        Yep; this is the simple kind of script I had in mind first but
        wasn't sure if/how it would work.  Your one-liner works 
        "as-advertized", but then as you note, the timestamp is
        changed!! (duh)...  So it does make more sense to put the list
        into a /tmp/<foo> file.  Save typing when I re-edit.

        thanks much, indeed,

        gary
