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

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.
