Gentelmen never tell.

Ok enough of that.  No, I just was being lazy actually.  I was in a
hurry trying to make the thing work so I skipped the commenting n that
stuff.  Shame on me I know.

>How is this script executed?
I have a script for each section that I manually run at this point.  I
would like to eventually have a master script that fires each of the
other off in sequence.  As of now though I just manually run each of
them.

>how is it logged?
It wasnt.  Again shame on me.

>In the future, showing the full output..
Ok here is the updated script.  With some additional help I was able
to identify the part that didnt work from the previous script due to
line continuation of the "echo".  It worked fine when manually typed,
but not in a script due to missing "\" or breaking it into multiple
"echo"s like I did.
