commands

I was thinking, I could type in 'sudo apt-get update;sudo apt-get upgrade'
but what would be a more efficient way?

sudo {apt-get {update; upgrade}}
sudo: {apt-get: command not found
upgrade}}: command not found

sudo apt-get {update; upgrade}
E: Invalid operation {update
upgrade}: command not found

sudo {apt-get {update, upgrade}}
sudo: {apt-get: command not found

sudo apt-get {update, upgrade}
E: Invalid operation {update,

This is interesting: when I typed in 'sudo {apt-get {update; upgrade}}' it
didn't give me an error for '{update'

So does anyone know what I'm talking about and how to do it?
