How to Add Your Current Git Branch to Your Terminal Prompt in Unix/Mac OSX?

1. Download the git-prompt.sh file from github using the curl command in the terminal window.
~ ? curl -Lo .git-prompt.sh https://raw.githubusercontent.com/git/git/master/contrib/completion/git-prompt.sh           

2. Add the following to your .bash_profile or .bashrc file:

if [ -f ~/.git-prompt.sh ]; then                                                                                            

   source ~/.git-prompt.sh                                                                                                  

   export PS1='\W\e[1;32m$(__git_ps1 "(%s)")\e[m\$ '                                                            

fi                                                                                                                                       

This small script adds an if statement to check if the file exists, sets the source to .git-prompt.sh, and set the PS1 variable to point to the __git_ps1 function in the .git-prompt.sh file.  The \e[1;32m and \e[m\ are color tags used to color the branch text.  

When you navigate to a folder that contains a git repository you should see something like the following:
GitProjectFolder (Master) $ git checkout NewBranch                                                           

GitProjectFolder (NewBranch) $

Customizing the Color of Your Terminal Prompt

I posted a quick tip a couple of weeks ago about on how to Change the Terminal Command Prompt.

I want to take it one step further and add custom color to the prompt and/or to a portion of the prompt.

 currentDirectory$   export PS1='\e[1;32m\W\e[m\$'                                                   

 currentDirectory$                                                                                                    

I found this link to be a good bash prompt overview of how to customize your terminal prompt and has a list of fore and background colors show below:

Foreground colors, Normal (non-bold) is the default, so the 0; prefix is optional.

\e[0;30m = Dark Gray
\e[1;30m = Bold Dark Gray
\e[0;31m = Red
\e[1;31m = Bold Red
\e[0;32m = Green
\e[1;32m = Bold Green
\e[0;33m = Yellow
\e[1;33m = Bold Yellow
\e[0;34m = Blue
\e[1;34m = Bold Blue
\e[0;35m = Purple
\e[1;35m = Bold Purple
\e[0;36m = Turquoise
\e[1;36m = Bold Turquoise
\e[0;37m = Light Gray
\e[1;37m = Bold Light Gray

Background colors:

\e[40m = Dark Gray
\e[41m = Red
\e[42m = Green
\e[43m = Yellow
\e[44m = Blue
