RWALL(1C)                                                            RWALL(1C)



NAME
       rwall - write to all users over a network

SYNOPSIS
       /usr/etc/rwall hostname...
       /usr/etc/rwall -n netgroup...
       /usr/etc/rwall -h hostname -n netgroup

AVAILABILITY
       This  command  is  available  with the Networking software installation
       option.  Refer to for information on how to install optional software.

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.  With the -n option, it
       sends  to  the  specified  network  groups,  which  are defined in net-
       group(5).

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

FILES
       /etc/inetd.conf

SEE ALSO
       wall(1), netgroup(5), inetd(8C), 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.
