GIT branch name in terminal prompt

20 Feb 2018 tools | #git #shell #bash #terminal

When developing its nice to know on what GIT branch we are working on. Instead of typing git status every time to check branch name, let’s make prompt customization to render branch name for us.

INFO
This tutorial is for Linux, Debian family.

Branch name will be visible only when we are in directory under GIT version control.

Login as user then edit .bashrc file.

$ sudo su username
$ vim ~/.bashrc

At the end of the file copy and paste below snippet. Colors are customizable. I choose one which compose good with default Ubuntu terminal theme.

parse_git_branch() {
   git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$\[\033[33m\]\$(parse_git_branch)\[\033[00m\] "

Linux read configuration files in sequence so in case you want to change PS1 prompt, changes have to be made in .bashrc file. To make the changes visible reopen terminal, re-login or source .bashrc.

$ source ~/.bashrc
