At uni I used to keep a text file with huge ascii art one word messages (redundant but large) and I'd "write myfriend lunch.txt" or whatever and they'd get a huge "lunch?" on their terminal. It was even more disruptive than texting is today ;-)

In addition to 'wall' you can write to another user's tty if you're logged into the same machine with 'write'

And if their perms permissions are wrong on their tty, you can /usr/games/rain > /dev/tty24 or whatever. That was great fun back when.

Try c-hey! It's skinnable write :)

That's awesome! Thanks for pointing it out.

Largely `wall`. As of a few days ago there's an IRC server running on localhost.
