command - run a program




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 COMMANDNAMEs that are found in $PATH in the order they are found.
  • -q or --quiet, silences the output and prints nothing, setting only the exit status. 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.


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.
