| Globbing happens to command lines after parameter substitution.
But wouldn't that mean that the following...
echo 'echo '$2' | sed '"s/^/ / ; s/\$/ / ; s/ $1 / / ; s/^ // ; s/ \$//"
...which produces...
echo * | sed s/^/ / ; s/$/ / ; s/ . / / ; s/^ // ; s/ $//
..._should_ have shown '*' in its expanded version? This was my "bone" of
yesterday and remains so today (no amount of chewing seems to help <g>).

I like it!

That's similar to what I'm actually using (building flist rather than
tearing it down).

Right -- there are lots of ways to go about most things, I think. Although,
I ran some timed tests and using the "teardown" routine along with 'ls -a'
is a bit faster than the "build" routine (and your build is faster than my
build:).
Thanks again. Although I'm starting to "intuit" a lot of what you're
saying, it really helps to have someone explain it!
