In the spirit of <snip> hosting problems....
Fess up. You've done them. Screwed up the server.
Me:
1) rm -Rf * < enter >. Which is what I wanted, except I was up 2 directories in my main directory.
Of course I do have offsite nightly backups (unlike <snip> apparently :) ) so I just copied last night's files back up again. Live in under 5 minutes.
I bet you've done that too. Nowadays I check the directory I'm in first. Every time.
2) My personal fave. from a terminal on my desktop I issued the command 'shutdown -h now' to shut down my desktop. Except the terminal window wasn't logged on to my desktop, it was a terminal window to my main webserver. D'Oh!
I forget how I fixed that one, probably a call to my host to cycle the power. No idea why I would shut down my desktop, and if I did, why I would do it that way.
