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 :)
networkQuality is something I really wish I knew about sooner.
