Git provides a series of enhancements for the bash prompt. It can display the current branch when inside a working copy. Here's an example from my machine:
{syntaxhighlighter brush: bash; gutter: false}
stefan@debian:~/Documents/Projects/Drupal/test(master *)$
{/syntaxhighlighter}
It shows the branch name and indicates by an asterisk that I have uncommitted changes.
