You can use bash’s PROMPT_COMMAND to run a function which builds your prompt, e.g.:

PROMPT_COMMAND=build_prompt



build_prompt() {

  EXIT=$?               # save exit code of last command

  red='[e[0;31m]'    # colors

  green='[e[0;32m]'

  cyan='[e[1;36m]'

  reset='[e[0m]'

  PS1='${debian_chroot:+($debian_chroot)}'  # begin prompt



  if [ $EXIT != 0 ]; then  # add arrow color dependent on exit code

    PS1+="$red"

  else

    PS1+="$green"

  fi



  PS1+="→$reset  $cyanw$reset \$ " # construct rest of prompt

}

Add this code to your ~/.bashrc file and open a new terminal or run . ~/.bashrc in an existing one for the changes to take effect. Note that I added the usual $ at the end, this prints $ normally and # if you’re root, thus preventing you from running commands as root unwittingly. The false command is a good way to test the non-zero exit code variant:

If you’re into prompt themeing you should definitely take a look at the zsh shell (package zsh), whose famous configuration framework Oh My Zsh alone comes with over hundred themes. Additionally there are many other plugins available, for example the Spaceship ZSH prompt.
