Show git branch in terminal

When working with git, to avoid accidental commit to wrong branch, it will be better if terminal show the branch name you are currently in.

To display “git branch” in terminal, edit .bashrc

vi ~/.bashrc

Add following code to end of the file.

# Show git branch in command promt if git repo

show_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]$(show_git_branch)\$ '

You will need to restart terminal after making changes to ~/.bashrc file or run

source ~/.bashrc
