My Bash Prompt

Note: this is republished from my blog and slightly out of date in that I now mostly use Fish but don't have a fun prompt yet.

Bash Prompt Example

I recently updated my Bash prompt. It started because I wanted to incorporate git status information into the prompt. But once I got that working it turned out I didn't really like it so I ditched it but kept the other stuff I did.

Here's the relevant portion from my .bashrc:

# Prompt
gen_prompt() {
    ## Looks like:
    ## ╭─┤pty0├─╢mark@bender:~/src╟─┤(✿◠‿◠)├─╮
    ## ╰>
    local __last_exit=$?
    [[ -f ~/.colors ]] && source ~/.colors

    local __line_color=${Red}
    local __prompt_color=${White}
    local __text_color=${White}

    local __success_string="${Green}(✿◠‿◠)"
    local __failure_string="${Red}(◡﹏◡✿)"
    local __exit_string=$(if [[ $__last_exit -ne 0 ]]; then echo $__failure_string; else echo $__success_string; fi)
    local __prompt="> "

    PS1="\n${__line_color}╭─┤${__text_color}\l${__line_color}├─╢${__text_color}\u@\h:\w${__line_color}╟─┤${__exit_string}${__line_color}├─╮\n${__prompt}\[$(tput sgr0)\]"
}
export PROMPT_COMMAND=gen_prompt

Here's colors if you want the color commands to work (save to ~/.colors):
