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.
