I don't understand the above commands fully, for example the esac and color
parts. Should esac not be preceded by case somewhere?

But want to put the process into a script so it can be executed simply by
calling the script with sudo.

After seeing the Bret Busby post I started writing this, will that work or do I
have to handle other stuff as well:

----
#!/bin/bash
# This script will do a full system update-upgrade-clean process
# It must be called using sudo with argument Y

if [ "$1" != "Y" ]; then
  echo "Error! Call syntax: sudo $0 Y"
  echo "Try again!"
  exit -1
fi

apt update
if [ $? != "0" ]; then
  echo "Unable to run apt update command! Exiting..."
  exit 1
fi

apt full-upgrade -y
if [ $? != "0" ]; then
  echo "Unable to run apt full-upgrade -y command! Exiting..."
  exit 2
fi

apt autoremove
if [ $? != "0" ]; then
  echo "Unable to run apt autoremove command! Exiting..."
  exit 3
fi

apt autoclean
if [ $? != "0" ]; then
  echo "Unable to run apt autoclean command! Exiting..."
  exit 4
fi

echo "System updated/upgraded successfully"
exit 0

Grateful for comments!
