This command is available with the Networking software installation option. Refer to [a manual with the abbreviation INSTALL] for information on how to install optional software.
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, which are defined in netgroup.5
A machine can only receive such a message if it is running rwalld.8c which is normally started up from /etc/inetd.conf by the daemon inetd.8c
The timeout is fairly short in order to be able to send 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.
