macOS command-line tools you might not know about

`pbcopy` and `pbpaste` are one of my most-loved in the list.

Dealing with some minified json, switching to iTerm, doing `pbpaste | json_pp | pbcopy` and having a clean output is _so_ nice.

If I had a nickel for each `cat foo.json | jq | pbcopy`, I'd be a rich man :)

That's a useless use of cat. You can use `jq . foo.json | pbcopy` or `jq < foo.json | pbcopy`.
