command - run a program
|
|
=======================

Synopsis
|
|
--------
|
|
|
|
command [OPTIONS] COMMANDNAME [ARGS...]
|
|
|
|
|
|
Description
|
|
-----------
|
|
|
|
``command`` forces the shell to execute the program ``COMMANDNAME`` and ignore any functions or builtins with the same name.
|
|
|
|
The following options are available:
|
|
|
|
- ``-a`` or ``--all`` returns all the external commands that are found in ``$PATH`` in the order they are found.
|
|
|
|
- ``-q`` or ``--quiet``, silences the output and prints nothing, setting only the exit code. Implies ``--search``.
|
|
|
|
- ``-s`` or ``--search`` returns the name of the external command that would be executed, or nothing if no file with the specified name could be found in the ``$PATH``.
|
|
|
|
With the ``-s`` option, ``command`` treats every argument as a separate command to look up and sets the exit status to 0 if any of the specified commands were found, or 1 if no commands could be found. Additionally passing a ``-q`` or ``--quiet`` option prevents any paths from being printed, like ``type -q``, for testing only the exit status.
|
|
|
|
For basic compatibility with POSIX ``command``, the ``-v`` flag is recognized as an alias for ``-s``.

|
Examples
|
|
--------
|
|
|
|
``command ls`` causes fish to execute the ``ls`` program, even if an ``ls`` function exists.
|
|
|
|
``command -s ls`` returns the path to the ``ls`` program.
|
|
|
|
``command -q git; and command git log`` runs ``git log`` only if ``git`` exists.
