Another advice I was once given is to always ls SOME_EXPRESSION_OR_WILDCARD
before rm SOME_EXPRESSION_OR_WILDCARD. mv will at least not eliminate
anything (under most circumstance), so it's reversible. I once heard a story
where someone (Toby Inkster) rm -rf'd in/under the wrong directory. To make
matters worse, he was logged in as root at the time.

I really liked that last sentence. Restoration from backups and
reinstallation are for lusers (sic).

Best wishes,
