Re^3: Recursive search for duplicate files

I have a question: Since %path_file is a hash why becomes an array here:

 push @{$path_file{$filename}}, $path;
[download]

Dereferencing the array @path_file or the hash %path_file

The hash's values are references to arrays. Since push expects an array, not an array ref, it needs to be dereferenced with the `@{ $array_ref }` syntax.	[reply] [d/l]
