fish_prompt - define the appearance of the command line prompt

Synopsis

function fish_prompt
    ...
end

Description

By defining the fish_prompt function, the user can choose a custom prompt. 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 outside of the fish_prompt function.

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"
    printf '%s@%s%s%s%s> ' (whoami) (hostname | cut -d . -f 1) \
                    (set_color $fish_color_cwd) (prompt_pwd) (set_color normal)
end
