Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

Build a copy of + the compressed or uncompressed executable in the same + directory as the executable, as that's less likely to go wrong + if disk space is low. Have the executable exit with status 127, + not 1, if the decompression process fails; this is more compatible + with meta-programs like nohup. Have the executable + uncompress to a temp file with the same basename as the executable; + this is more likely to go right. Fix a race condition where the + executable temporarily did not exist (in either old or new forms). + Check for race conditions better when mv fails. Do not attempt + to use cp to do the real work, only to copy permissions to a temp + file, since we don't want to trash running executables. + +2006-11-26 Paul Eggert + + * inflate.c (inflate_dynamic, inflate): Don't send output to + stderr unless DEBUG is defined and 'verbose'.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..5799d75 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,110 @@ +# Make gzip (GNU zip). + +# Copyright (C) 1999, 2001, 2002, 2006, 2007 Free Software Foundation, Inc. + +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# (at your option) any later version. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Its main advantages over compress are much better +compression and freedom from patented algorithms. The GNU Project +uses it as the standard compression program for its system. + +gzip currently uses by default the LZ77 algorithm used in zip 1.9 (the +portable pkzip compatible archiver). The gzip format was however +designed to accommodate several compression algorithms. See below +for a comparison of zip and gzip. + +gunzip can currently decompress files created by gzip, compress or +pack. The detection of the input format is automatic. For the +gzip format, gunzip checks a 32 bit CRC. For pack, gunzip checks the +uncompressed length. The 'compress' format was not designed to allow +consistency checks. However gunzip is sometimes able to detect a bad +.Z file because there is some redundancy in the .Z compression format. +If you get an error when uncompressing a .Z file, do not assume that +the .Z file is correct simply because the standard uncompress does not +complain. This generally means that the standard uncompress does not +check its input, and happily generates garbage output. + +gzip produces files with a .gz extension. Previous versions of gzip +used the .z extension, which was already used by the 'pack' +Huffman encoder. gunzip is able to decompress .z files (packed +or gzip'ed). + +Several planned features are not yet supported (see the file TODO). +See the file NEWS for a summary of changes since 0.5. See the file +INSTALL for installation instructions. Some answers to frequently +asked questions are given in the file INSTALL, please read it. (In +particular, please don't ask me once more for an /etc/magic entry.) + +WARNING: gzip is sensitive to compiler bugs, particularly when +optimizing. Use "make check" to check that gzip was compiled +correctly. Try compiling gzip without any optimization if you have a +problem. + +Please send all comments and bug reports by electronic mail to +. + +Bug reports should ideally include: + + * The complete output of "gzip -V" (or the contents of revision.h + if you can't get gzip to compile) + * The hardware and operating system (try "uname -a") + * The compiler used to compile (if it is gcc, use "gcc -v") + * A description of the bug behavior + * The input to gzip, that triggered the bug + +If you send me patches for machines I don't have access to, please test them +very carefully. gzip is used for backups, it must be extremely reliable. + +GNU tar 1.11.2 has a -z option to invoke directly gzip, so you don't have to +patch it. The package ftp.uu.net:/languages/emacs-lisp/misc/jka-compr19.el.Z +also supports gzip'ed files. + +The znew and gzexe shell scripts provided with gzip benefit from +(but do not require) the cpmod utility to transfer file attributes. +It is available in +ftp://gatekeeper.dec.com/pub/usenet/comp.sources.unix/volume11/cpmod.Z. + +The sample programs zread.c, sub.c and add.c in subdirectory sample +are provided as examples of useful complements to gzip.

A PRIMOS executable is available +in ftp://ftp.lysator.liu.se/pub/primos/run/gzip.run. + +Some ftp servers can automatically make a tar.Z from a tar file. If +you are getting gzip for the first time, you can ask for a tar.Z file +instead of the much larger tar file. + +Many thanks to those who provided me with bug reports and feedback. +See the files THANKS and ChangeLog for more details. + + + Note about zip vs. gzip: + +The name 'gzip' was a very unfortunate choice, because zip and gzip +are two really different programs, although the actual compression and +decompression sources were written by the same persons. A different +name should have been used for gzip, but it is too late to change now. + +zip is an archiver: it compresses several files into a single archive +file. gzip is a simple compressor: each file is compressed separately. +Both share the same compression and decompression code for the +'deflate' method. unzip can also decompress old zip archives +(implode, shrink and reduce methods). gunzip can also decompress files +created by compress and pack. zip 1.9 and gzip do not support +compression methods other than deflation. (zip 1.0 supports shrink and +implode). Better compression methods may be added in future versions +of gzip. zip will always stick to absolute compatibility with pkzip, +it is thus constrained by PKWare, which is a commercial company. The +gzip header format is deliberately different from that of pkzip to +avoid such a constraint. + +On Unix, gzip is mostly useful in combination with tar. GNU tar +1.11.2 and later has a -z option to invoke gzip automatically. "tar -z" +compresses better than zip, since gzip can then take advantage of +redundancy between distinct files. The drawback is that you must +scan the whole tar.gz file in order to extract a single file near +the end; unzip can directly seek to the end of the zip file. There +is no overhead when you extract the whole archive anyway. +If a member of a .zip archive is damaged, other files can still +be recovered. If a .tar.gz file is damaged, files beyond the failure +point cannot be recovered. (Future versions of gzip will have +error recovery features.) + +gzip and gunzip are distributed as a single program. zip and unzip +are, for historical reasons, two separate programs, although the +authors of these two programs work closely together in the info-zip +team. zip and unzip are not associated with the GNU project. +See http://www.cdrom.com/pub/infozip/ for more about zip and unzip. + + +======================================================================== + +Copyright (C) 1999, 2001, 2002, 2006, 2007 Free Software Foundation, Inc. +Copyright (C) 1992, 1993 Jean-loup Gailly + +Permission is granted to copy, distribute and/or modify this document +under the terms of the GNU Free Documentation License, Version 1.2 or +any later version published by the Free Software Foundation; with no +Invariant Sections, with no Front-Cover Texts, and with no Back-Cover +Texts.

Algorithm + +The deflation algorithm used by zip and gzip is a variation of LZ77 +(Lempel-Ziv 1977, see reference below). It finds duplicated strings in +the input data. The second occurrence of a string is replaced by a +pointer to the previous string, in the form of a pair (distance, +length). Distances are limited to 32K bytes, and lengths are limited +to 258 bytes. When a string does not occur anywhere in the previous +32K bytes, it is emitted as a sequence of literal bytes. (In this +description, 'string' must be taken as an arbitrary sequence of bytes, +and is not restricted to printable characters.) + +Literals or match lengths are compressed with one Huffman tree, and +match distances are compressed with another tree. The trees are stored +in a compact form at the start of each block. The blocks can have any +size (except that the compressed data for one block must fit in +available memory). A block is terminated when zip determines that it +would be useful to start another block with fresh trees. (This is +somewhat similar to compress.) + +Duplicated strings are found using a hash table. All input strings of +length 3 are inserted in the hash table. A hash index is computed for +the next 3 bytes. If the hash chain for this index is not empty, all +strings in the chain are compared with the current input string, and +the longest match is selected. + +The hash chains are searched starting with the most recent strings, to +favor small distances and thus take advantage of the Huffman encoding. +The hash chains are singly linked. There are no deletions from the +hash chains, the algorithm simply discards matches that are too old. + +To avoid a worst-case situation, very long hash chains are arbitrarily +truncated at a certain length, determined by a runtime option (zip -1 +to -9). So zip does not always find the longest possible match but +generally finds a match which is long enough. + +zip also defers the selection of matches with a lazy evaluation +mechanism. After a match of length N has been found, zip searches for a +longer match at the next input byte. If a longer match is found, the +previous match is truncated to a length of one (thus producing a single +literal byte) and the longer match is emitted afterwards. Otherwise, +the original match is kept, and the next match search is attempted only +N steps later. + +The lazy match evaluation is also subject to a runtime parameter. If +the current match is long enough, zip reduces the search for a longer +match, thus speeding up the whole process. If compression ratio is more +important than speed, zip attempts a complete second search even if +the first match is already long enough. + +The lazy match evaluation is not performed for the fastest compression +modes (speed options -1 to -3). For these fast modes, new strings +are inserted in the hash table only when no match was found, or +when the match is not too long. This degrades the compression ratio +but saves time since there are both fewer insertions and fewer searches. + + +2. gzip file format + +The pkzip format imposes a lot of overhead in various headers, which +are useful for an archiver but not necessary when only one file is +compressed. gzip uses a much simpler structure. Numbers are in little +endian format, and bit 0 is the least significant bit. +A gzip file is a sequence of compressed members. Each member has the +following structure: + +2 bytes magic header 0x1f, 0x8b (\037 \213) +1 byte compression method (0..7 reserved, 8 = deflate) +1 byte flags + bit 0 set: file probably ascii text + bit 1 set: continuation of multi-part gzip file + bit 2 set: extra field present + bit 3 set: original file name present + bit 4 set: file comment present + bit 5 set: file is encrypted + bit 6,7: reserved +4 bytes file modification time in Unix format +1 byte extra flags (depend on compression method) +1 byte operating system on which compression took place + +2 bytes optional part number (second part=1) +2 bytes optional extra field length +? bytes optional extra field +? bytes optional original file name, zero terminated +? bytes optional file comment, zero terminated +12 bytes optional encryption header +? bytes compressed data +4 bytes crc32 +4 bytes uncompressed input size modulo 2^32 + +The format was designed to allow single pass compression without any +backwards seek, and without a priori knowledge of the uncompressed +input size or the available size on the output media. If input does +not come from a regular disk file, the file modification time is set +to the time at which compression started. + +The time stamp is useful mainly when one gzip file is transferred over +a network. In this case it would not help to keep ownership +attributes. In the local case, the ownership attributes are preserved +by gzip when compressing/decompressing the file. A time stamp of zero +is ignored. + +Bit 0 in the flags is only an optional indication, which can be set by +a small lookahead in the input data. In case of doubt, the flag is +cleared indicating binary data. For systems which have different +file formats for ascii text and binary data, the decompressor can +use the flag to choose the appropriate format. + +The extra field, if present, must consist of one or more subfields, +each with the following format: + + subfield id : 2 bytes + subfield size : 2 bytes (little-endian format) + subfield data + +The subfield id can consist of two letters with some mnemonic value. +Please send any such id to . Ids with a zero second +byte are reserved for future use. The following ids are defined: + + Ap (0x41, 0x70) : Apollo file type information + +The subfield size is the size of the subfield data and does not +include the id and the size itself. The field 'extra field length' is +the total size of the extra field, including subfield ids and sizes. + +It must be possible to detect the end of the compressed data with any +compression format, regardless of the actual size of the compressed +data. If the compressed data cannot fit in one file (in particular for +diskettes), each part starts with a header as described above, but +only the last part has the crc32 and uncompressed size. A decompressor +may prompt for additional data for multipart compressed files. It is +desirable but not mandatory that multiple parts be extractable +independently so that partial data can be recovered if one of the +parts is damaged. This is possible only if no compression state is +kept from one part to the other. The compression-type dependent flags +can indicate this. + +If the file being compressed is on a file system with case insensitive +names, the original name field must be forced to lower case. There is +no original file name if the data was compressed from standard input. + +Compression is always performed, even if the compressed file is +slightly larger than the original. The worst case expansion is +a few bytes for the gzip file header, plus 5 bytes every 32K block, +or an expansion ratio of 0.015% for large files. Note that the actual +number of used disk blocks almost never increases. + +The encryption is that of zip 1.9. For the encryption check, the +last byte of the decoded encryption header must be zero. The time +stamp of an encrypted file might be set to zero to avoid giving a clue +about the construction of the random header. + +Jean-loup Gailly +gzip@gnu.org + +References: + +[LZ77] Ziv J., Lempel A., "A Universal Algorithm for Sequential Data +Compression", IEEE Transactions on Information Theory", Vol. 23, No. 3, +pp. 337-343. + +APPNOTE.TXT documentation file in PKZIP 1.93a.

