I'm not "going off on your own, prefered syntax", I was just trying to
help you and us to reach a point where what you post would be readable and
understandable (On a technical point of view that is, I won't try and
do anything about your Tourette and the dried mushrooms).

So, the answer to that question:
" Why don't you comment on my obvious attempt to TRACE the <arg
...
"
is that I wouldn't comment something that was not obvious at all to
me as I really couldn't find a reason why you posted that snippet of
non code coming out from the blue and going nowhere.

That's the part of your initial post that was quite understandable, since
then you had several various answers, including a few about the ARGV stuff
and, though I thought theses answers addressed your question you then started
roaring like a Vulcan forcefed with powerpoint presentations.
So I supposed you still had a problem with your "search script" and I
simply asked if your question could be simplified and exampled on  a very
small set of bench stuff and hence proposed a first version of
bench that you would "admit" or "extend" or propose a better one.

The question until now, for me, is that you're requesting every one to
use some specific words in some sentences in order to write a paragraph
but I just suggested that we all start with being in tune about what the
final paragraph would express.

I'd say others already have done so, and as for myself I won't comment
about the style on an operation that I have no idea what its goal is.
You may have some reasons to insist on using a corkscrew to file this
nail but at this point I still don't understand what are all these
spoons for and where do they joint with the yellow turtle in the middle
of the rack.

No, first I didn't recognize that you were attempting that and then
I still have no idea about (see supra...)

No. Nor any idea where I would have found that hint, but I may have
missed it somewhere in the tons of strange snippets ;-)

well, do you realize that so is mine ? Or so could it?
It is called directly in a shell but a shell is a script is a rose
(to most extents at least, we'll avoid any extensive discussion on
environments at this point of the thread as it already is quite
painful enough to read)

So, from the tiny bench I proposed are we going somewhere?
Is that close enough to you problem? If not could you post a
bench that would be usable and understandable enough that would do
the stuff you want and then the group could concentrate to 
understand enough your question and your addressing so we'll
have a chance to try any complementary answer about style/args/whatever.
