     -n netgroup

          which are defined in netgroup(4).

DESCRIPTION
     rwall reads a message from standard input until end-of-file.
     It then sends this message, preceded by the line

     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.
