rwall(1)						      General Commands Manual							  rwall(1)

NAME
       rwall - Write to all users over a network

SYNOPSIS
       /usr/sbin/rwall hostname...

       /usr/sbin/rwall -n  netgroup...

       /usr/sbin/rwall -h hostname -n netgroup

OPTIONS
       Send the broadcast message to the specified network groups.  Specify the hostname, the name of the host.

DESCRIPTION
       The  rwall command reads a message from standard input until end-of-file. It then sends the following message to all users logged in on the
       specified host machines, preceded by the line:

       Broadcast Message ...

       With the -n option, it sends to the specified network groups.

       Note, 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.

       A remote host only responds if it is running the rwalld daemon, which is normally started up from inetd(8).
