- c\bcd\bd [-\b-L\bL|[-\b-P\bP [-\b-e\be]]] [_\bd_\bi_\br]
- Change the current directory to _\bd_\bi_\br. The variable H\bHO\bOM\bME\bE is the
- default _\bd_\bi_\br. The variable C\bCD\bDP\bPA\bAT\bTH\bH defines the search path for
- the directory containing _\bd_\bi_\br. Alternative directory names in
- C\bCD\bDP\bPA\bAT\bTH\bH are separated by a colon (:). A null directory name in
- C\bCD\bDP\bPA\bAT\bTH\bH is the same as the current directory, i.e., ``.\b.''. If
- _\bd_\bi_\br begins with a slash (/), then C\bCD\bDP\bPA\bAT\bTH\bH is not used. The -\b-P\bP
- option says to use the physical directory structure instead of
- following symbolic links (see also the -\b-P\bP option to the s\bse\bet\bt
- builtin command); the -\b-L\bL option forces symbolic links to be fol-
- lowed. If the -\b-e\be option is supplied with -\b-P\bP, and the current
- working directory cannot be successfully determined after a suc-
- cessful directory change, c\bcd\bd will return an unsuccessful status.
- An argument of -\b- is equivalent to $\b$O\bOL\bLD\bDP\bPW\bWD\bD. If a non-empty
- directory name from C\bCD\bDP\bPA\bAT\bTH\bH is used, or if -\b- is the first argu-
- ment, and the directory change is successful, the absolute path-
- name of the new working directory is written to the standard
- output. The return value is true if the directory was success-
- fully changed; false otherwise.
+ c\bcd\bd [-\b-L\bL|[-\b-P\bP [-\b-e\be]] [-@]] [_\bd_\bi_\br]
+ Change the current directory to _\bd_\bi_\br. if _\bd_\bi_\br is not supplied,
+ the value of the H\bHO\bOM\bME\bE shell variable is the default. Any addi-
+ tional arguments following _\bd_\bi_\br are ignored. The variable C\bCD\bDP\bPA\bAT\bTH\bH
+ defines the search path for the directory containing _\bd_\bi_\br: each
+ directory name in C\bCD\bDP\bPA\bAT\bTH\bH is searched for _\bd_\bi_\br. Alternative
+ directory names in C\bCD\bDP\bPA\bAT\bTH\bH are separated by a colon (:). A null
+ directory name in C\bCD\bDP\bPA\bAT\bTH\bH is the same as the current directory,
+ i.e., ``.\b.''. If _\bd_\bi_\br begins with a slash (/), then C\bCD\bDP\bPA\bAT\bTH\bH is not
+ used. The -\b-P\bP option causes c\bcd\bd to use the physical directory
+ structure by resolving symbolic links while traversing _\bd_\bi_\br and
+ before processing instances of _\b._\b. in _\bd_\bi_\br (see also the -\b-P\bP option
+ to the s\bse\bet\bt builtin command); the -\b-L\bL option forces symbolic links
+ to be followed by resolving the link after processing instances
+ of _\b._\b. in _\bd_\bi_\br. If _\b._\b. appears in _\bd_\bi_\br, it is processed by removing
+ the immediately previous pathname component from _\bd_\bi_\br, back to a
+ slash or the beginning of _\bd_\bi_\br. If the -\b-e\be option is supplied
+ with -\b-P\bP, and the current working directory cannot be success-
+ fully determined after a successful directory change, c\bcd\bd will
+ return an unsuccessful status. On systems that support it, the
+ -\b-@\b@ option presents the extended attributes associated with a
+ file as a directory. An argument of -\b- is converted to $\b$O\bOL\bLD\bDP\bPW\bWD\bD
+ before the directory change is attempted. If a non-empty direc-
+ tory name from C\bCD\bDP\bPA\bAT\bTH\bH is used, or if -\b- is the first argument,
+ and the directory change is successful, the absolute pathname of
+ the new working directory is written to the standard output.
+ The return value is true if the directory was successfully
+ changed; false otherwise.
