SYNOPSIS /usr/sbin/rwall hostname
... /usr/sbin/rwall -n netgroup
... /usr/sbin/rwall -h hostname -n netgroup
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.
SEE ALSO attributes(7)
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.
