It is sometimes very useful to know the git branch you are working on right from the command prompt. You can do this by editing the ~/.bashrc file.
This will show up a prompt which looks like this and fails gracefully when you are not on a git repo.
vagmi@deepthought:~/work/testproj[master]$ git checkout new_feature
Switched to branch "new_feature"
vagmi@deepthought:~/work/testproj[new_feature]$ cd ..
vagmi@deepthought:~/work$
This saves a lot of "git branch" when you are coding.
