RWALL(8) | Maintenance Commands and Procedures | RWALL(8) |
rwall - write to all users over a network
/usr/sbin/rwall hostname...
/usr/sbin/rwall -n netgroup...
/usr/sbin/rwall -h hostname -n netgroup
rwall reads a message from standard input until EOF. It then sends this message, preceded by the line:
to all users logged in on the specified host machines. With the -n option, it sends to the specified network groups.
-n netgroup
-h hostname
attributes(7), inetd(8), listen(8), pmadm(8), sacadm(8), wall(8)
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.
