handy Mac cmd

I use a mac for video and photos. I’ve never done much else on one, but I found Homebrew — The Missing Package Manager for macOS (or Linux) which is great for someone like me who does most of their other work on a ‘nix machine and loves using the command line (read as ‘old dude’). This command specially. Afforded me more disk space. ‘$ brew update && brew upgrade && brew cleanup’
