SYNOPSIS

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

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

OPTIONS

-n netgroup Send the broadcast message to the specified network groups. -h hostname Specify the hostname, the name of the host machine.

NOTES

The timeout is fairly short to allow transmission to a large group of machines (some of which may be down) in a reason- able amount of time. Thus the message may not get through to a heavily loaded machine. SunOS 5.8 Last change: 14 Sep 1992 1
