title: How can I debug the bash prompt?
body: <p>I've been editing <code>.bashrc</code> files and other init files, and it seems that I've left behind a few code snippets or two that are causing a few errors at the prompt (e.g. file missing), but I can't find them.</p>
  
  <p>How do I debug the prompt to find out what init scripts I've carelessly hacked?</p>