Insertions are performed at each input character, whereas + * string matches are performed only when the previous match ends. So it + * is preferable to spend more time in matches to allow very fast string + * insertions and avoid deletions. The matching algorithm for small + * strings is inspired from that of Rabin & Karp. A brute force approach + * is used to find longer strings when a small match has been found. + * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze + * (by Leonid Broukhis). + * A previous version of this file used a more sophisticated algorithm + * (by Fiala and Greene) which is guaranteed to run in linear amortized + * time, but has a larger average cost, uses more memory and is patented. + * However the F&G algorithm may be faster for some highly redundant + * files if the parameter max_chain_length (described below) is too large. + * + * ACKNOWLEDGEMENTS + * + * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and + * I found it in 'freeze' written by Leonid Broukhis. + * Thanks to many info-zippers for bug reports and testing. + * + * REFERENCES + * + * APPNOTE.TXT documentation file in PKZIP 1.93a distribution. + * + * A description of the Rabin and Karp algorithm is given in the book + * "Algorithms" by R.

It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + +@item +APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The ``Document'', below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as ``you''. You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A ``Modified Version'' of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A ``Secondary Section'' is a named appendix or a front-matter section +of the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall +subject (or to related matters) and contains nothing that could fall +directly within that overall subject. (Thus, if the Document is in +part a textbook of mathematics, a Secondary Section may not explain +any mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The ``Invariant Sections'' are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The ``Cover Texts'' are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A ``Transparent'' copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not ``Transparent'' is called ``Opaque''. + +Examples of suitable formats for Transparent copies include plain +@sc{ascii} without markup, Texinfo input format, La@TeX{} input +format, @acronym{SGML} or @acronym{XML} using a publicly available +@acronym{DTD}, and standard-conforming simple @acronym{HTML}, +PostScript or @acronym{PDF} designed for human modification. Examples +of transparent image formats include @acronym{PNG}, @acronym{XCF} and +@acronym{JPG}. Opaque formats include proprietary formats that can be +read and edited only by proprietary word processors, @acronym{SGML} or +@acronym{XML} for which the @acronym{DTD} and/or processing tools are +not generally available, and the machine-generated @acronym{HTML}, +PostScript or @acronym{PDF} produced by some word processors for +output purposes only. + +The ``Title Page'' means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, ``Title Page'' means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +A section ``Entitled XYZ'' means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as ``Acknowledgements'', +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' +of such a section when you modify the Document means that it remains a +section ``Entitled XYZ'' according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the ``History'' section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles. Section numbers +or the equivalent are not considered part of the section titles. + +@item +Delete any section Entitled ``Endorsements''. Such a section +may not be included in the Modified Version. + +@item +Do not retitle any existing section to be Entitled ``Endorsements'' or +to conflict in title with any Invariant Section. + +@item +Preserve any Warranty Disclaimers. +@end enumerate + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled ``Endorsements'', provided it contains +nothing but endorsements of your Modified Version by various +parties---for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled ``History'' +in the various original documents, forming one section Entitled +``History''; likewise combine any sections Entitled ``Acknowledgements'', +and any sections Entitled ``Dedications''. You must delete all +sections Entitled ``Endorsements.'' + +@item +COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + +@item +AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an ``aggregate'' if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + +@item +TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled ``Acknowledgements'', +``Dedications'', or ``History'', the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + +@item +TERMINATION + +You may not copy, modify, sublicense, or distribute the Document except +as expressly provided for under this License. Any other attempt to +copy, modify, sublicense or distribute the Document is void, and will +automatically terminate your rights under this License. However, +parties who have received copies, or rights, from you under this +License will not have their licenses terminated so long as such +parties remain in full compliance. + +@item +FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +@uref{http://www.gnu.org/copyleft/}. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. +@end enumerate + +@page +@heading ADDENDUM: How to use this License for your documents + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: + +@smallexample +@group + Copyright (C) @var{year} @var{your name}. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.2 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts.

Whenever possible, each file is replaced by one with the +extension `.gz', while keeping the same ownership modes, access and +modification times. (The default extension is `-gz' for VMS, `z' for +MSDOS, OS/2 FAT and Atari.) If no files are specified or if a file +name is "-", the standard input is compressed to the standard output. +`gzip' will only attempt to compress regular files. In particular, it +will ignore symbolic links. + + If the new file name is too long for its file system, `gzip' +truncates it. `gzip' attempts to truncate only the parts of the file +name longer than 3 characters. (A part is delimited by dots.) If the +name consists of small parts only, the longest parts are truncated. +For example, if file names are limited to 14 characters, gzip.msdos.exe +is compressed to gzi.msd.exe.gz. Names are not truncated on systems +which do not have a limit on file name length. + + By default, `gzip' keeps the original file name and time stamp in +the compressed file. These are used when decompressing the file with +the `-N' option. This is useful when the compressed file name was +truncated or when the time stamp was not preserved after a file +transfer. However, due to limitations in the current `gzip' file +format, fractional seconds are discarded. Also, time stamps must fall +within the range 1970-01-01 00:00:00 through 2106-02-07 06:28:15 UTC, +and hosts whose operating systems use 32-bit time stamps are further +restricted to time stamps no later than 2038-01-19 03:14:07 UTC. The +upper bounds assume the typical case where leap seconds are ignored. + + Compressed files can be restored to their original form using `gzip +-d' or `gunzip' or `zcat'. If the original name saved in the +compressed file is not suitable for its file system, a new name is +constructed from the original one to make it legal. + + `gunzip' takes a list of files on its command line and replaces each +file whose name ends with `.gz', `.z', `.Z', `-gz', `-z' or `_z' and +which begins with the correct magic number with an uncompressed file +without the original extension. `gunzip' also recognizes the special +extensions `.tgz' and `.taz' as shorthands for `.tar.gz' and `.tar.Z' +respectively. When compressing, `gzip' uses the `.tgz' extension if +necessary instead of truncating a file with a `.tar' extension. + + `gunzip' can currently decompress files created by `gzip', `zip', +`compress' or `pack'. The detection of the input format is automatic. +When using the first two formats, `gunzip' checks a 32 bit CRC (cyclic +redundancy check). For `pack', `gunzip' checks the uncompressed +length. The `compress' format was not designed to allow consistency +checks. However `gunzip' is sometimes able to detect a bad `.Z' file. +If you get an error when uncompressing a `.Z' file, do not assume that +the `.Z' file is correct simply because the standard `uncompress' does +not complain. This generally means that the standard `uncompress' does +not check its input, and happily generates garbage output. The SCO +`compress -H' format (LZH compression method) does not include a CRC but +also allows some consistency checks. + + Files created by `zip' can be uncompressed by `gzip' only if they +have a single member compressed with the 'deflation' method. This +feature is only intended to help conversion of `tar.zip' files to the +`tar.gz' format. To extract a `zip' file with a single member, use a +command like `gunzip . + + This is the output of the command `gzip -v texinfo.tex': + + texinfo.tex: 69.3% -- replaced with texinfo.tex.gz + + The following command will find all regular `.gz' files in the +current directory and subdirectories (skipping file names that contain +newlines), and extract them in place without destroying the original, +stopping on the first failure: + + find . -name '* + *' -prune -o -name '*.gz' -type f -print | + sed " + s/'/'\\''/g + s/^\\(.*\\)\\.gz$/gunzip <'\\1.gz' >'\\1'/ + " | + sh -e + + +File: gzip.info, Node: Invoking gzip, Next: Advanced usage, Prev: Sample, Up: Top + +3 Invoking `gzip' +***************** + +The format for running the `gzip' program is: + + gzip OPTION ... + + `gzip' supports the following options: + +`--stdout' +`--to-stdout' +`-c' + Write output on standard output; keep original files unchanged. + If there are several input files, the output consists of a + sequence of independently compressed members.

