Why skip potential error messages?

Because oldest_bak can be empty and this causing mv to spit an error - which is OK as we are only interested in the return code telling us if the move was successful. In this case the failed move is expected. No need for an error message.

If we want to match 0, we should do -eq 0, otherwise the documentation will need to be adjusted.

Fine with me, usually errors are positive integers and I learned never ever to match numbers with "eq" - but for integers here it might be ok, so feel free to use -eq.
