You can effortlessly show your current git branch in your terminal without having to run git branch every time. The terminal can easily be customized beyond just showing your current git branch but in this article, I would focus on only showing you how to display your current git branch.

TLDR

Copy and paste this code to the bottom of your ~/bash_profile file.

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

PS1_date="\[\033[38;5;237m\]\d\[$(tput sgr0)\]\[\033[38;5;15m\]"
PS1_time="\[$(tput sgr0)\]\[\033[38;5;236m\]\t\[$(tput sgr0)\]\[\033[38;5;15m\]"
PS1_wdir="\[$(tput sgr0)\]\[\033[38;5;24m\]\W"
PS1_gitbranch="\e[38;5;204m\]\$(parse_git_branch)"
PS1_gt="\[$(tput bold)\]\[$(tput sgr0)\]\[\e[38;5;214m\]>"
PS1_other="\[$(tput sgr0)\]\[$(tput sgr0)\]\[\e[38;5;15m\]"

export PS1="${PS1_date} ${PS1_time} ${PS1_wdir}${PS1_gitbranch}${PS1_gt}${PS1_other} \[$(tput sgr0)\]"

That's it! Now open a new terminal tab to see the effect.

Customize the text, color, and appearance.

\u stands for your user name;
\W – shows your current folder;
Each variable defined has a similar code that looks like this [\033[01;33m\] , this is the section you might want to play with.

The number before the semicolon ; determines the styling/appearance of the text; 00 for normal, 01 for bold and 04 for underline.

The number after the semicolon ; determines the color of the text; 30m for black, 31m for red, 32m for green, etc.

If you want to use other colors, check the codes below

\[\033[00;30m\] – Black
\[\033[00;31m\] – Red

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)\[\033[00m\] $
