Yes, agreed, why not simply run the individual commands at the prompt,
and avoid all those sudo prefixes (see below).

I simply do:-

    sudo -i

followed by (at the root prompt):-

    apt update
    apt upgrade
    apt autoremove
    apt clean

I only do the 'apt clean' occasionally, it clears out the apt cache
which can clear quite a bit of space.  An alternative is 'apt
autoclean', look at the apt-get man page to see exactly what they do
(it does what that 'mv' command does basically).
