thanks for that, yes find has to be
if the search has to be recursive,
because, some incoming downloads come with sub folders and sub-folders etc, its better to just search the entire directory tree and get the files i want. after that i can deal with the garbage.
I'm currently fighting with crontab -e, everything looks fine, the sh script gets executed but, none of the processing takes effect, so I'm currently looking into permission problem or something else.
