Git Aware Bash Prompt
Raw
git-aware-bash-prompt.md

In Terminal

mkdir ~/.bash

Copy the raw git-prompt.sh file from git contrib in to the ~/.bash directory: https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh

Inside ~/.bashrc or ~/.bash_profile (choose the file where you normally put any bash customizations/setup), add the lines:

source ~/.bash/git-prompt.sh # Show git branch name at command prompt
export GIT_PS1_SHOWCOLORHINTS=true # Option for git-prompt.sh to show branch name in color

# Terminal Prompt:
# Include git branch, use PROMPT_COMMAND (not PS1) to get color output (see git-prompt.sh for more)
export PROMPT_COMMAND='__git_ps1 "\w" "\n\\\$ "' # Git branch (relies on git-prompt.sh)

As long as you're inside a git repo, your Bash prompt should now show the current git branch in color signifying if its got uncommitted changes.
