rwall(1M)                                                         rwall(1M)

NAME
     rwall - write to all users over a network

SYNOPSIS
     /usr/sbin/rwall hostname ...

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.

     A machine can only receive such a message if it is running rwalld(1M),
     which may be started by inetd(1M) or listen(1M).

NOTES
     The timeout is fairly short to allow transmission 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.

SEE ALSO
     inetd(1M), listen(1M), pmadm(1M), rwalld(1M), sacadm(1M), wall(1M).
