Updating UUID Generation on macOS Monterey
With the update to macOS Monterey, the previous macOS command-line program for generating UUIDs, uuid, has been replaced with uuidgen. I'm not at all sure why the change, but I was glad that a little investigation with ls /usr/bin revealed something that turned out to be the winner.
With this, one of my favorite aliases is now:
alias uupb="uuidgen | tr '[:upper:]' '[:lower:]' | tr -d '\n' | pbcopy"
which generates a new UUID, lower-cases all the characters, removes the trailing new-line, and then puts it into the paste buffer for pasting in an editor, or on a form... as many times as you need.
I don't know if there are even release notes about the changes at this level of macOS, but they usually get figured out - one way or another. 🙂
