As part of my new new workflow, I'm also swithcing my shell, from Bash, to Zsh.
Bash has served me very well over the years, but its time a for a change. Having heard many good things about Zsh, I decided to take the plunge. The easiest and simplest way to get a working zsh shell is downloading oh-my-zsh by Robby Russell. It's very featured and has lots of plugins and themes. However, I've deceided to roll my own configuration using the already installing z-shell that comes with Mac OS X/Darwin. So, to start with:
chsh -s /bin/zsh
It's that simple, your previous bash profile is still available should you choose to switch back. I'll let you figure out how to that!