In this case, `gunzip' +will extract all members at once. If one member is damaged, other +members might still be recovered after removal of the damaged member. +Better compression can be usually obtained if all members are +decompressed and then recompressed in a single step. + + This is an example of concatenating `gzip' files: + + gzip -c file1 > foo.gz + gzip -c file2 >> foo.gz + +Then + + gunzip -c foo + +is equivalent to + + cat file1 file2 + + In case of damage to one member of a `.gz' file, other members can +still be recovered (if the damaged member is removed).

If you need the uncompressed size for all members, you can use: + + zcat file.gz | wc -c + + If you wish to create a single archive file with multiple members so +that members can later be extracted independently, use an archiver such +as `tar' or `zip'. GNU `tar' supports the `-z' option to invoke `gzip' +transparently. `gzip' is designed as a complement to `tar', not as a +replacement. + + +File: gzip.info, Node: Environment, Next: Tapes, Prev: Advanced usage, Up: Top + +5 Environment +************* + +The environment variable `GZIP' can hold a set of default options for +`gzip'. These options are interpreted first and can be overwritten by +explicit command line parameters. For example: + + for sh: GZIP="-8v --name"; export GZIP + for csh: setenv GZIP "-8v --name" + for MSDOS: set GZIP=-8v --name + + On VMS, the name of the environment variable is `GZIP_OPT', to avoid +a conflict with the symbol set for invocation of the program. + + +File: gzip.info, Node: Tapes, Next: Problems, Prev: Environment, Up: Top + +6 Using `gzip' on tapes +*********************** + +When writing compressed data to a tape, it is generally necessary to pad +the output with zeroes up to a block boundary. When the data is read +and the whole block is passed to `gunzip' for decompression, `gunzip' +detects that there is extra trailing garbage after the compressed data +and emits a warning by default if the garbage contains nonzero bytes. +You have to use the `--quiet' option to suppress the warning. This +option can be set in the `GZIP' environment variable, as in: + + for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0 + for csh: (setenv GZIP "-q"; tar -xfz --block-compress /dev/rst0) + + In the above example, `gzip' is invoked implicitly by the `-z' +option of GNU `tar'. Make sure that the same block size (`-b' option +of `tar') is used for reading and writing compressed data on tapes. +(This example assumes you are using the GNU version of `tar'.) + + +File: gzip.info, Node: Problems, Next: Copying This Manual, Prev: Tapes, Up: Top + +7 Reporting Bugs +**************** + +If you find a bug in `gzip', please send electronic mail to +.

