How to show git branch in terminal and change terminal colours

To show git branch in terminal you need to edit your .bash_profile file or create if you don’t have it. This file should be in your user’s root directory. Open it with any text editor. For example:

open -t ~/.bash_profile

Then add this code to the bottom of .bash_profile:

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

export PS1="\u ::\[\033[01;33m\] \W\[\033[00m\] -\[\033[00;32m\]\$(parse_git_branch)\[\033[00m\] $ "
    Where:

  • \u stands for your user name;
  • \W — shows your current folder;
  • \$(parse_git_branch) — displays your current git branch;
  • Parts of code like \[\033[00;32m\] are responsible for changing the colours in terminal.

Eventually now your terminal input will look like this:

username :: folder - (git branch) $

Here are some other terminal colour codes you can use:

    Regular colours:

  • \[\033[00;30m\] — Black
  • \[\033[00;31m\] — Red
  • \[\033[00;32m\] — Green
  • \[\033[00;33m\] — Yellow
  • \[\033[00;34m\] — Blue
  • \[\033[00;35m\] — Purple
  • \[\033[00;36m\] — Cyan
  • \[\033[00;37m\] — White
    High intensity:

  • \[\033[00;90m\] — Black
  • \[\033[00;91m\] — Red
  • \[\033[00;92m\] — Green
  • \[\033[00;93m\] — Yellow
  • \[\033[00;94m\] — Blue
  • \[\033[00;95m\] — Purple
  • \[\033[00;96m\] — Cyan
  • \[\033[00;97m\] — White
    Background:

  • \[\033[40m\] — Black
  • \[\033[41m\] — Red
  • \[\033[42m\] — Green
  • \[\033[43m\] — Yellow
  • \[\033[44m\] — Blue
  • \[\033[45m\] — Purple
  • \[\033[46m\] — Cyan
  • \[\033[47m\] — White
    Backgrounds with high intensity:

  • \[\033[00;100m\] — Black
  • \[\033[00;101m\] — Red
  • \[\033[00;102m\] — Green
  • \[\033[00;103m\] — Yellow
  • \[\033[00;104m\] — Blue
  • \[\033[10;95m\] — Purple
  • \[\033[00;106m\] — Cyan
  • \[\033[00;107m\] — White

You can replace any leading second 0; with 1; for bold colours and replace any leading second 0; with 4; to get text underlined.

Note that if you already have PS1 variable, then you’ll just need to modify it by adding this code to the end of PS1:

-\[\033[00;32m\]\$(parse_git_branch)\[\033[00m\] $
