The only "normative" standard that would seem meaningful would be
POSIX. A quick "google" doesn't find anything relevant there.
The most relevant thing is pointers to the GNU utilities, which is
where the "kill" used on Linux comes from. The man page for that
indicates TERM as the default, and later has pointers to POSIX.1 as
its 'source of authority.'
I'd hazard the guess that perhaps that default was declared in POSIX,
which is at least a form of standard. It may not be normative for
BSD, but it is still instructive...
Have you ever had a "bad day" when you issued "kill -3" rather than
"kill 2"? I have also had the day when part of me wanted "kill it
now; kill -3", another part knew "No, you should just use kill -2, and
wait...", and my treacherous fingers wound up taking the wrong side in
the conflict ;-).
Rules of the Evil Overlord #144. "I will order my guards to stand in a
line when they shoot at the hero so he cannot duck and have them
accidentally shoot each other. Also, I will order some to aim above,
below, and to the sides so he cannot jump out of the way."
