RWALL(1M) Maintenance Commands RWALL(1M)


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.
