This morning early. I typed ed instead of cd. As you can see like a noob I panicked until, well, eventually. I realize it was ed. 
Oops!
Anyone else have a terminal moment like this? Wrong command, wrong server, wrong directory, stuck in vim, a rm -rf that made your heart stop… Share your best (or worst) brain.exe-stopped-responding story below. Bonus points if it happened in production.
My previous, typo was a far worse outcome, I belive it was last year I typed crontab -r instead of e. 
crontab -r deletes your entire crontab immediately, no confirmation! 
e and r are keyboard neighbors so it’s not that hard to hit the wrong one. It took me about an hour to extra a backup of cron jobs from a nightly snapshot.
