SYNOPSIS

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

AVAILABILITY

SUNWcsu

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)

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.
