rwall(1)							     rwall(1)



NAME

  rwall	- Write	to all users over a network

SYNOPSIS

  /usr/sbin/rwall hostname...

  /usr/sbin/rwall -n  netgroup...

  /usr/sbin/rwall -h hostname -n netgroup

OPTIONS

  -n netgroup
      Send the broadcast message to the	specified network groups.

  -h hostname
      Specify the hostname, the	name of	the host.

DESCRIPTION

  The rwall command reads a message from standard input	until end-of-file. It
  then sends the following message to all users	logged in on the specified
  host machines, preceded by the line:

       Broadcast Message ...


  With the -n option, it sends to the specified	network	groups.

  Note,	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.

  A remote host	only responds if it is running the rwalld daemon, which	is
  normally started up from inetd(8).
