If you want to enable tab auto complete at the command line on Mac OSX terminal, there is a handy auto-completion script you can use.

Using git-completion script to enable auto complete for GIT commands

1. 1. Download and save the git-completion script to your home directory

      curl https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash -o ~/.git-completion.bash

   2. Then open the .bash_profile file in your home directory

      vi ~/.bash_profile

   3. Add this at the end of .bash_profile

      if [ -f ~/.git-completion.bash ]; then
        . ~/.git-completion.bash
      fi

   4. Make the .git-completion.bash in your home directory executable

      chmod +x ~/.git-completion.bash

   5. Finally reload the .bash_profile with the following command, or just close and re open the shell and your git auto completion should be working.

      source ~/.bash_profile

The same method can be adapted to Centos6, Centos 7, Ubuntu, RHEL or any other bistro.
