rwall(1M)

DESCRIPTION

rwall reads a message from standard input until EOF, then sends the message, preceded by the line Broadcast Message ..., to all users logged in on the specified host machines. With the -n option, rwall sends the message to the specified network hosts defined in /etc/netgroup (see netgroup(4)).

A machine can only receive such a message if it is running rwalld, which is normally started from /etc/inetd.conf by the inetd daemon (see inetd(1M)).

WARNINGS

The timeout is kept fairly short so that the message can be sent 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.
