Note: this is republished from my blog and slightly out of date in that I now mostly use Fish but don't have a fun prompt yet.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