macOS command-line tools you might not know about

pbcopy/pbpaste are a lifesaver when doing stuff on the command line that has a lot of output and piping is not something you can do.

networkQuality is something I really wish I knew about sooner.

Also for things like sharing public ssh keys. Instead of "can you send me your public key" and getting something with random line breaks depending on the users text editor I just have to ask them to "cat ~/.ssh/id_rsa.pub | pbcopy".

I also alias pbcopy / pbpaste on Linux too, so useful!

The random linebreaks are ok - SSH can handle them. (that's how Userify does it I think, too. it replicates whatever the user provides.. no judgment :)

Ah, it's more for ~/.ssh/authorized_keys which is one key per line.
