Pardon me for "jumping the gun" so to speak -- I replied directly to Ralph
late last night. My aplogies to Ralph and others if I shouldn't have done
that.

Anyway -- here's my current status on this

I appreciate the reply, but don't understand what you are trying to tell me.
I got out my cURL docs (the ones I chased down and printed off the web a
year or so ago).

I do not understand your combination of options. -o writes the data cURL
retrieves into a file (I have used this in other cURL scripts and then
manipulate the data via PHP).

I also think I understand -L -- it is supposed to instruct cURL to go to the
new page, right? But in my case it doesn't seem to be following to the page
I want.

I do not understand -w -- what is it actually doing? It seems to be in
direct conflict with -o

It's been a while since I've used UNIX (used to be a systems
administrator -- these days I run Windows NT servers). I remember that the
grave accents cause the shell to execute what's in them -- the cURL command
here -- but just what is being stored in EFFURL? I mean... if you use the -o
parameter why do you need EFFRUL -- isn't the output already stored in
"file.html"?

Thanks.
