Yes, I believe we have, but this time I understood the replies better,
well enough to fix my warnings to the point that it is no longer needing
to have its shell output sent to >/dev/null 2>&1 &. That means I can
fine tune it and adjust it with no more effort than a ctl+c and a rerun
to check my changes. That is a huge improvement right there, which is
why I tendered thank you's to all who participated, and still do.
For the nonce, I believe this thread is cooked to perfection (until
someone moves perfection, and I believe I've seen a Murphy's Law
corollary on that subject, someplace in the last 75 years), so thanks
again everybody, including you David.
