• Start an interactive shell session:

fish

• Execute a command and then exit:

fish -c "{{command}}"

• Execute a script:

fish {{path/to/script.fish}}

• Check a script for syntax errors:

fish --no-execute {{path/to/script.fish}}

• Start an interactive shell session in private mode, where the shell does not access old history or save new history:

fish --private

• Display version information and exit:

fish --version

• Set and export environmental variables that persist across shell restarts (from within the shell only):

set -Ux {{variable_name}} {{variable_value}}
