Why should it stop - while true will stay true and thus loop forever. Which it does. It will hog CPU like mad, eventually run your 18:30h job in between...
Use Jotne's proposal and you're there.


P.S.: That START: ... GOTO START is a DOSism, I think. I guess it's unavailable in any *nix shell.

rc.news

RC.NEWS(8)						    InterNetNews Documentation							RC.NEWS(8)

NAME

       rc.news - Start or stop INN daemons

SYNOPSIS

       rc.news [start | stop]

DESCRIPTION

       rc.news can be used to start or stop innd and supporting programs.  It checks to make sure INN is not already running, handles cases of
       unclean shutdown, finishes up tasks which might have been interrupted by the preceding shutdown, e-mails certain boot-time warnings to
       newsmaster (as set in inn.conf), and is generally safer and easier than starting and stopping everything directly.  It needs to be run as
       the news user so that files in pathrun are created with the right ownership (though this is less important for "rc.news stop").

       Programs run and stopped by this script include:

       o   Always:  innd is started or stopped.

       o   If doinnwatch is true in inn.conf:  innwatch is started and stopped.

       o   If docnfsstat is true in inn.conf:  ovdb_init is run; ovdb_server and ovdb_monitor are stopped.

       o   If rc.news.local exists in pathbin:	rc.news.local is run with argument "start" or "stop" (to perform site-specific startup or shutdown
	   tasks).

OPTIONS

       "start"
	   If the first argument is "start", or no first argument is given, rc.news initiates INN startup.

       "stop"
	   If the first argument is "stop", rc.news initiates INN shutdown.  It is recommended to throttle the server first as described in
	   ctlinnd(8).

EXAMPLES

       To start INN and leave certain error messages going to the terminal:

	      su - news -c <pathbin in inn.conf>/rc.news

       To run INN at startup time from appropriate system boot scripts:

	      su - news -c <pathbin>/rc.news >/dev/console

       To stop INN (throttling first):

	      <pathbin>/ctlinnd throttle reason
	      su - news -c '<pathbin>/rc.news stop'

BUGS

       Running "rc.news start" as root is never the right thing to do, so we should at minimum check for this and error, or perhaps change
       effective user ID.

HISTORY

       // FIXME:  any attribution for rc.news itself?
