But 'kill -9' is three less characters than 'kill -KILL', not to mention
the letters 'kay', 'eye' and 'ell' are all right next to each other,
which combined with holding SHIFT makes it a bit of a finger twister to
type 'kill -KILL' as opposed to 'kill -9'.
And... when's the last time SIGKILL changed from a value of int 9?
Using the signal names is probably more 'correct' but 'kill -9' comes
from the same fine legacy that gives us the 'sync three times before
reboot', 'init 6' instead of shutdown and many other useful/useless
traditions.
Or to put it another way, old school hackers will look at a youngster
typing 'kill -KILL', say, "What's wrong with you, son?" and hit them
over the head with a LISP machine.
