Mole Cleaner

I've been a regular user of Clean My Mac for many years. I can't tell you the number of times I've filled my hard drive and CleanMyMac has been able to find and purge many gigs of unnecessary data. It's great!

I recently became aware of Mole - a command line tool that cleans to do much the same thing. In fact, it says it's a "All-in-one toolkit: CleanMyMac, AppCleaner, DaisyDisk, and iStat Menus combined into a single binary" Ok!

Both are good options but Mole is free and feels powerfully nerdy running it from the CLI.
