Creating UUID under Mac OS Shell

I have the following alias in my .bashrc to create UUID’s quickly from the shell:

alias uuid="uuidgen | tr -d - | tr -d '\n' | tr '[:upper:]' '[:lower:]' | pbcopy && pbpaste && echo"
This generates a lowercase uuid and copies it to the clipboard all by calling uuid.
