I often find myself with so many leftover packages in Homebrew from a project that it is easy for conflicts to happen. As a result I need a way to quickly clear out all the packages I have installed so I can quickly re-install only what I need. Homebrew doesn’t have a built-in way to do so but it isn’t hard to get around. Here’s a quick one-liner that will delete every package you’ve installed with Homebrew.

brew remove --force $(brew list --formula) --ignore-dependencies
