In-Reply-To: References: Message-ID: <20171114200751.3536621358@orac.inputplus.co.uk> Hi Dan, > Is the reason that SIGKILL has the numeric value 9 If you look at signals 1 to 8 they could all be caught, etc. 9 was added so to thwart this and just took the next number AFAIK. Doesn't 9 have tie-ins to "death" in Japan? ISTR some marketing avoiding it in version numbers. -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
