rwall 1M "6 Nov 2000" "SunOS 5.11" "System Administration Commands"
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

inetd(1M), listen(1M), pmadm(1M), sacadm(1M), wall(1M), attributes(5)

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.
