Prereq:
apt-get install zsh
apt-get install git-core
Getting zsh to work in ubuntu is weird, since sh
does not understand the source
command. So, you do this to install zsh
wget --no-check-certificate http://install.ohmyz.sh -O - | sh
and then you change your shell to zsh
chsh -s `which zsh`
and then restart
sudo shutdown -r 0
