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.

I don't remember when I learned about these, but they've been game changers, and everyone I've shared them with feels the same way. I use your use case often as well, though through `jq` because I'm more familiar with it, and sometimes wish to do transforms.
