While looking at my Github news feed today, I spotted an app via one of Jeff Triplett’s stars. The app is Sloth by Sveinbjorn Thordarson, and it provides a GUI frontend for lsof
that can quickly show you which processes are interacting with various files, directories, IP sockets, or Unix sockets.
This is a really useful tool, and easy to install via Homebrew. Just run brew install --cask sloth
.
