Re: matches=0 still triggers action

[David E. Nelson]

Hi Sven,

Ok, I read over the section - I understand now.

I still don't have a clear idea of how to stop 'lpsched' since /etc/init.d/lp 
uses 'lpshut' rather than signalling 'lpsched' to die.  Since the OS designers 
specifically use 'lpshut' (and it's not a script that simply kills either) to 
stop 'lpsched' and its friends (if any), I'd rather use that method rather than 
kill. Ideas?

Thanks,
         /\/elson
