Keep Homebrew Tidy With `brew leaves`

Homebrew has a brew leaves command that shows all installed packages with no dependencies. That means that they can be uninstalled without causing issues to other installed Homebrew packages. It’s good to regularly run this command to keep Homebrew from getting too bloated.

Here’s what my brew leaves output looks like at the time of this writing:

$ brew leaves automake bat black coreutils ffmpeg go htop hugo jq libksba libpq libtool libyaml node openssl@1.1 pkg-config postgresql@14 python-typing-extensions tldr tree yt-dlp zlib 

In my case, I know I don’t need the libpq package anymore. So I can remove this package and then run brew leaves again to confirm it’s gone.

$ brew remove libpq Uninstalling /opt/homebrew/Cellar/libpq/16.1_1... (2,380 files, 29.9MB) 

$ brew leaves automake bat black coreutils ffmpeg go htop hugo jq libksba libtool libyaml node openssl@1.1 pkg-config postgresql@14 python-typing-extensions tldr tree yt-dlp zlib 

And now libpq is gone! Try out brew leaves yourself. You may be surprised at the amount of things installed that you may not actually need.