PREAMBLE + + The purpose of this License is to make a manual, textbook, or other + functional and useful document "free" in the sense of freedom: to + assure everyone the effective freedom to copy and redistribute it, + with or without modifying it, either commercially or + noncommercially. Secondarily, this License preserves for the + author and publisher a way to get credit for their work, while not + being considered responsible for modifications made by others. + + This License is a kind of "copyleft", which means that derivative + works of the document must themselves be free in the same sense. + It complements the GNU General Public License, which is a copyleft + license designed for free software. + + We have designed this License in order to use it for manuals for + free software, because free software needs free documentation: a + free program should come with manuals providing the same freedoms + that the software does. But this License is not limited to + software manuals; it can be used for any textual work, regardless + of subject matter or whether it is published as a printed book. + We recommend this License principally for works whose purpose is + instruction or reference. + + 1. APPLICABILITY AND DEFINITIONS + + This License applies to any manual or other work, in any medium, + that contains a notice placed by the copyright holder saying it + can be distributed under the terms of this License. Such a notice + grants a world-wide, royalty-free license, unlimited in duration, + to use that work under the conditions stated herein. The + "Document", below, refers to any such manual or work. Any member + of the public is a licensee, and is addressed as "you". You + accept the license if you copy, modify or distribute the work in a + way requiring permission under copyright law. + + A "Modified Version" of the Document means any work containing the + Document or a portion of it, either copied verbatim, or with + modifications and/or translated into another language. + + A "Secondary Section" is a named appendix or a front-matter section + of the Document that deals exclusively with the relationship of the + publishers or authors of the Document to the Document's overall + subject (or to related matters) and contains nothing that could + fall directly within that overall subject. (Thus, if the Document + is in part a textbook of mathematics, a Secondary Section may not + explain any mathematics.) The relationship could be a matter of + historical connection with the subject or with related matters, or + of legal, commercial, philosophical, ethical or political position + regarding them. + + The "Invariant Sections" are certain Secondary Sections whose + titles are designated, as being those of Invariant Sections, in + the notice that says that the Document is released under this + License. If a section does not fit the above definition of + Secondary then it is not allowed to be designated as Invariant. + The Document may contain zero Invariant Sections. If the Document + does not identify any Invariant Sections then there are none. + + The "Cover Texts" are certain short passages of text that are + listed, as Front-Cover Texts or Back-Cover Texts, in the notice + that says that the Document is released under this License. A + Front-Cover Text may be at most 5 words, and a Back-Cover Text may + be at most 25 words. + + A "Transparent" copy of the Document means a machine-readable copy, + represented in a format whose specification is available to the + general public, that is suitable for revising the document + straightforwardly with generic text editors or (for images + composed of pixels) generic paint programs or (for drawings) some + widely available drawing editor, and that is suitable for input to + text formatters or for automatic translation to a variety of + formats suitable for input to text formatters. A copy made in an + otherwise Transparent file format whose markup, or absence of + markup, has been arranged to thwart or discourage subsequent + modification by readers is not Transparent. An image format is + not Transparent if used for any substantial amount of text. A + copy that is not "Transparent" is called "Opaque". + + Examples of suitable formats for Transparent copies include plain + ASCII without markup, Texinfo input format, LaTeX input format, + SGML or XML using a publicly available DTD, and + standard-conforming simple HTML, PostScript or PDF designed for + human modification. Examples of transparent image formats include + PNG, XCF and JPG. Opaque formats include proprietary formats that + can be read and edited only by proprietary word processors, SGML or + XML for which the DTD and/or processing tools are not generally + available, and the machine-generated HTML, PostScript or PDF + produced by some word processors for output purposes only. + + The "Title Page" means, for a printed book, the title page itself, + plus such following pages as are needed to hold, legibly, the + material this License requires to appear in the title page. For + works in formats which do not have any title page as such, "Title + Page" means the text near the most prominent appearance of the + work's title, preceding the beginning of the body of the text. + + A section "Entitled XYZ" means a named subunit of the Document + whose title either is precisely XYZ or contains XYZ in parentheses + following text that translates XYZ in another language. (Here XYZ + stands for a specific section name mentioned below, such as + "Acknowledgements", "Dedications", "Endorsements", or "History".) + To "Preserve the Title" of such a section when you modify the + Document means that it remains a section "Entitled XYZ" according + to this definition. + + The Document may include Warranty Disclaimers next to the notice + which states that this License applies to the Document. These + Warranty Disclaimers are considered to be included by reference in + this License, but only as regards disclaiming warranties: any other + implication that these Warranty Disclaimers may have is void and + has no effect on the meaning of this License. + + 2. VERBATIM COPYING + + You may copy and distribute the Document in any medium, either + commercially or noncommercially, provided that this License, the + copyright notices, and the license notice saying this License + applies to the Document are reproduced in all copies, and that you + add no other conditions whatsoever to those of this License. You + may not use technical measures to obstruct or control the reading + or further copying of the copies you make or distribute. However, + you may accept compensation in exchange for copies. If you + distribute a large enough number of copies you must also follow + the conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + + 3. COPYING IN QUANTITY + + If you publish printed copies (or copies in media that commonly + have printed covers) of the Document, numbering more than 100, and + the Document's license notice requires Cover Texts, you must + enclose the copies in covers that carry, clearly and legibly, all + these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the + title equally prominent and visible. You may add other material + on the covers in addition. Copying with changes limited to the + covers, as long as they preserve the title of the Document and + satisfy these conditions, can be treated as verbatim copying in + other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a + machine-readable Transparent copy along with each Opaque copy, or + state in or with each Opaque copy a computer-network location from + which the general network-using public has access to download + using public-standard network protocols a complete Transparent + copy of the Document, free of added material. If you use the + latter option, you must take reasonably prudent steps, when you + begin distribution of Opaque copies in quantity, to ensure that + this Transparent copy will remain thus accessible at the stated + location until at least one year after the last time you + distribute an Opaque copy (directly or through your agents or + retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of + copies, to give them a chance to provide you with an updated + version of the Document. + + 4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with + the Modified Version filling the role of the Document, thus + licensing distribution and modification of the Modified Version to + whoever possesses a copy of it. In addition, you must do these + things in the Modified Version: + + A. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of + previous versions (which should, if there were any, be listed + in the History section of the Document). You may use the + same title as a previous version if the original publisher of + that version gives permission. + + B. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in + the Modified Version, together with at least five of the + principal authors of the Document (all of its principal + authors, if it has fewer than five), unless they release you + from this requirement. + + C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + D. Preserve all the copyright notices of the Document. + + E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + F. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified + Version under the terms of this License, in the form shown in + the Addendum below. + + G. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's + license notice. + + H. Include an unaltered copy of this License. + + I. Preserve the section Entitled "History", Preserve its Title, + and add to it an item stating at least the title, year, new + authors, and publisher of the Modified Version as given on + the Title Page. If there is no section Entitled "History" in + the Document, create one stating the title, year, authors, + and publisher of the Document as given on its Title Page, + then add an item describing the Modified Version as stated in + the previous sentence. + + J. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in + the "History" section. You may omit a network location for a + work that was published at least four years before the + Document itself, or if the original publisher of the version + it refers to gives permission. + + K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the + section all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + + L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section + titles. + + M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. + + N. Do not retitle any existing section to be Entitled + "Endorsements" or to conflict in title with any Invariant + Section. + + O. Preserve any Warranty Disclaimers. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no + material copied from the Document, you may at your option + designate some or all of these sections as invariant. To do this, + add their titles to the list of Invariant Sections in the Modified + Version's license notice. These titles must be distinct from any + other section titles. + + You may add a section Entitled "Endorsements", provided it contains + nothing but endorsements of your Modified Version by various + parties--for example, statements of peer review or that the text + has been approved by an organization as the authoritative + definition of a standard. + + You may add a passage of up to five words as a Front-Cover Text, + and a passage of up to 25 words as a Back-Cover Text, to the end + of the list of Cover Texts in the Modified Version. Only one + passage of Front-Cover Text and one of Back-Cover Text may be + added by (or through arrangements made by) any one entity. If the + Document already includes a cover text for the same cover, + previously added by you or by arrangement made by the same entity + you are acting on behalf of, you may not add another; but you may + replace the old one, on explicit permission from the previous + publisher that added the old one. + + The author(s) and publisher(s) of the Document do not by this + License give permission to use their names for publicity for or to + assert or imply endorsement of any Modified Version. + + 5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination + all of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice, and that you preserve all + their Warranty Disclaimers. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else a + unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections Entitled + "History" in the various original documents, forming one section + Entitled "History"; likewise combine any sections Entitled + "Acknowledgements", and any sections Entitled "Dedications". You + must delete all sections Entitled "Endorsements." + + 6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the + documents in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow + this License in all other respects regarding verbatim copying of + that document. + + 7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of + a storage or distribution medium, is called an "aggregate" if the + copyright resulting from the compilation is not used to limit the + legal rights of the compilation's users beyond what the individual + works permit. When the Document is included in an aggregate, this + License does not apply to the other works in the aggregate which + are not themselves derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one half + of the entire aggregate, the Document's Cover Texts may be placed + on covers that bracket the Document within the aggregate, or the + electronic equivalent of covers if the Document is in electronic + form. Otherwise they must appear on printed covers that bracket + the whole aggregate. + + 8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of section + 4. Replacing Invariant Sections with translations requires special + permission from their copyright holders, but you may include + translations of some or all Invariant Sections in addition to the + original versions of these Invariant Sections. You may include a + translation of this License, and all the license notices in the + Document, and any Warranty Disclaimers, provided that you also + include the original English version of this License and the + original versions of those notices and disclaimers. In case of a + disagreement between the translation and the original version of + this License or a notice or disclaimer, the original version will + prevail. + + If a section in the Document is Entitled "Acknowledgements", + "Dedications", or "History", the requirement (section 4) to + Preserve its Title (section 1) will typically require changing the + actual title. + + 9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided for under this License. Any other + attempt to copy, modify, sublicense or distribute the Document is + void, and will automatically terminate your rights under this + License. However, parties who have received copies, or rights, + from you under this License will not have their licenses + terminated so long as such parties remain in full compliance. + + 10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + `http://www.gnu.org/copyleft/'. + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If + the Document does not specify a version number of this License, + you may choose any version ever published (not as a draft) by the + Free Software Foundation. + +ADDENDUM: How to use this License for your documents +==================================================== + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.2 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts. A copy of the license is included in the section entitled ``GNU + Free Documentation License''. + + If you have Invariant Sections, Front-Cover Texts and Back-Cover +Texts, replace the "with...Texts." line with this: + + with the Invariant Sections being LIST THEIR TITLES, with + the Front-Cover Texts being LIST, and with the Back-Cover Texts + being LIST. + + If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + + If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of +free software license, such as the GNU General Public License, to +permit their use in free software. + + +File: gzip.info, Node: Concept Index, Prev: Copying This Manual, Up: Top + +Appendix B Concept Index +************************ + +[index] +* Menu: + +* bugs: Problems.

Whenever possible, each file is replaced by one with the +extension @samp{.gz}, while keeping the same ownership modes, access and +modification times. (The default extension is @option{-gz} for @abbr{VMS}, +@samp{z} for @abbr{MSDOS}, @abbr{OS/2} @abbr{FAT} and Atari.) +If no files are specified or +if a file name is "-", the standard input is compressed to the standard +output. @command{gzip} will only attempt to compress regular files. In +particular, it will ignore symbolic links. + +If the new file name is too long for its file system, @command{gzip} +truncates it. @command{gzip} attempts to truncate only the parts of the +file name longer than 3 characters. (A part is delimited by dots.) If +the name consists of small parts only, the longest parts are truncated. +For example, if file names are limited to 14 characters, gzip.msdos.exe +is compressed to gzi.msd.exe.gz. Names are not truncated on systems +which do not have a limit on file name length. + +By default, @command{gzip} keeps the original file name and time stamp in +the compressed file. These are used when decompressing the file with the +@option{-N} option. This is useful when the compressed file name was +truncated or when the time stamp was not preserved after a file +transfer. However, due to limitations in the current @command{gzip} file +format, fractional seconds are discarded. Also, time stamps must fall +within the range 1970-01-01 00:00:00 through 2106-02-07 06:28:15 +@abbr{UTC}, and hosts whose operating systems use 32-bit time +stamps are further restricted to time stamps no later than 2038-01-19 +03:14:07 @abbr{UTC}. The upper bounds assume the typical case +where leap seconds are ignored. + +Compressed files can be restored to their original form using @samp{gzip -d} +or @command{gunzip} or @command{zcat}. If the original name saved in the +compressed file is not suitable for its file system, a new name is +constructed from the original one to make it legal. + +@command{gunzip} takes a list of files on its command line and replaces +each file whose name ends with @samp{.gz}, @samp{.z}, @samp{.Z}, +@option{-gz}, @option{-z} or @samp{_z} and which begins with the correct +magic number with an uncompressed file without the original extension. +@command{gunzip} also recognizes the special extensions @samp{.tgz} and +@samp{.taz} as shorthands for @samp{.tar.gz} and @samp{.tar.Z} +respectively. When compressing, @command{gzip} uses the @samp{.tgz} +extension if necessary instead of truncating a file with a @samp{.tar} +extension. + +@command{gunzip} can currently decompress files created by @command{gzip}, +@command{zip}, @command{compress} or @command{pack}. The detection of the input +format is automatic. When using the first two formats, @command{gunzip} +checks a 32 bit @abbr{CRC} (cyclic redundancy check). For @command{pack}, +@command{gunzip} checks the uncompressed length. The @command{compress} format +was not designed to allow consistency checks. However @command{gunzip} is +sometimes able to detect a bad @samp{.Z} file. If you get an error when +uncompressing a @samp{.Z} file, do not assume that the @samp{.Z} file is +correct simply because the standard @command{uncompress} does not complain. +This generally means that the standard @command{uncompress} does not check +its input, and happily generates garbage output. The @abbr{SCO} @samp{compress +-H} format (@abbr{LZH} compression method) does not include a @abbr{CRC} but +also allows some consistency checks. + +Files created by @command{zip} can be uncompressed by @command{gzip} only if +they have a single member compressed with the 'deflation' method. This +feature is only intended to help conversion of @file{tar.zip} files to +the @file{tar.gz} format. To extract a @command{zip} file with a single +member, use a command like @samp{gunzip . +@end example + +This is the output of the command @samp{gzip -v texinfo.tex}: + +@example +texinfo.tex: 69.3% -- replaced with texinfo.tex.gz +@end example + +The following command will find all regular @samp{.gz} files in the +current directory and subdirectories (skipping file names that contain +newlines), and extract them in place without destroying the original, +stopping on the first failure: + +@example +find . -name '* +*' -prune -o -name '*.gz' -type f -print | + sed " + s/'/'\\''/g + s/^\\(.*\\)\\.gz$/gunzip <'\\1.gz' >'\\1'/ + " | + sh -e +@end example + +@node Invoking gzip +@chapter Invoking @command{gzip} +@cindex invoking +@cindex options + +The format for running the @command{gzip} program is: + +@example +gzip @var{option} @dots{} +@end example + +@command{gzip} supports the following options: + +@table @option +@item --stdout +@itemx --to-stdout +@itemx -c +Write output on standard output; keep original files unchanged. +If there are several input files, the output consists of a sequence of +independently compressed members. To obtain better compression, +concatenate all input files before compressing them. + +@item --decompress +@itemx --uncompress +@itemx -d +Decompress. + +@item --force +@itemx -f +Force compression or decompression even if the file has multiple links +or the corresponding file already exists, or if the compressed data +is read from or written to a terminal. If the input data is not in +a format recognized by @command{gzip}, and if the option @option{--stdout} is also +given, copy the input data without change to the standard output: let +@command{zcat} behave as @command{cat}. If @option{-f} is not given, and +when not running in the background, @command{gzip} prompts to verify +whether an existing file should be overwritten. + +@item --help +@itemx -h +Print an informative help message describing the options then quit. + +@item --list +@itemx -l +For each compressed file, list the following fields: + +@example +compressed size: size of the compressed file +uncompressed size: size of the uncompressed file +ratio: compression ratio (0.0% if unknown) +uncompressed_name: name of the uncompressed file +@end example + +The uncompressed size is given as @minus{}1 for files not in @command{gzip} +format, such as compressed @samp{.Z} files. To get the uncompressed size for +such a file, you can use: + +@example +zcat file.Z | wc -c +@end example + +In combination with the @option{--verbose} option, the following fields are also +displayed: + +@example +method: compression method (deflate,compress,lzh,pack) +crc: the 32-bit CRC of the uncompressed data +date & time: time stamp for the uncompressed file +@end example + +The @abbr{CRC} is given as ffffffff for a file not in gzip format. + +With @option{--verbose}, the size totals and compression ratio for all files +is also displayed, unless some sizes are unknown. With @option{--quiet}, +the title and totals lines are not displayed. + +The @command{gzip} format represents the input size modulo +@math{2^32}, so the uncompressed size and compression ratio are listed +incorrectly for uncompressed files 4 GiB and larger. To work around +this problem, you can use the following command to discover a large +uncompressed file's true size: + +@example +zcat file.gz | wc -c +@end example + +@item --license +@itemx -L +Display the @command{gzip} license then quit. + +@item --no-name +@itemx -n +When compressing, do not save the original file name and time stamp by +default. (The original name is always saved if the name had to be +truncated.) When decompressing, do not restore the original file name +if present (remove only the @command{gzip} +suffix from the compressed file name) and do not restore the original +time stamp if present (copy it from the compressed file). This option +is the default when decompressing. + +@item --name +@itemx -N +When compressing, always save the original file name and time stamp; this +is the default.

