I once entered 'sudo echo hi" or something similar on a large HPCC and received an email back from a sysadmin that just said "hello".

That's an amusing anecdote, though I find it bothersome the sysadmin failed to correctly implement the echo command

I find it bothersome that the "yes" command outputs "y" by default instead of "yes". False advertising! Since Unix loves short concise command names, why not just name it "y"?

There's the talk command on Unix. We used to do a 'who' to find out who're on the system and 'talk' to them.

That was such a mind blowing experience coming from a DOS background. It would split your terminal horizontally and you could see each other type in real time.

Before the days of SMS, and even before the days of instant messengers like ICQ and AIM, I taught the split-screen `talk` command to my girlfriend so we could chat while I was working. We've been married for 20 years now.

I remember that one of the financial banking software we were using had an internal chat that was basically using "write"(?) underneath to send messages to another users terminal (it was running on Sun Solaris I think).

Back when I was at university the x servers on our terminals were not secured, and other people could open output on your terminal. A favourite was a program that sent cockroaches scurrying around the screen whenever you moved a window.
