FISH_PROMPT(1)

NAME
fish_prompt - define the appearance of the command line prompt

SYNOPSIS
fish_prompt

    function fish_prompt
        ...
    end

DESCRIPTION

The fish_prompt function is executed when the prompt is to be shown, and the output is used as a prompt.

The exit status of commands within fish_prompt will not modify the value of $status <#variables-status> outside of the fish_prompt function.

If fish_transient_prompt <#envvar-fish_transient_prompt> is set to 1, fish_prompt --final-rendering is run before executing the commandline.

If SHELL_PROMPT_PREFIX <#envvar-SHELL_PROMPT_PREFIX> or SHELL_PROMPT_SUFFIX <#envvar-SHELL_PROMPT_SUFFIX> are set, they are automatically prepended and appended to the left prompt. This applies to all prompts regardless of whether fish_prompt has been customized.

fish ships with a number of example prompts that can be chosen with the fish_config command.

EXAMPLE

A simple prompt:

    function fish_prompt -d "Write out the prompt"
        # This shows up as USER@HOST /home/user/ >, with the directory colored
        # $USER and $hostname are set by fish, so you can just use them
        # instead of using `whoami` and `hostname`
        printf '%s@%s %s%s%s > ' $USER $hostname \
            (set_color $fish_color_cwd) (prompt_pwd) (set_color --reset)
    end
