Of course, rss downloader can't understand a shell language, in this case bash syntax.
But, let me reframe what you've said and tell me if that's what you want or not .
You want to download new files with rss downloader to new folders each day.
So Today's files will go to 7262017 directory.
Tomorrow's files will go to 7272017 directory.
and so on ...
Is that What you want?
