FISH(1)

NAME
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. This page briefly describes the options for invoking fish. The full manual is available in HTML by using the help command from inside fish, and in the fish-doc(1) man page. The tutorial is available as HTML via help tutorial or in fish-tutorial(1).

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, including categories and fish_trace. 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

•   -P or --private enables private mode, so fish will not access old or store new history.

•   --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.
