I am somewhat embarrassed to admit that this just occurred to me. Is the
reason that SIGKILL has the numeric value 9 because cats are reported to
have nine lives? Clearly the connection between 'cat' and 'kill -9' would
make for a irreverent but harmless inside joke if so....

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.

I think 9 has ties to "pain", but the number that has connection to
"death" in Japanese is 4 (四 shi, "four", which sounds like 死 shi,
"death").
-嘘.

Thanks, you're right, four. Psion 3 didn't use 4 for their next model,
that's what I was thinking of.

I wonder whether Plan9 used to be translated as plan-no, then.
Nine while nine (...waiting for the train).

I don’t agree the train was later,
"The one after nine oh nine” :-)

Isn't it nine = neun, but no = nein?
