Answer by Shayan Amani for How to get the current branch name in Git?

Simply, add following lines to your ~/.bash_profile:

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

In this way, you can have the current branch name in Terminal
