For several servers I maintain we took the bash code and hacked it to
log all commands, with usernames, to a log file. Yes, it's nosy. It's
actually called 'nosy bash' by us. It's not been sent to the bash
maintainers at all yet, but I could see if my coder can make a diff of

"I didn't do that!"
"Well, yes, you did. At 1:43:00 you type 'rm -rf /' "
"No I didn't"
"Yes, see, it's in the logs."
I regualrly grep the log for keywords or sometimes tail it if I'm
suspicious of someone. But for the most part, I don't ogle it
constantly. Who has time for that?
I'm also running grsec patches as well. Grsec didn't do the nosy bash
like I wanted, so I'm keepign the nosy bash.
