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

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
# Install Bash 4 using homebrew | |
brew install bash | |
# Or build it from source... | |
curl -O http://ftp.gnu.org/gnu/bash/bash-4.2.tar.gz | |
tar xzf bash-4.2.tar.gz | |
cd bash-4.2 | |
./configure --prefix=/usr/local/bin && make && sudo make install | |
