The perils of `rm -rf`
I came across this question on Stack Exchange about how to recover from an accidental rm -rf /*.
The questioner says he runs a small web-hosting service, and accidentally deleted all the files on his servers, and all the files on his backup drives. He asks how to recover. (The answer: it’s difficult.)
This made me smile, because I, like everyone who programs for a living, have an rm -rf story too.
