title: Documentation for PS1 format
body: <p>I see lots of tutorials for adjusting the appearance of the prompt in bash (like <a href="http://www.cyberciti.biz/tips/howto-linux-unix-bash-shell-setup-prompt.html" rel="nofollow">here</a>), but where can I find the documentation for the format of the <code>PS1</code> variable?</p>
