\subsection command-description 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`.

\subsection command-example 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.

Teach `command` builtin a -p/--path flag Give the `command` builtin a single flag, -p/--path, that causes it to print the full path that would be executed for the given command. 2014-07-10 09:21:06 +08:00			`The following options are available:`

implement `command -a` Fixes #2778 2017-06-24 06:42:38 +08:00			- `-a` or `--all` returns all the external commands that are found in `$PATH` in the order they are found.

Let `command -q` work This required "-sq" to be used and errored if just "-q" was given. Instead, if only "-q" is given, we behave just as if "-sq" was. 2019-02-09 19:51:55 +08:00			- `-q` or `--quiet`, silences the output and prints nothing, setting only the exit code. Implies `--search`.
