rwall(1M) UNIX System V rwall(1M)
NAME
rwall - write to all users over a network
SYNOPSIS
/usr/sbin/rwall hostname . . .
DESCRIPTION
rwall 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.
A machine can only receive such a message if it is running rwalld(1M),
which may be started by inetd(1M) or listen(1M).
NOTES
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.
