    For Bash or Zsh, put something like this in your $HOME/.bashrc or $HOME/.zshrc:

     . `brew --prefix`/etc/profile.d/z.sh

     ZSH USERS BACKWARD COMPATIBILITY WARNING:
     z now handles 'precmd' set up for zsh. z (<=1.3) users using zsh should
     remove the precmd function that was described in the installation
     instructions for previous versions.

     In short, this:
        . /path/to/z.sh
        function precmd () {
         _z --add "$(pwd -P)"
        }
     should now just be:
        . `brew --prefix`/etc/profile.d/z.sh
    EOS
  end
