When writing scripts for other shells, it can be confusing and annoying that our `man` function shadows other manual pages, for example `exec(1p)` from [Linux man-pages]. I almost never want to see the fish variant for such contended cases (which obviuosly don't include fish-specific commands like `string`, only widely-known shell builtins). For the contented cases like `exec`, the POSIX documentation is more substantial and useful, since it describes a (sub)set of languages widely used for scripting. Because of this I think we should stop overriding the system's man pages. Nowadays we offer `exec -h` as intuitive way to show the documentation for the fish-specific command (note that `help` is not a good replacement because it uses a web browser). Looking through the contended commands, it seems like for most of them, the fish version is not substantially different from the system version. A notable exception is `read` but I don't think it's a very important one. So I think we should can sacrifice a bit of the native fish-scripting experience in exchange for playing nicer with other shells. I think the latter is more important because scripting is not our focus, the way I see it. So maybe put our manpath at the end. In lieu of that, let's at least have `exec.rst` reference the system variant. [Linux man-pages]: https://www.kernel.org/doc/man-pages/ Closes #10376

Description

-----------

|
.. only:: builder_man
|
|
|
|
NOTE: This page documents the fish builtin ``cd``.
|
|
To see the documentation on any non-fish versions, use ``command man cd``.
|
|
|
|
``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 :doc:`prevd <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.
