      NAME
           wall - write to all users

      SYNOPSIS
           wall

      DESCRIPTION
           Wall reads its standard input until an end-of-file.  It  then  sends
           this  message, preceded by `Broadcast Message ...', to all logged in
           users.

           The sender should be super-user  to  override  any  protections  the
           users may have invoked.

      FILES
           /dev/tty?
           /etc/utmp

      SEE ALSO
           mesg(1), write(1)

      DIAGNOSTICS
           `Cannot send to ...' when the open on a user's tty file fails.
