Add git branch to bash prompt

If you use git, you will find this small trick very useful.

To make your bash prompt super spiffy (and equally useful), add this to ~/.bashrc:

 #Adding git branch to command prompt
 gitStatus() { git diff --quiet 2> /dev/null || echo ' *' ; }

 gitBranch() { git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/* \(.*\)/ > \1$(gitStatus)/" ; }

Then, somewhere in your $PS1, put \$(gitBranch). Here's an example; try it:

      export PS1="[\u@\h$ \w\$(gitBranch)]\$ "

When you're in a git directory, you'll notice the branch name on the prompt. If the branch has been modified, an asterisk will appear next to the name. Here is an example :

My command prompt looks like this - 

cdump@cdump-linux : /workspace/android/platform > cros-wm *$

indicating I am on cros-wm branch and there are modified files.

Git-goodness!
