wall

Before there was instant messenger, there was wall and talk. The unix command wall sends a broadcast message to terminals. The message may be in a file, or the message may be typed interactively.

For interactive use type wall, then the message, then press ctrl-d.


Example on HP-UX:
testuser@host $ wall
Testing 1 2 3 ...
PRESS CTRL-d HERE

Broadcast Message from testuser (pts/0) Mon Jun 12 15:41:54...
Testing 1 2 3 ...
