Manual page for RWALL(1C)
rwall - write to all users over a network
SYNOPSIS
rwall
hostname ...
rwall
-n
netgroup ...
rwall
-h
host
-n
netgroup
DESCRIPTION
Rwall
reads a message from standard input until end-of-file.
It then sends this message,
preceded by the line ``Broadcast Message ...'',
to all users logged in on the specified host machines.
With the
-n
option,
it sends to the specified network groups,
which are defined in
netgroup.5
A machine can only receive such a message if it is running
rwalld.8
which is normally started up
by the daemon
inetd.8
SEE ALSO
wall(1), netgroup(5), rwalld(8C), shutdown(8)
BUGS
The timeout is fairly short in order to be able to send 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.
