rwall(1M)							     rwall(1M)

NAME
       rwall - write to all users over a network

SYNOPSIS
       hostname ...

       netgroup ...

       host netgroup

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

       A machine can only receive such a message if it	is  running  which  is
       normally started from by the 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.
