Want to know which Homebrew casks can replace software already
installed to your
/Applications/ folder? Run this script to
automatically check for Homebrew alternatives. Might not catch 100% of
the Applications, but will give you a good start if you are looking to
use Homebrew for more of the software you have installed.
Install with Homebrew:
brew install jakevossen5/taps/check-for-homebrew-alternatives
check-for-homebrew-alternatives. It has to make an API
request to every cask, so it will take a while. Be paitent.
