cd [DIRECTORY]
|
|
|
|
Description
|
|
-----------
|
|
``cd`` changes the current working directory.
|
|
|
|
If *DIRECTORY* is given, it will become the new directory. If no parameter is given, the :envvar:`HOME` environment variable will be used.
|
|
|
|
If *DIRECTORY* is a relative path, all the paths in the :envvar:`CDPATH` will be tried as prefixes for it, in addition to :envvar:`PWD`.
|
|
It is recommended to keep **.** as the first element of :envvar:`CDPATH`, or :envvar:`PWD` will be tried last.
|
|
|
|
Fish will also try to change directory if given a command that looks like a directory (starting with **.**, **/** or **~**, or ending with **/**), without explicitly requiring **cd**.
|
|
|
|
Fish also ships a wrapper function around the builtin **cd** that understands ``cd -`` as changing to the previous directory.
|
|
See also :ref:`prevd <cmd-prevd>`.
|
|
This wrapper function maintains a history of the 25 most recently visited directories in the ``$dirprev`` and ``$dirnext`` global variables.
|
|
If you make those universal variables your **cd** history is shared among all fish instances.
|
|
|
|
As a special case, ``cd .`` is equivalent to ``cd $PWD``, which is useful in cases where a mountpoint has been recycled or a directory has been removed and recreated.
|
|
|
|
The **--help** or **-h** option displays help about using this command, and does not change the directory.
