in thread 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.
