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.
