Display git branch in bash prompt

.bashrc

# If you work with git, you've probably had that nagging sensation of not knowing what branch you are on. Worry no longer!

export PS1="\\w:\$(git branch 2>/dev/null | grep '^*' | colrm 1 2)\$ "

# This will change your prompt to display not only your working directory but also your current git branch, if you have one. Pretty nifty!

# ~/code/web:beta_directory$ git checkout master
# Switched to branch "master"
# ~/code/web:master$ git checkout beta_directory
# Switched to branch "beta_directory"
# ~/code/web:beta_directory$ 

PS1="\[\e[0;1;34m\]\W \[\e[0;1;33m\]\$(git branch 2>/dev/null | grep '^*' | colrm 1 2)\[\e[0;7;0;37m\]$ "

Try this, for minimal text on terminal, with present working directory in blue and branch in yellow color

[...] git branch 2>/dev/null | grep '^*' | colrm 1 2 [...]

Or with a newer Git:

git branch --show-current 2>/dev/null

It's not shorter, but easier to understand ;-)

git branch --show-current 2>/dev/null

Is not working with newer git

This has been supported since at least Git 2.28.0, but let us not spend any more time on this. Your solution works for all versions :-)
