This code:

push(@{$matchedfiles[$c]}, [ ... ]); Is incorrect, it's usually a bad idea to use the index from one array to index into another array. $c holds the position in your fileinfo array but $matchedfiles[$c] is not defined yet. The error is compounded when you use $matchedfiles[$c] as an array reference as perl will automatically cause that element to spring to life ( and everything below it ) even if that element was not previously defined. This is called 'autovivification' and can be useful; but in this case is merely a troublesome side-effect of using an undefined reference.
