Customizing Shells

Bash

Customize Prompt

You can customize the Bash shell prompt by editing the PS1 variable in ~/.bashrc. For example, the current shell prompt is the following:

PS1="\e[1;32m┌──[HQ🚀🌐\e[1;31m$(ip -4 addr | grep -v '127.0.0.1' | grep -v 'secondary' | grep -oP '(?<=inet\s)\d+(\.\d+){3}' | sed -z 's/\n/|/g;s/|\$/\n/' | rev | cut -c 2- | rev)🔥\u\e[1;32m]\n└──╼[👾]\[\e[1;36m\]\$(pwd) $ \[\e[0m\]"

Note

The output colors could be affected by the current terminal theme. Furthermore, after \n, \[ characters have been used for wrapping the entire string for color: \[\e[36m\] and \[\e[0m\]. If this wrapping is not implemented, \n causes the shell to counts additional invisible character.

The emoji used on PS1 come from Emojipedia. For showing them on terminal, the noto-fonts-emoji package is needed.

Fish

Customize Prompt

You can customize the Fish shell prompt by editing ~/.config/fish/functions/fish_prompt.fish. For example, you can start to edit the shell prompt in Athena that is:

function fish_prompt
    set -l var (tty)
    switch $var
        case '*/dev/tty*'
            set_color 00ff00
            echo -n "[HQ:"
            set_color ff00d7
            echo -n "$(ip -4 addr | grep -v '127.0.0.1' | grep -v 'secondary' | grep -oP '(?<=inet\s)\d+(\.\d+){3}' |>
            echo -n " | $USER"
            set_color 00ff00
            echo "]"
            set_color 00ff00
            echo -n "[>]"
            set_color 00ffff
            echo (pwd) '$' (set_color normal)
        case '*'
            set_color 00ff00
            echo -n "┌──[HQ🚀🌐"
            set_color ff00d7
            echo -n "$(ip -4 addr | grep -v '127.0.0.1' | grep -v 'secondary' | grep -oP '(?<=inet\s)\d+(\.\d+){3}' |>
            echo -n "🔥$USER"
            set_color 00ff00
            echo "]"
            set_color 00ff00
            echo -n "└──╼[👾]"
            set_color 00ffff
            echo (pwd) '$' (set_color normal)
    end
    end

After saving the file, the shell will wait for something. Just close it.

For different colors, refer to the ANSI escape code web resouce and pass the mouse over the colors for getting the HEX code, for example:

set_color ff8700 -> Orange
set_color 00ff00 -> Green
set_color 00ffff -> Cyan
set_color ff00d7 -> Purple
set_color 123e7c -> Dark Blue

Zsh

Customize Prompt

You can customize the Zsh shell prompt by editing the PROMPT variable in ~/.zshrc. The Athena OS default shell prompt appears as:

PROMPT="%F{46}┌──[HQ🚀🌐%F{201}$(ip -4 addr | grep -v '127.0.0.1' | grep -v 'secondary' | grep -oP '(?<=inet\s)\d+(\.\d+){3}' | sed -z 's/\n/|/g;s/|\$/\n/' | rev | cut -c 2- | rev)🔥%n%F{46}]"$'\n'"└──╼[👾]%F{44}%~ $%f "

PowerShell

Customize Prompt

You can customize the PowerShell prompt by editing ~/.config/powershell/Microsoft.PowerShell_profile.ps1 and modifying its content:

function prompt()
{
  $ESC=$([char]27)
  "$ESC[1;31m┌──L3ts D0 1t $(whoami)💥$ESC[00m$($executionContext.SessionState.Path.CurrentLocation)$("`r`n$ESC[1;34m└──╼Weaponizing PowerShell...🚀>$ESC[00m" * ($nestedPromptLevel + 1)) ";
}

Switching Shell

If you have installed more than one shell and you wish to use mainly one, just edit the export SHELL= line in ~/.bashrc by adding the name of your favourite shell, for example:

export SHELL=$(which fish)
