Hi Kees, Wanted to let you know that I've now got this working. I had never scripted in Linux before, but I set up your examples, then played with the exclusion syntax (to find it is indeed regex) while watching the results. Even as I ran the tests the duration kept getting smaller and smaller.
I think the way I'll strategize about this is to create several aliases for the most common scans I anticipate doing, with appropriate command line inclusions in each one (one folder has a bunch of Windows stuff in it). In any case, this is what I was looking for, and I thank you again for taking the time to get me started up. Much appreciated!
