rwall(1M)                                               rwall(1M)



     NAME
          rwall - write to all users over a network

     SYNOPSIS
          rwall host1 host2 ...
          rwall -n netgroup1 netgroup2 ...
          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.

          A machine can receive such a message only if it is running
          the Internet daemon, inetd(1M), which will invoke rwalld if
          /usr/etc/rpc.rwalld is listed in the file /etc/servers.

     FLAG OPTIONS
          The following flag options are interpreted by rwall:

          -n   Send the message to the specified network groups, which
               are defined in netgroup(4).

          -h   Specify host for netgroup.  If this option is used, it
               must precede the -n option.

     FILES
          /usr/etc/rwall
          /etc/servers
