An agnoster and bullettrain inspired theme for ZSH
In order for this theme to render correctly, you will need a Powerline-patched font. Make sure you have a recent version: the code points that Powerline uses changed in 2012, and older versions will display incorrectly, in confusing ways.
In addition, I recommend the Solarized theme and, if you're using it on Mac OS X, iTerm 2 over Terminal.app - it has significantly better color fidelity.
cd $ZSH_CUSTOM
If theme folder exists skip this bit:
mkdir themes
cd themes
wget https://raw.githubusercontent.com/mikebell/bulletline/master/bulletline.zsh-theme
Modify ~/.zshrc and set ZSH_THEME="bulletline"
Credit should go to Agnoster mod and https://github.com/caiogondim for the hard work.
