Git Branch Name in terminal


Example

What is PS1

PS1 denotes Prompt String 1. It is the one of the prompt available in Linux/UNIX shell. When you open your terminal, it will display the content defined in PS1 variable in your bash prompt. In order to add branch name to bash prompt we have to edit the PS1 variable(set value of PS1 in ~/.bash_profile).

Display git branch name

Add following lines to your ~/.bash_profile

git_branch() {
 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\h \[\033[32m\]\w\[\033[33m\]\$(git_branch)\[\033[00m\] $ "

This git_branch function will find the branch name we are on. Once we are done with this changes we can nevigate to the git repo on the terminal and will be able to see the branch name.
