RWALL(8) Maintenance Commands and Procedures RWALL(8)

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.
