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 ``command``.
|
|
To see the documentation on any non-fish versions, use ``command man command``.
|
|
|
|
**command** forces the shell to execute the program *COMMANDNAME* and ignore any functions or builtins with the same name.
|
|
|
|
In ``command foo``, ``command`` is a keyword.
|
|
|
|
The following options are available:
|
|
|
|
**-a** or **--all**
|
|
Prints all *COMMAND* found in :envvar:`PATH`, in the order found.
|
|
|
|
**-q** or **--query**
|
|
Return 0 if any of the given commands could be found, 127 otherwise.
|
|
Don't print anything.
|
|
For compatibility, this is also **--quiet** (deprecated).
|
|
|
|
**-s** or **--search** (or **-v**)
|
|
Prints the external command that would be executed, or prints nothing if no file with the specified name could be found in :envvar:`PATH`.
|
|
|
|
**-h** or **--help**
|
|
Displays help about using this command.

Examples
|
|
--------
|
|
|
|
| ``command ls`` executes the ``ls`` program, even if an ``ls`` function also exists.
|
|
| ``command -s ls`` prints the path to the ``ls`` program.
|
|
| ``command -q git; and command git log`` runs ``git log`` only if ``git`` exists.
|
|
| ``command -sq git`` and ``command -q git`` and ``command -vq git`` return true (0) if a git command could be found and don't print anything.
