SSH Snippets

Hello,

To avoid confusion, by SSH Command I mean a single command, and by SSH Snippets I mean a smaller set of commands with a single purpose.

For example, a simple bash script:

#!/bin/bash

sudo apt update 
sudo apt dist-upgrade -y
sudo apt upgrade -y
sudo apt autoremove -y
sudo apt clean
sudo apt autoclean
sudo do-release-upgrade
if [ -f /var/run/reboot-required ]; then
	sudo reboot
fi

QUESTION

What to use to execute this script, because SSH Command does not support multi-line commands (snippet), it simply ends the activity after the first command from the first line of the snippet?
