NAME

       fish - the friendly interactive shell

SYNOPSIS

       fish [OPTIONS] [FILE [ARG ...]]
       fish [OPTIONS] [-c COMMAND [ARG ...]]

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 man fish-tutorial.

       The following options are available:

       -c or --command=COMMAND
              Evaluate the specified commands instead of reading from  the  commandline,  passing
              additional positional arguments through $argv.

       -C or --init-command=COMMANDS
              Evaluate  specified  commands  after reading the configuration but before executing
              command specified by -c or reading interactive input.

       -d or --debug=DEBUG_CATEGORIES
              Enables debug output and specify a pattern  for  matching  debug  categories.   See
              Debugging below for details.

       -o or --debug-output=DEBUG_FILE
              Specifies  a  file  path  to  receive  the  debug  output, including categories and
              fish_trace.  The default is stderr.

       -i or --interactive
              The shell is interactive.

       -l or --login
              Act as if invoked as a login shell.

       -N or --no-config
              Do not read configuration files.

       -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.    This   excludes   time  spent  starting  up  and  reading  the
              configuration.

       --profile-startup=PROFILE_FILE
              Will write timing for fish startup to specified file.

       -P or --private
              Enables private mode: fish will not access old or store new history.

       --print-rusage-self
              When fish exits, output stats from getrusage.

       --print-debug-categories
              Print all debug categories, and then exit.

       -v or --version
              Print version and exit.

       -f or --features=FEATURES
              Enables one or more comma-separated feature flags.

       The fish exit status is generally the exit status of the last foreground command.

DEBUGGING

       While fish provides extensive support for debugging fish scripts, it is also  possible  to
       debug  and  instrument  its  internals.   Debugging  can be enabled by passing the --debug
       option.  For example, the following command turns on debugging for  background  IO  thread
       events,   in  addition  to  the  default  categories,  i.e.  debug,  error,  warning,  and
       warning-path:

          > fish --debug=iothread

       Available categories are listed  by  fish  --print-debug-categories.  The  --debug  option
       accepts  a  comma-separated  list  of categories, and supports glob syntax.  The following
       command turns on debugging for complete, history, history-file,  and  profile-history,  as
       well as the default categories:

          > fish --debug='complete,*history*'

       Debug  messages  output  to  stderr  by default. Note that if fish_trace is set, execution
       tracing also  outputs  to  stderr  by  default.  You  can  output  to  a  file  using  the
       --debug-output option:

          > fish --debug='complete,*history*' --debug-output=/tmp/fish.log --init-command='set fish_trace on'

       These options can also be changed via the FISH_DEBUG and FISH_DEBUG_OUTPUT variables.  The
       categories enabled via --debug are added to the ones enabled by $FISH_DEBUG, so  they  can
       be disabled by prefixing them with - (reader-*,-ast* enables reader debugging and disables
       ast debugging).

       The file given in --debug-output takes precedence over the file in FISH_DEBUG_OUTPUT.
