====== The cd builtin command ======
|
||
|
|
|
||
|
|
===== Synopsis =====
|
||
|
|
<code>cd [-L|-P] [DIRECTORY]</code>
|
||
|
|
<code>cd -</code>
|
||
|
|
|
||
|
|
===== Description =====
|
||
|
|
The ''cd'' builtin command is used to change the current working directory
|
||
|
|
* to the given directory (''cd DIRECTORY'')
|
||
|
|
* to the previous working directory (''cd -'') as saved in the [[syntax:shellvars#OLDPWD|OLDPWD]] shell variable
|
||
|
|
* to the user's home directory as specified in the [[syntax:shellvars#HOME|HOME]] environment variable (when used without a ''DIRECTORY'' argument)
|
||
|
|
|
||
|
|
The ''cd'' builtin command searches the directories listed in [[syntax:shellvars#CDPATH|CDPATH]] for a matching directory.
|
||
|
|
|
||
|
|
The default behaviour is to follow symbolic links unless the ''-P'' option is given or the shell is configured to do so (see the ''-P'' option of [[commands:builtin:set|the set builtin command]]).
|
||
|
|
|
||
|
|
==== Options ====
|
||
|
|
|
||
|
|
^Option^Description^

|
||
|
|
|''-@'' |Browse a file's extended attributed, if supported |
|
||
|
|
|
||
|
|
==== Exit status ====
|
||
|
|
|
||
|
|
* true if the directory was changed successfully
|
||
|
|
* false if a change to the home directory was requested, but [[syntax:shellvars#HOME|HOME]] is unset
|
||
|
|
* false if anything else goes wrong
|
||
|
|
|
