Uninstall Homebrew

uninstall_homebrew.sh

#!/bin/sh
# Just copy and paste the lines below (all at once, it won't work line by line!)
# MAKE SURE YOU ARE HAPPY WITH WHAT IT DOES FIRST! THERE IS NO WARRANTY!

function abort {
  echo "$1"
  exit 1
}

set -e

/usr/bin/which -s git || abort "brew install git first!"
test -d /usr/local/.git || abort "brew update first!"

cd `brew --prefix`
git checkout master
git ls-files -z | pbcopy
rm -rf Cellar
bin/brew prune
pbpaste | xargs -0 rm
rm -r Library/Homebrew Library/Aliases Library/Formula Library/Contributions 
test -d Library/LinkedKegs && rm -r Library/LinkedKegs
rmdir -p bin Library share/man/man1 2> /dev/null
rm -rf .git
rm -rf ~/Library/Caches/Homebrew
rm -rf ~/Library/Logs/Homebrew
rm -rf /Library/Caches/Homebrew

Also, do I need to remove the .git directory at /usr/local/ as well? Is .git only associated with HomeBrew?

I dot I remove a broken brew ?

hi guys:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

so easy!

thanks jacknagel , that worked for me

the post from self-creative worked for me. sorry to necro a dead thread but i felt that needed to be said.

Thanks self-creative!

Thanks self-creative! Home brew managed to delete a project with my .git when I tried to commit. It installed poorly and reading through this thread was daunting. Glad I read to the bottom.

Thanks, @self-creative! You saved my time a lot.

For me this command worked! 🍺
