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,
