rwall(1Mtcp)
rwall --
write to all users over a network
Synopsis
/usr/sbin/rwall hostname . . .
Description
The rwall command reads a message from standard input until EOF.
It then sends this message, preceded by the line:
Broadcast Message ...
to all users logged in on the specified host machines.
Usage
A machine can only receive rwall messages
if it is running
rwalld(1Mtcp).
rwalld may be started by
inetd(1Mtcp)
or
listen(1M).
Note that the timeout is fairly short to allow transmission to
a large group of machines (some of which may be down)
in a reasonable amount of time.
Thus the message may not get through to a heavily loaded machine.
