FISH_TITLE(1)

NAME
fish_title - define the terminal's title

SYNOPSIS
fish_title
fish_tab_title

    function fish_title
        ...
    end
    function fish_tab_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 <#term-compat-osc-0> and the feature is turned on.

To disable setting the title, use an empty function (see below).

To set the terminal tab title to something other than the terminal window title, define the fish_tab_title function, which works like fish_title but overrides that one.

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

Do not change the title:

    function fish_title
    end

Change the tab title only:

    function fish_tab_title
        echo fish $fish_pid
    end