The default +compression level is @option{-6} (that is, biased towards high compression at +expense of speed). +@end table + +@node Advanced usage +@chapter Advanced usage +@cindex concatenated files + +Multiple compressed files can be concatenated. In this case, +@command{gunzip} will extract all members at once. If one member is +damaged, other members might still be recovered after removal of the +damaged member. Better compression can be usually obtained if all +members are decompressed and then recompressed in a single step. + +This is an example of concatenating @command{gzip} files: + +@example +gzip -c file1 > foo.gz +gzip -c file2 >> foo.gz +@end example + +@noindent +Then + +@example +gunzip -c foo +@end example + +@noindent +is equivalent to + +@example +cat file1 file2 +@end example + +In case of damage to one member of a @samp{.gz} file, other members can +still be recovered (if the damaged member is removed). However, +you can get better compression by compressing all members at once: + +@example +cat file1 file2 | gzip > foo.gz +@end example + +@noindent +compresses better than + +@example +gzip -c file1 file2 > foo.gz +@end example + +If you want to recompress concatenated files to get better compression, do: + +@example +zcat old.gz | gzip > new.gz +@end example + +If a compressed file consists of several members, the uncompressed +size and @abbr{CRC} reported by the @option{--list} option applies to +the last member +only. If you need the uncompressed size for all members, you can use: + +@example +zcat file.gz | wc -c +@end example + +If you wish to create a single archive file with multiple members so +that members can later be extracted independently, use an archiver such +as @command{tar} or @command{zip}. @acronym{GNU} @command{tar} +supports the @option{-z} +option to invoke @command{gzip} transparently. @command{gzip} is designed as a +complement to @command{tar}, not as a replacement. + +@node Environment +@chapter Environment +@cindex Environment + +The environment variable @env{GZIP} can hold a set of default options for +@command{gzip}. These options are interpreted first and can be overwritten by +explicit command line parameters. For example: + +@example +for sh: GZIP="-8v --name"; export GZIP +for csh: setenv GZIP "-8v --name" +for MSDOS: set GZIP=-8v --name +@end example + +On @abbr{VMS}, the name of the environment variable is @env{GZIP_OPT}, to +avoid a conflict with the symbol set for invocation of the program. + +@node Tapes +@chapter Using @command{gzip} on tapes +@cindex tapes + +When writing compressed data to a tape, it is generally necessary to pad +the output with zeroes up to a block boundary. When the data is read and +the whole block is passed to @command{gunzip} for decompression, +@command{gunzip} detects that there is extra trailing garbage after the +compressed data and emits a warning by default if the garbage contains +nonzero bytes. You have to use the +@option{--quiet} option to suppress the warning. This option can be set in the +@env{GZIP} environment variable, as in: + +@example +for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0 +for csh: (setenv GZIP "-q"; tar -xfz --block-compress /dev/rst0) +@end example + +In the above example, @command{gzip} is invoked implicitly by the @option{-z} +option of @acronym{GNU} @command{tar}. Make sure that the same block +size (@option{-b} +option of @command{tar}) is used for reading and writing compressed data on +tapes. (This example assumes you are using the @acronym{GNU} version of +@command{tar}.) + +@node Problems +@chapter Reporting Bugs +@cindex bugs + +If you find a bug in @command{gzip}, please send electronic mail to +@email{bug-gzip@@gnu.org}.

