Overview
Here is a little gem that will give you a more informative shell prompt as well as give you some ideas about how you can tweak your shell.
The prompt shows you a cool looking path, along with your current GiT branch.
...and is even nice enough to show you when you have a dirty branch, along with a nice little ✳ for when there are untracked files that might need to be added...
Usage
gem install promptula
promptula --install
Then source either your .bashrc or your .bash_profile, as appropriate
source ~/.bashrc
source ~/.bash_profile
...and that's it.
