I wrote something and was wondering if I could shorten it. I wrote:

sudo adduser pi audio
sudo adduser pi video
sudo adduser pi input
sudo adduser pi dialout
sudo adduser pi plugdev
sudo adduser pi tty

And was thinking I could shorten it to:

sudo adduser pi{ audio video input dialout plugdev tty}

Would that work? If not how should I do it?
