Follow these instructions to start using Zsh:
https://github.com/robbyrussell/oh-my-zsh
I'm using the Agnoster theme:
https://github.com/agnoster/agnoster-zsh-theme
You'll have to install the Patched Solarized Fonts:
https://github.com/powerline/fonts
Change iTerm to use the new fonts:
iTerm2 users need to set both the Regular font and the Non-ASCII Font in "iTerm > Preferences > Text" to use a patched font
I have it show only the last two directories from wherever PWD is (instead of the whole path from ~), so, in line 189 of the theme, change
prompt_segment blue black to use:
prompt_dir() {
prompt_segment blue black '%2~'
}ZSH has a lot of other oddities, including making it play well with .bashrc to pick up old aliases, etc, but I've been using it for a few months and really like it.
