Pimp My Prompt … like Paul Irish

The complete .bash_profile file

Here’s what my complete .bash_profile file looks like.  It’s got all the stuff above plus a couple of extra things e.g. setting my PATH, a couple of aliases for common commands I use and two extra PS1 prompt settings that you can use as reference, if you wish.

If you use any of the info in this post, please let me know by leaving a comment or using the contact form.  Thanks!

# set the prompt to show current working directory and git branch name, if it exists
