.SH NAME
\f4rwall\f1 \- write to all users over a network
.SH SYNOPSIS
\f4/usr/sbin/rwall\f1
\f2hostname\f1 .\|.\|.
.SH DESCRIPTION
.P
\f4rwall\f1
reads a message from standard input until
\s-1EOF\s0.
It then sends this message,
preceded by the line:
.IP
.ft 4
Broadcast Message .\|.\|.
.ft 1
.P
to all users logged in on the specified host machines.
.P
A machine can only receive such a message if it is running
\f4rwalld\f1(1M),
which may be started by
\f4inetd\f1(1M)
or
\f4listen\f1(1M).
.SH 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.
