@ids1024 For the longest time I exited vi by ctrl z followed by "killall -9 vi", seeing as if any vi processes were running as my user anywhere it'd definitely not be intentionally, so might as well brutally murder them all.
I did eventually learn esc + :q! as I certainly wouldn't want to write back whatever I'd mangled the buffer with to disk.
Then there was that time I symlinked vi to emacs on the shell server of the ISP I ran (muhahaha... the cries of the vi users; I did revert it)