This is useful when the compressed file name was truncated or +when the time stamp was not preserved after a file transfer. +.PP +Compressed files can be restored to their original form using +.I gzip -d +or +.I gunzip +or +.I zcat. +If the original name saved in the compressed file is not suitable for its +file system, a new name is constructed from the original one to make it +legal. +.PP +.I gunzip +takes a list of files on its command line and replaces each +file whose name ends with .gz, -gz, .z, -z, _z or .Z +and which begins with the correct magic number with an uncompressed +file without the original extension. +.I gunzip +also recognizes the special extensions +.B "\&.tgz" +and +.B "\&.taz" +as shorthands for +.B "\&.tar.gz" +and +.B "\&.tar.Z" +respectively. +When compressing, +.I gzip +uses the +.B "\&.tgz" +extension if necessary instead of truncating a file with a +.B "\&.tar" +extension. +.PP +.I gunzip +can currently decompress files created by +.I gzip, zip, compress, compress -H +or +.I pack. +The detection of the input format is automatic. When using +the first two formats, +.I gunzip +checks a 32 bit CRC. For +.I pack, gunzip +checks the uncompressed length. The standard +.I compress +format was not designed to allow consistency checks. However +.I gunzip +is sometimes able to detect a bad .Z file. If you get an error +when uncompressing a .Z file, do not assume that the .Z file is +correct simply because the standard +.I uncompress +does not complain. This generally means that the standard +.I uncompress +does not check its input, and happily generates garbage output. +The SCO compress -H format (lzh compression method) does not include a CRC +but also allows some consistency checks. +.PP +Files created by +.I zip +can be uncompressed by gzip only if they have a single member compressed +with the 'deflation' method. This feature is only intended to help +conversion of tar.zip files to the tar.gz format. To extract a +.I zip +file with a single member, use a command like +.I "gunzip , +Internet RFC 1952 (May 1996). The +.I zip +deflation format is specified in P. Deutsch, \s-1DEFLATE\s0 Compressed +Data Format Specification version 1.3, +, Internet RFC 1951 (May 1996). + +.SH OPTIONS +.TP +.B \-a --ascii +Ascii text mode: convert end-of-lines using local conventions. This option +is supported only on some non-Unix systems. For MSDOS, CR LF is converted +to LF when compressing, and LF is converted to CR LF when decompressing. +.TP +.B \-c --stdout --to-stdout +Write output on standard output; keep original files unchanged. +If there are several input files, the output consists of a sequence of +independently compressed members. To obtain better compression, +concatenate all input files before compressing them. +.TP +.B \-d --decompress --uncompress +Decompress. +.TP +.B \-f --force +Force compression or decompression even if the file has multiple links +or the corresponding file already exists, or if the compressed data +is read from or written to a terminal. If the input data is not in +a format recognized by +.I gzip, +and if the option --stdout is also given, copy the input data without change +to the standard output: let +.I zcat +behave as +.I cat. +If +.B \-f +is not given, +and when not running in the background, +.I gzip +prompts to verify whether an existing file should be overwritten. +.TP +.B \-h --help +Display a help screen and quit. +.TP +.B \-l --list +For each compressed file, list the following fields: + + compressed size: size of the compressed file + uncompressed size: size of the uncompressed file + ratio: compression ratio (0.0% if unknown) + uncompressed_name: name of the uncompressed file + +The uncompressed size is given as -1 for files not in gzip format, +such as compressed .Z files. To get the uncompressed size for such a file, +you can use: + + zcat file.Z | wc -c + +In combination with the --verbose option, the following fields are also +displayed: + + method: compression method + crc: the 32-bit CRC of the uncompressed data + date & time: time stamp for the uncompressed file + +The compression methods currently supported are deflate, compress, lzh +(SCO compress -H) and pack. The crc is given as ffffffff for a file +not in gzip format. + +With --name, the uncompressed name, date and time are +those stored within the compress file if present. + +With --verbose, the size totals and compression ratio for all files +is also displayed, unless some sizes are unknown. With --quiet, +the title and totals lines are not displayed. +.TP +.B \-L --license +Display the +.I gzip +license and quit. +.TP +.B \-n --no-name +When compressing, do not save the original file name and time stamp by +default. (The original name is always saved if the name had to be +truncated.) When decompressing, do not restore the original file name +if present (remove only the +.I gzip +suffix from the compressed file name) and do not restore the original +time stamp if present (copy it from the compressed file). This option +is the default when decompressing. +.TP +.B \-N --name +When compressing, always save the original file name and time stamp; this +is the default. When decompressing, restore the original file name and +time stamp if present. This option is useful on systems which have +a limit on file name length or when the time stamp has been lost after +a file transfer. +.TP +.B \-q --quiet +Suppress all warnings. +.TP +.B \-r --recursive +Travel the directory structure recursively. If any of the file names +specified on the command line are directories, +.I gzip +will descend into the directory and compress all the files it finds there +(or decompress them in the case of +.I gunzip +). +.TP +.B \-S .suf --suffix .suf +Use suffix .suf instead of .gz. Any suffix can be given, but suffixes +other than .z and .gz should be avoided to avoid confusion when files +are transferred to other systems. A null suffix forces gunzip to try +decompression on all given files regardless of suffix, as in: + + gunzip -S "" * (*.* for MSDOS) + +Previous versions of gzip used +the .z suffix. This was changed to avoid a conflict with +.IR pack "(1)". +.TP +.B \-t --test +Test. Check the compressed file integrity. +.TP +.B \-v --verbose +Verbose. Display the name and percentage reduction for each file compressed +or decompressed. +.TP +.B \-V --version +Version. Display the version number and compilation options then quit. +.TP +.B \-# --fast --best +Regulate the speed of compression using the specified digit +.IR # , +where +.B \-1 +or +.B \-\-fast +indicates the fastest compression method (less compression) +and +.B \-9 +or +.B \-\-best +indicates the slowest compression method (best compression). +The default compression level is +.BR \-6 +(that is, biased towards high compression at expense of speed). +.SH "ADVANCED USAGE" +Multiple compressed files can be concatenated. In this case, +.I gunzip +will extract all members at once. For example: + + gzip -c file1 > foo.gz + gzip -c file2 >> foo.gz + +Then + + gunzip -c foo + +is equivalent to + + cat file1 file2 + +In case of damage to one member of a .gz file, other members can +still be recovered (if the damaged member is removed). However, +you can get better compression by compressing all members at once: + + cat file1 file2 | gzip > foo.gz + +compresses better than + + gzip -c file1 file2 > foo.gz + +If you want to recompress concatenated files to get better compression, do: + + gzip -cd old.gz | gzip > new.gz + +If a compressed file consists of several members, the uncompressed +size and CRC reported by the --list option applies to the last member +only. If you need the uncompressed size for all members, you can use: + + gzip -cd file.gz | wc -c + +If you wish to create a single archive file with multiple members so +that members can later be extracted independently, use an archiver +such as tar or zip. GNU tar supports the -z option to invoke gzip +transparently. gzip is designed as a complement to tar, not as a +replacement. +.SH "ENVIRONMENT" +The environment variable +.B GZIP +can hold a set of default options for +.I gzip. +These options are interpreted first and can be overwritten by +explicit command line parameters. For example: + for sh: GZIP="-8v --name"; export GZIP + for csh: setenv GZIP "-8v --name" + for MSDOS: set GZIP=-8v --name + +On Vax/VMS, the name of the environment variable is GZIP_OPT, to +avoid a conflict with the symbol set for invocation of the program. +.SH "SEE ALSO" +znew(1), zcmp(1), zmore(1), zforce(1), gzexe(1), zip(1), unzip(1), compress(1), +pack(1), compact(1) +.PP +The +.I gzip +file format is specified in P.

See +.IR ln "(1)" +for more information. Use the +.B \-f +flag to force compression of multiply-linked files. +.SH CAVEATS +When writing compressed data to a tape, it is generally necessary to +pad the output with zeroes up to a block boundary. When the data is +read and the whole block is passed to +.I gunzip +for decompression, +.I gunzip +detects that there is extra trailing garbage after the compressed data +and emits a warning by default. You have to use the --quiet option to +suppress the warning. This option can be set in the +.B GZIP +environment variable as in: + for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0 + for csh: (setenv GZIP -q; tar -xfz --block-compr /dev/rst0 + +In the above example, gzip is invoked implicitly by the -z option of +GNU tar. Make sure that the same block size (-b option of tar) is used +for reading and writing compressed data on tapes. (This example +assumes you are using the GNU version of tar.) +.SH BUGS +The gzip format represents the input size modulo 2^32, so the +--list option reports incorrect uncompressed sizes and compression +ratios for uncompressed files 4 GB and larger. To work around this +problem, you can use the following command to discover a large +uncompressed file's true size: + + zcat file.gz | wc -c + +The --list option reports sizes as -1 and crc as ffffffff if the +compressed file is on a non seekable media. + +In some rare cases, the --best option gives worse compression than +the default compression level (-6).

Whenever possible, each file is replaced by one with the + extension .gz, while keeping the same ownership modes, access and modi- + fication times. (The default extension is -gz for VMS, z for MSDOS, + OS/2 FAT, Windows NT FAT and Atari.) If no files are specified, or if + a file name is "-", the standard input is compressed to the standard + output. Gzip will only attempt to compress regular files. In particu- + lar, it will ignore symbolic links. + + If the compressed file name is too long for its file system, gzip trun- + cates it. Gzip attempts to truncate only the parts of the file name + longer than 3 characters. (A part is delimited by dots.) If the name + consists of small parts only, the longest parts are truncated. For + example, if file names are limited to 14 characters, gzip.msdos.exe is + compressed to gzi.msd.exe.gz. Names are not truncated on systems which + do not have a limit on file name length. + + By default, gzip keeps the original file name and timestamp in the com- + pressed file. These are used when decompressing the file with the -N + option. This is useful when the compressed file name was truncated or + when the time stamp was not preserved after a file transfer. + + Compressed files can be restored to their original form using gzip -d + or gunzip or zcat. If the original name saved in the compressed file + is not suitable for its file system, a new name is constructed from the + original one to make it legal. + + gunzip takes a list of files on its command line and replaces each file + whose name ends with .gz, -gz, .z, -z, _z or .Z and which begins with + the correct magic number with an uncompressed file without the original + extension. gunzip also recognizes the special extensions .tgz and .taz + as shorthands for .tar.gz and .tar.Z respectively. When compressing, + gzip uses the .tgz extension if necessary instead of truncating a file + with a .tar extension. + + gunzip can currently decompress files created by gzip, zip, compress, + compress -H or pack. The detection of the input format is automatic. + When using the first two formats, gunzip checks a 32 bit CRC. For pack, + gunzip checks the uncompressed length. The standard compress format was + not designed to allow consistency checks. However gunzip is sometimes + able to detect a bad .Z file. If you get an error when uncompressing a + .Z file, do not assume that the .Z file is correct simply because the + standard uncompress does not complain. This generally means that the + standard uncompress does not check its input, and happily generates + garbage output. The SCO compress -H format (lzh compression method) + does not include a CRC but also allows some consistency checks. + + Files created by zip can be uncompressed by gzip only if they have a + single member compressed with the 'deflation' method. This feature is + only intended to help conversion of tar.zip files to the tar.gz format. + To extract a zip file with a single member, use a command like gunzip + , Inter- + net RFC 1952 (May 1996). The zip deflation format is specified in P. + Deutsch, DEFLATE Compressed Data Format Specification version 1.3, + , Internet RFC 1951 (May 1996). + +OPTIONS + -a --ascii + Ascii text mode: convert end-of-lines using local conventions. + This option is supported only on some non-Unix systems. For + MSDOS, CR LF is converted to LF when compressing, and LF is con- + verted to CR LF when decompressing. + + -c --stdout --to-stdout + Write output on standard output; keep original files unchanged. + If there are several input files, the output consists of a + sequence of independently compressed members. To obtain better + compression, concatenate all input files before compressing + them. + + -d --decompress --uncompress + Decompress. + + -f --force + Force compression or decompression even if the file has multiple + links or the corresponding file already exists, or if the com- + pressed data is read from or written to a terminal. If the input + data is not in a format recognized by gzip, and if the option + --stdout is also given, copy the input data without change to + the standard output: let zcat behave as cat. If -f is not + given, and when not running in the background, gzip prompts to + verify whether an existing file should be overwritten. + + -h --help + Display a help screen and quit. + + -l --list + For each compressed file, list the following fields: + + compressed size: size of the compressed file + uncompressed size: size of the uncompressed file + ratio: compression ratio (0.0% if unknown) + uncompressed_name: name of the uncompressed file + + The uncompressed size is given as -1 for files not in gzip for- + mat, such as compressed .Z files. To get the uncompressed size + for such a file, you can use: + + zcat file.Z | wc -c + + In combination with the --verbose option, the following fields + are also displayed: + + method: compression method + crc: the 32-bit CRC of the uncompressed data + date & time: time stamp for the uncompressed file + + The compression methods currently supported are deflate, com- + press, lzh (SCO compress -H) and pack. The crc is given as + ffffffff for a file not in gzip format. + + With --name, the uncompressed name, date and time are those + stored within the compress file if present. + + With --verbose, the size totals and compression ratio for all + files is also displayed, unless some sizes are unknown. With + --quiet, the title and totals lines are not displayed. + + -L --license + Display the gzip license and quit. + + -n --no-name + When compressing, do not save the original file name and time + stamp by default. (The original name is always saved if the name + had to be truncated.) When decompressing, do not restore the + original file name if present (remove only the gzip suffix from + the compressed file name) and do not restore the original time + stamp if present (copy it from the compressed file). This option + is the default when decompressing. + + -N --name + When compressing, always save the original file name and time + stamp; this is the default. When decompressing, restore the + original file name and time stamp if present. This option is + useful on systems which have a limit on file name length or when + the time stamp has been lost after a file transfer. + + -q --quiet + Suppress all warnings. + + -r --recursive + Travel the directory structure recursively. If any of the file + names specified on the command line are directories, gzip will + descend into the directory and compress all the files it finds + there (or decompress them in the case of gunzip ). + + -S .suf --suffix .suf + Use suffix .suf instead of .gz. Any suffix can be given, but + suffixes other than .z and .gz should be avoided to avoid confu- + sion when files are transferred to other systems. A null suffix + forces gunzip to try decompression on all given files regard- + less of suffix, as in: + + gunzip -S "" * (*.* for MSDOS) + + Previous versions of gzip used the .z suffix.

