NAME
       rwall - write to all users over a network

SYNOPSIS
       rwall hostname ...
       rwall -n netgroup ...
       rwall -h host -n netgroup

DESCRIPTION
       Rwall  reads  a message from standard input until end-of-file.  It then
       sends this message, preceded by the line ``Broadcast Message ...'',  to
       all  users  logged  in  on  the	specified  host machines.  With the -n
       option, it sends to the specified network groups, which are defined  in
       netgroup(5).

       A  machine  can only receive such a message if it is running rwalld(8),
       which is normally started up by the daemon inetd(8).

SEE ALSO
       wall(1), netgroup(5), rwalld(8C), shutdown(8)

BUGS
       The timeout is fairly short in order to be able	to  send  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.
