RWALL 8 "Nov 6, 2000"
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
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.

SEE ALSO

attributes (7), inetd (8), listen (8), pmadm (8), sacadm (8), wall (8)

NOTES

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.
