NAME
rwall - write to all users over a network
SYNOPSIS
/usr/sbin/rwall
hostname ...
/usr/sbin/rwall -n
netgroup ...
/usr/sbin/rwall -h
host -n netgroup
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.
