.. _cmd-fish_prompt:
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 <index.html#variables-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
