It's safe to say that today, most people using Debian-based systems are using the shortened commands:

apt update - replaces apt-get update

apt upgrade - replaces apt-get upgrade

and to chain them together, you get something like this on Debian:
apt update && apt upgrade -y && apt autoclean -y

For Ubuntu based distributions that have sudo pre-installed and rely on snaps
sudo apt update && sudo apt ugprade -y && sudo apt autoclean -y && sudo snap refresh

This command, on an Ubuntu system will update repositories, upgrade packages, clean old packages and update snaps.
