Want all of that disk space back? Run brew cleanup -s:

I understand why Homebrew keeps the previous versions around but when utilities are stable, it's really time to take back the bytes. My first run of brew cleanup -s recovered 640MB of disk space, which is peanuts relative to the size of modern hard drives, but it's space that I want back!

I got about 32.2GB back on my laptop, which out of a 250GB drive is a chunk of space worth having. That also might explain why my Time Machine backups were always much bigger than I was expecting. Thanks for the tip. One question: I didn’t include the “-s” parameter – what does that do?