The default compression + level is -6 (that is, biased towards high compression at expense + of speed). + +ADVANCED USAGE + Multiple compressed files can be concatenated. In this case, gunzip + will extract all members at once. For example: + + gzip -c file1 > foo.gz + gzip -c file2 >> foo.gz + + Then + + gunzip -c foo + + is equivalent to + + cat file1 file2 + + In case of damage to one member of a .gz file, other members can still + be recovered (if the damaged member is removed). However, you can get + better compression by compressing all members at once: + + cat file1 file2 | gzip > foo.gz + + compresses better than + + gzip -c file1 file2 > foo.gz + + If you want to recompress concatenated files to get better compression, + do: + + gzip -cd old.gz | gzip > new.gz + + If a compressed file consists of several members, the uncompressed size + and CRC reported by the --list option applies to the last member only. + If you need the uncompressed size for all members, you can use: + + gzip -cd file.gz | wc -c + + If you wish to create a single archive file with multiple members so + that members can later be extracted independently, use an archiver such + as tar or zip. GNU tar supports the -z option to invoke gzip transpar- + ently. gzip is designed as a complement to tar, not as a replacement. + +ENVIRONMENT + The environment variable GZIP can hold a set of default options for + gzip. These options are interpreted first and can be overwritten by + explicit command line parameters. For example: + for sh: GZIP="-8v --name"; export GZIP + for csh: setenv GZIP "-8v --name" + for MSDOS: set GZIP=-8v --name + + On Vax/VMS, the name of the environment variable is GZIP_OPT, to avoid + a conflict with the symbol set for invocation of the program. + +SEE ALSO + znew(1), zcmp(1), zmore(1), zforce(1), gzexe(1), zip(1), unzip(1), com- + press(1), pack(1), compact(1) + + The gzip file format is specified in P.

See ln(1) for + more information. Use the -f flag to force compression of multi- + ply-linked files. + +CAVEATS + When writing compressed data to a tape, it is generally necessary to + pad the output with zeroes up to a block boundary. When the data is + read and the whole block is passed to gunzip for decompression, gunzip + detects that there is extra trailing garbage after the compressed data + and emits a warning by default. You have to use the --quiet option to + suppress the warning. This option can be set in the GZIP environment + variable as in: + for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0 + for csh: (setenv GZIP -q; tar -xfz --block-compr /dev/rst0 + + In the above example, gzip is invoked implicitly by the -z option of + GNU tar. Make sure that the same block size (-b option of tar) is used + for reading and writing compressed data on tapes. (This example + assumes you are using the GNU version of tar.) + +BUGS + The gzip format represents the input size modulo 2^32, so the --list + option reports incorrect uncompressed sizes and compression ratios for + uncompressed files 4 GB and larger. To work around this problem, you + can use the following command to discover a large uncompressed file's + true size: + + zcat file.gz | wc -c + + The --list option reports sizes as -1 and crc as ffffffff if the com- + pressed file is on a non seekable media. + + In some rare cases, the --best option gives worse compression than the + default compression level (-6).

The compression + method searches for as much of the current string of bytes (up to a + length of 258) in the previous 32K bytes. If it doesn't find any + matches (of at least length 3), it codes the next byte. Otherwise, it + codes the length of the matched string and its distance backwards from + the current position. There is a single Huffman code that codes both + single bytes (called "literals") and match lengths. A second Huffman + code codes the distance information, which follows a length code. Each + length or distance code actually represents a base value and a number + of "extra" (sometimes zero) bits to get to add to the base value. At + the end of each deflated block is a special end-of-block (EOB) literal/ + length code. The decoding process is basically: get a literal/length + code; if EOB then done; if a literal, emit the decoded byte; if a + length then get the distance and emit the referred-to bytes from the + sliding window of previously emitted data. + + There are (currently) three kinds of inflate blocks: stored, fixed, and + dynamic. The compressor deals with some chunk of data at a time, and + decides which method to use on a chunk-by-chunk basis. A chunk might + typically be 32K or 64K. If the chunk is uncompressible, then the + "stored" method is used. In this case, the bytes are simply stored as + is, eight bits per byte, with none of the above coding. The bytes are + preceded by a count, since there is no longer an EOB code. + + If the data is compressible, then either the fixed or dynamic methods + are used. In the dynamic method, the compressed data is preceded by + an encoding of the literal/length and distance Huffman codes that are + to be used to decode this block. The representation is itself Huffman + coded, and so is preceded by a description of that code. These code + descriptions take up a little space, and so for small blocks, there is + a predefined set of codes, called the fixed codes. The fixed method is + used if the block codes up smaller that way (usually for quite small + chunks), otherwise the dynamic method is used. In the latter case, the + codes are customized to the probabilities in the current block, and so + can code it much better than the pre-determined fixed codes. + + The Huffman codes themselves are decoded using a multi-level table + lookup, in order to maximize the speed of decoding plus the speed of + building the decoding tables. See the comments below that precede the + lbits and dbits tuning parameters. + */ + + +/* + Notes beyond the 1.93a appnote.txt: + + 1. Distance pointers never point before the beginning of the output + stream. + 2. Distance pointers can point back across blocks, up to 32k away. + 3. There is an implied maximum of 7 bits for the bit length table and + 15 bits for the actual data. + 4. If only one code exists, then it is encoded using one bit. (Zero + would be more efficient, but perhaps a little confusing.) If two + codes exist, they are coded using one bit each (0 and 1). + 5. There is no way of sending zero distance codes--a dummy must be + sent if there are none. (History: a pre 2.0 version of PKZIP would + store blocks with no distance codes, but this was discovered to be + too harsh a criterion.) Valid only for 1.93a. 2.04c does allow + zero distance codes, which is sent as one code of zero bits in + length. + 6. There are up to 286 literal/length codes. Code 256 represents the + end-of-block. Note however that the static length tree defines + 288 codes just to fill out the Huffman codes. Codes 286 and 287 + cannot be used though, since there is no length base or extra bits + defined for them. Similarly, there are up to 30 distance codes. + However, static trees define 32 codes (all 5 bits) to fill out the + Huffman codes, but the last two had better not show up in the data. + 7. Unzip can check dynamic Huffman blocks for complete code sets. + The exception is that a single code would not be complete (see #4). + 8. The five bits following the block type is really the number of + literal codes sent minus 257. + 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits + (1+6+6). Therefore, to output three times the length, you output + three codes (1+1+1), whereas to output four times the same length, + you only need two codes (1+3). Hmm. + 10. In the tree reconstruction algorithm, Code = Code + Increment + only if BitLength(i) is not zero. (Pretty obvious.) + 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) + 12. Note: length code 284 can represent 227-258, but length code 285 + really is 258. The last length deserves its own, short code + since it gets used a lot in very redundant files. The length + 258 is special since 258 - 3 (the min match length) is 255. + 13. The literal/length and distance code bit lengths are read as a + single stream of lengths. It is possible (and advantageous) for + a repeat code (16, 17, or 18) to go across the boundary between + the two sets of lengths. + */ + +#ifdef RCSID +static char rcsid[] = "$Id: inflate.c,v 1.6 2006/12/20 23:30:17 eggert Exp $"; +#endif + +#include +#include "tailor.h" + +#if defined STDC_HEADERS || defined HAVE_STDLIB_H +# include +#endif + +#include "gzip.h" +#define slide window + +/* Huffman code lookup table entry--this entry is four bytes for machines + that have 16-bit pointers (e.g. PC's in the small or medium model). + Valid extra bits are 0..13. e == 15 is EOB (end of block), e == 16 + means that v is a literal, 16 < e < 32 means that v is a pointer to + the next table, which codes e - 16 bits, and lastly e == 99 indicates + an unused code.

