# fish_title - define the terminal’s title

## Synopsis

    fish_title

    function fish_title
        ...
    end

## Description

The `fish_title` function is executed before and after a new command is executed or put into the foreground and the output is used as a titlebar message.

The first argument to fish_title contains the most recently executed foreground command as a string, if any.

This requires that your terminal supports programmable titles and the feature is turned on.

## Example

A simple title:

    function fish_title
        set -q argv[1]; or set argv fish
        # Looks like ~/d/fish: git log
        # or /e/apt: fish
        echo (fish_prompt_pwd_dir_length=1 prompt_pwd): $argv;
    end
