It was largely too broad
your previous "on topic" question example was specific. How to download using a specific program (wget).

Your question effectively asked us to try rubbing every possible downloading software against it in the hopes that someone finds a solution.
If you'd said "I tried x and then tried scripting it and almost got what I want but not quite" then we could at least look at how far you'd gone and work onwards. That would be something specific we could work with.