The idea is you can have a shorter table that decodes the + shorter, more probable codes, and then point to subsidiary tables for + the longer codes. The time it costs to decode the longer codes is + then traded against the time it takes to make longer tables. + + This results of this trade are in the variables lbits and dbits + below. lbits is the number of bits the first level table for literal/ + length codes can decode in one step, and dbits is the same thing for + the distance codes. Subsequent tables are also less than or equal to + those sizes. These values may be adjusted either when all of the + codes are shorter than that, in which case the longest code length in + bits is used, or when the shortest code is *longer* than the requested + table size, in which case the length of the shortest code in bits is + used. + + There are two different values for the two tables, since they code a + different number of possibilities each.

Whenever possible, each file is replaced by + one with the extension .gz, while keeping the same ownership + modes, access and modification times. (The default exten- + sion is -gz for VMS, z for MSDOS, OS/2 FAT, Windows NT FAT + and Atari.) If no files are specified, or if a file name is + "-", the standard input is compressed to the standard out- + put. Gzip will only attempt to compress regular files. + + If the compressed file name is too long for its file system, + gzip truncates it. Gzip attempts to truncate only the parts + of the file name longer than 3 characters. (A part is del- + imited by dots.) If the name consists of small parts only, + the longest parts are truncated. For example, if file names + are limited to 14 characters, gzip.msdos.exe is compressed + to gzi.msd.exe.gz. Names are not truncated on systems which + do not have a limit on file name length. + + By default, gzip keeps the original file name and timestamp + in the compressed file. These are used when decompressing + the file with the -N option. This is useful when the + compressed file name was truncated or when the time stamp + was not preserved after a file transfer. + + Compressed files can be restored to their original form + using gzip -d or gunzip or zcat. If the original name saved + in the compressed file is not suitable for its file system, + a new name is constructed from the original one to make it + legal. + + gunzip takes a list of files on its command line and + replaces each file whose name ends with .gz, -gz, .z, -z, _z + or .Z and which begins with the correct magic number with an + uncompressed file without the original extension. gunzip + also recognizes the special extensions .tgz and .taz as + shorthands for .tar.gz and .tar.Z respectively. When + compressing, gzip uses the .tgz extension if necessary + instead of truncating a file with a .tar extension. + + gunzip can currently decompress files created by gzip, zip, + compress, compress -H or pack. The detection of the input + format is automatic. When using the first two formats, + gunzip checks a 32 bit CRC. For pack, gunzip checks the + uncompressed length. The standard compress format was not + designed to allow consistency checks. However gunzip is + sometimes able to detect a bad .Z file. If you get an error + when uncompressing a .Z file, do not assume that the .Z file + is correct simply because the standard uncompress does not + complain. This generally means that the standard uncompress + does not check its input, and happily generates garbage out- + put. The SCO compress -H format (lzh compression method) + does not include a CRC but also allows some consistency + checks. + + Files created by zip can be uncompressed by gzip only if + they have a single member compressed with the 'deflation' + method. This feature is only intended to help conversion of + tar.zip files to the tar.gz format. To extract zip files + with several members, use unzip instead of gunzip. + + zcat is identical to gunzip -c. (On some systems, zcat may + be installed as gzcat to preserve the original link to + compress.) zcat uncompresses either a list of files on the + command line or its standard input and writes the + uncompressed data on standard output. zcat will uncompress + files that have the correct magic number whether they have a + .gz suffix or not. + + Gzip uses the Lempel-Ziv algorithm used in zip and PKZIP. + The amount of compression obtained depends on the size of + the input and the distribution of common substrings. Typi- + cally, text such as source code or English is reduced by + 60-70%. Compression is generally much better than that + achieved by LZW (as used in compress), Huffman coding (as + used in pack), or adaptive Huffman coding (compact). + + Compression is always performed, even if the compressed file + is slightly larger than the original. The worst case expan- + sion is a few bytes for the gzip file header, plus 5 bytes + every 32K block, or an expansion ratio of 0.015% for large + files. Note that the actual number of used disk blocks + almost never increases. gzip preserves the mode, ownership + and timestamps of files when compressing or decompressing. + +2 OPTIONS + -a --ascii + Ascii text mode: convert end-of-lines using local con- + ventions. This option is supported only on some non- + Unix systems. For MSDOS, CR LF is converted to LF when + compressing, and LF is converted to CR LF when + decompressing. + + -c --stdout --to-stdout + Write output on standard output; keep original files + unchanged. If there are several input files, the out- + put consists of a sequence of independently compressed + members. To obtain better compression, concatenate all + input files before compressing them. + + -d --decompress --uncompress + Decompress. + + -f --force + Force compression or decompression even if the file has + multiple links or the corresponding file already + exists, or if the compressed data is read from or writ- + ten to a terminal. If the input data is not in a format + recognized by gzip, and if the option --stdout is also + given, copy the input data without change to the stan- + dard output: let zcat behave as cat. If -f is not given, + and when not running in the background, gzip prompts to + verify whether an existing file should be overwritten. + + -h --help + Display a help screen and quit. + + -l --list + For each compressed file, list the following fields: + + compressed size: size of the compressed file + uncompressed size: size of the uncompressed file + ratio: compression ratio (0.0% if unknown) + uncompressed_name: name of the uncompressed file + + The uncompressed size is given as -1 on VMS because it + it is not possible to seek reliably to the end of the + compressed file, where this size is stored. + + In combination with the --verbose option, the following + fields are also displayed: + + method: compression method + crc: the 32-bit CRC of the uncompressed data + date & time: time stamp for the uncompressed file + + The compression methods currently supported are + deflate, compress, lzh (SCO compress -H) and pack. The + crc is given as ffffffff on VMS for the reason given + above about the uncompressed size. + + With --name, the uncompressed name, date and time are + those stored within the compress file if present. + + With --verbose, the size totals and compression ratio + for all files is also displayed, unless some sizes are + unknown. With --quiet, the title and totals lines are + not displayed. + + -L --license + Display the gzip license and quit. + + -n --no-name + When compressing, do not save the original file name + and time stamp by default. (The original name is always + saved if the name had to be truncated.) When + decompressing, do not restore the original file name if + present (remove only the gzip suffix from the + compressed file name) and do not restore the original + time stamp if present (copy it from the compressed + file). This option is the default when decompressing. + + -N --name + When compressing, always save the original file name + and time stamp; this is the default. When decompress- + ing, restore the original file name and time stamp if + present. This option is useful on systems which have a + limit on file name length or when the time stamp has + been lost after a file transfer. + + -q --quiet + Suppress all warnings. + + -r --recursive + Travel the directory structure recursively. If any of + the file names specified on the command line are direc- + tories, gzip will descend into the directory and + compress all the files it finds there (or decompress + them in the case of gunzip ). + + -S suf --suffix suf + Use suffix suf instead of -gz. Any suffix can be + given, but suffixes other than -z and -gz should be + avoided to avoid confusion when files are transferred + to other. A null suffix forces gunzip to try + decompression on all given files regardless of suffix, + as in: + + gunzip --suffix "" *.* + + Previous versions of gzip used the -z suffix. This was + changed to avoid a conflict with pack on Unix. + + -t --test + Test. Check the compressed file integrity. + + -v --verbose + Verbose.

The default compression level is -6 (that is, + biased towards high compression at expense of speed). + +2 ENVIRONMENT + The environment variable GZIP_OPT can hold a set of default + options for gzip.

You can use a + separate utility to restore the original format. + - gunzip and zcat can be used only if you have created the + links to gzip as documented in makegzip.com. Otherwise + you must use explicit parameters ("gzip -c" or "gzip -dc"). + - gzip --list cannot give the uncompressed size and crc. + + When writing compressed data to a tape, it is generally + necessary to pad the output with zeroes up to a block boun- + dary. When the data is read and the whole block is passed to + gunzip for decompression, gunzip detects that there is extra + trailing garbage after the compressed data and emits a warn- + ing by default. You have to use the --quiet option to + suppress the warning. This option can be set in the GZIP_OPT + environment variable as in: + define GZIP_OPT "-q" + +2 BUGS + On VMS, files in VFC record format are not correctly handled by + the C runtime library (the linefeed character is suppressed). + + In some rare cases, the --best option gives worse compres- + sion than the default compression level (-6). On some highly + redundant files, compress compresses better than gzip. diff --git a/vms/makegzip.com b/vms/makegzip.com new file mode 100644 index 0000000..def90f6 --- /dev/null +++ b/vms/makegzip.com @@ -0,0 +1,71 @@ +$!
