I remember trying to help a fellow student in Manchester University around 1991 and thinking I was deleting a subfolder when in fact I was in their home directory:

rm -rf *

: and deleting everything from their Sun Workstation Unix account. Apologies!

I went to clear some games off a drive to make room for new games, went to type RM -rf ./ and accidentally smacked enter instead of a slash. Wiped out a few games before I could stop it.

Got lucky there was nothing really important on there, and it didn't take long to fix things up. Fortunately, some stuff I was removing was at the top anyway.
