NAME

rwall − write to all users over a network

SYNOPSIS

/usr/sbin/rwall hostname . . . 

DESCRIPTION

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. 

A machine can only receive such a message if it is running rwalld(1M), which may be started by inetd(1M) or listen(1M). 

NOTES

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.
