zsh your way to awesomeness

Mark my words. There will come a day when you'll hate getting out of your shell(If it hasn't already happened). Plain old bash would not be the right shell for you.

Make it display your git branch, status of your git repo, your ruby version.

Make your git prompt colored red if your last command fails. And green if it succeeds. Get better tab completion. Get tab completion on ssh.

ZSH is an interactive shell worth trying out. Check out this to learn how to customize zsh: https://github.com/robbyrussell/oh-my-zsh
