!(-d $name)
[download]

should be

-f $name
[download]

After all, there's plenty of things a directory entry can be besides a plain file and a directory.

You should probably also consider whether the name test shouldn't instead be

 $file !~ /^\./
[download]

because, theoretically, any file whose name begins with dot is supposed to be "hidden". Of course, you may in fact want to search the hidden files as well; I don't know.
