git-completion

For the linux/mac users, there is a nice script available called git-completion that provides auto-completion of git commands, branch names and other helpful things. It also provides a way to display the active branch on your commandline prompt.

Download the appropriate git-completion script (https://github.com/git/git/tree/master/contrib/completion) and put it in your ~/bin folder. Then source this file in your .profile or .bash-profile. To add the active git branch to your prompt, set your PS1 setting (for the display prompt on a terminal) to something like this:

PS1='[\u@\h \w$(__git_ps1 " (%s)")]\$ '
