But you have to run apt-get update first, AS root. (Your subject line includes the phrase "as a non-root user", but you neglected to include this important piece of information in the body of the email. I say this now, because someone might change the subject header later.) A script that only tells you whether you neglected to do an upgrade after your last update isn't all that useful, at least to me. I very rarely forget to follow up the update with an upgrade.
