Could you please tell me where I've gone wrong?
Without the `$' what you are doing is creating an empty file named fn and successively updating the metadata each time it loops.

With a `$' you are just updating the metadata of the file that the for loop iterates over.

What you need is a different location where that file can live without conflicting with others, or change to a different name.
