.. _cmd-fish:
fish - the friendly interactive shell
=====================================
Synopsis
--------
fish [OPTIONS] [-c command] [FILE [ARGUMENTS...]]
Description
-----------
``fish`` is a command-line shell written mainly with interactive use in mind. The :ref:`full manual <intro>` is available in HTML by using the :ref:`help <cmd-help>` command from inside fish.
The following options are available:
- ``-c`` or ``--command=COMMANDS`` evaluate the specified commands instead of reading from the commandline
- ``-C`` or ``--init-command=COMMANDS`` evaluate the specified commands after reading the configuration, before running the command specified by ``-c`` or reading interactive input
- ``-d`` or ``--debug=CATEGORY_GLOB`` enables debug output and specifies a glob for matching debug categories (like ``fish -d``). Defaults to empty.
- ``-o`` or ``--debug-output=path`` Specify a file path to receive the debug output. The default is stderr.
- ``-i`` or ``--interactive`` specify that fish is to run in interactive mode
- ``-l`` or ``--login`` specify that fish is to run as a login shell
- ``-n`` or ``--no-execute`` do not execute any commands, only perform syntax checking
- ``-p`` or ``--profile=PROFILE_FILE`` when fish exits, output timing information on all executed commands to the specified file
- ``--print-rusage-self`` when fish exits, output stats from getrusage
- ``--print-debug-categories`` outputs the list of debug categories, and then exits.
- ``-v`` or ``--version`` display version and exit
- ``-D`` or ``--debug-stack-frames=DEBUG_LEVEL`` specify how many stack frames to display when debug messages are written. The default is zero. A value of 3 or 4 is usually sufficient to gain insight into how a given debug call was reached but you can specify a value up to 128.
- ``-f`` or ``--features=FEATURES`` enables one or more feature flags (separated by a comma). These are how fish stages changes that might break scripts.
The fish exit status is generally the exit status of the last foreground command. If fish is exiting because of a parse error, the exit status is 127.
