Several years ago I remember reading on stack overflow about how someone had managed to rm the ls program on a Linux system. Your anecdote reminded me of the fix. I’ll do some googling and see if I can find it. If I can, I’ll post it here.

Hats off to people like you. You’re what we mere mortals aspire to, and it’s always encouraging to hear that someone else has attained a level of mastery. Makes it seem more achievable!
