How about something _like_ the above (spur of the moment idea,
written in 'bash'...

Interactively, you type 'move' or 'remove'
(or whatever you want to name them). But scripts you run
 won't be affected.

Might have to adjust for your use case, but might protect against
most cases.

Nightly backups also help prevent catastrophic problems.

At the same time, with functions or aliases, you could test for
the existence of the arguments before actually executing them.
