob-expand-word, glob-list-expansions, dump-variables, dump-macros.
+
+c. New emacs keybindings: delete-horizontal-space (M-\),
+ insert-completions (M-*), possible-completions (M-=).
+
+d. The history-search-backward and history-search-forward commands were
+ modified to be the same as previous-line and next-line if point is at
+ the start of the line.
+
+e. More file types are available for the visible-stats mode.
+
+3. Changes of interest in the Bash implementation
+
+a. There is a new autoconf-based configuration mechanism.
+
+b. More things have been moved from Posix mode to standard shell behavior.
+
+c. The trace output (set -x) now inserts quotes where necessary so it can
+ be reused as input.
+
+d. There is a compile-time option for a system-wide interactive shell
+ startup file (disabled by default).
+
+e. The YACC grammar is smaller and tighter, and all 66 shift-reduce
+ conflicts are gone. Several parsing bugs have been fixed.
+
+f. Builtin option parsing has been regularized (using internal_getopt()),
+ with the exception of `echo', `type', and `set'.
+
+g. Builtins now return standard usage messages constructed from the
+ `short doc' used by the help builtin.
+
+h. Completion now quotes using backslashes by default, but honors
+ user-supplied quotes.
+
+i. The GNU libc malloc is available as a configure-time option.
+
+j. There are more internationalization features; bash uses gettext if
+ it is available. The $"..." translation syntax uses the current
+ locale and gettext.
+
+k. There is better reporting of job termination when the shell is not
+ interactive.
+
+l. The shell is somewhat more efficient: it uses a little less memory and
+ makes fewer system calls.
+
+4. Changes of interest in the Readline implementation
+
+a. There is now support for readline `callback' functions.
+
+b. There is now support for user-supplied input, redisplay, and terminal
+ preparation functions.
+
+c. Most of the shell-specific code in readline has been generalized or
+ removed.
+
+d. Most of the annoying redisplay bugs have been fixed, notably the problems
+ with incremental search and excessive redrawing when special characters
+ appear in the prompt string.
+
+e. There are new library functions and variables available to application
+ writers, most having to do with completion and quoting.
+
+f. The NEWLINE character (^J) is now treated as a search terminator by the
+ incremental search functions.

+Introduction
+============
+
+This is GNU Bash, version 3.0b. Bash is the GNU Project's Bourne
+Again SHell, a complete implementation of the POSIX.2 shell spec,
+but also with interactive command line editing, job control on
+architectures that support it, csh-like features such as history
+substitution and brace expansion, and a slew of other features.
+For more information on the features of Bash that are new to this
+type of shell, see the file `doc/bashref.texi'. There is also a
+large Unix-style man page. The man page is the definitive description
+of the shell's features.
+
+See the file CWRU/POSIX.NOTES for a discussion of how Bash differs
+from the POSIX.2 spec and a description of the Bash `posix mode'.
+
+There are some user-visible incompatibilities between this version
+of Bash and the previous widely-distributed version, bash-1.14.
+For details, see the file COMPAT. The NEWS file tersely lists
+features that are new in this release.
+
+Bash is free software, distributed under the terms of the [GNU]
+General Public License, version 2. For more information, see the
+file COPYING.
+
+A number of frequently-asked questions are answered in the file
+`doc/FAQ'.
+
+To compile Bash, try typing `./configure', then `make'. Bash
+auto-configures the build process, so no further intervention
+should be necessary. Bash builds with `gcc' by default if it is
+available. If you want to use `cc' instead, type
+
+ CC=cc ./configure
+
+if you are using a Bourne-style shell. If you are not, the following
+may work:
+
+ env CC=cc ./configure
+
+Read the file INSTALL in this directory for more information about how
+to customize and control the build process. The file NOTES contains
+platform-specific installation and configuration information.
+
+If you are a csh user and wish to convert your csh aliases to Bash
+aliases, you may wish to use the script `examples/misc/alias-conv.sh'
+as a starting point. The script `examples/misc/cshtobash' is a
+more ambitious script that attempts to do a more complete job.
+
+Reporting Bugs
+==============
+
+Bug reports for bash should be sent to:
+
+ bug-bash@gnu.org
+
+using the `bashbug' program that is built and installed at the same
+time as bash.
+
+The discussion list `bug-bash@gnu.org' often contains information
+about new ports of Bash, or discussions of new features or behavior
+changes that people would like. This mailing list is also available
+as a usenet newsgroup: gnu.bash.bug.
+
+When you send a bug report, please use the `bashbug' program that is
+built at the same time as bash. If bash fails to build, try building
+bashbug directly with `make bashbug'. If you cannot build `bashbug',
+please send mail to bug-bash@gnu.org with the following information:
+
+ * the version number and release status of Bash (e.g., 2.05a-release)
+ * the machine and OS that it is running on (you may run
+ `bashversion -l' from the bash build directory for this information)
+ * a list of the compilation flags or the contents of `config.h', if
+ appropriate
+ * a description of the bug
+ * a recipe for recreating the bug reliably
+ * a fix for the bug if you have one!
+
+The `bashbug' program includes much of this automatically.
+
+If you would like to contact the Bash maintainers directly, send mail
+to bash-maintainers@gnu.org.
+
+While the Bash maintainers do not promise to fix all bugs, we would
+like this shell to be the best that we can make it.
+
+Enjoy!

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']

+ mmap shared fixed at somewhere currently unmapped
+ mmap shared fixed at somewhere already mapped

+ VM page cache was not coherent with the file system buffer cache
+ like early versions of FreeBSD and possibly contemporary NetBSD.)
+ For shared mappings, we should conversely verify that changes get
+ propagated back to all the places they're supposed to be.
+
+ Grep wants private fixed already mapped.
+ The main things grep needs to know about mmap are:
+ * does it exist and is it safe to write into the mmap'd area

+ Here is a matrix of mmap possibilities:
+ mmap private not fixed
+ mmap private fixed at somewhere currently unmapped
+ mmap private fixed at somewhere already mapped
+ mmap shared not fixed
+ mmap shared fixed at somewhere currently unmapped
+ mmap shared fixed at somewhere already mapped
+ For private mappings, we should verify that changes cannot be read()
+ back from the file, nor mmap's back from the file at a different
+ address. (There have been systems where private was not correctly
+ implemented like the infamous i386 svr4.0, and systems where the
+ VM page cache was not coherent with the file system buffer cache
+ like early versions of FreeBSD and possibly contemporary NetBSD.)
+ For shared mappings, we should conversely verify that changes get
+ propagated back to all the places they're supposed to be.

Grep wants private fixed already mapped.

Here is a matrix of mmap possibilities:

Grep wants private fixed already mapped.
