      Match a filename how?

      1. This won't compile as you haven't declared %Hash_filenames and you're using
      "strict" and "warnings". Did you actually try running the program?

      2. You should initialise %hash_filenames (please don't use uppercase letter
      unnecessarily) using either "()" (or nothing at all as a hash is empty by
      default) - not "{}" which is the anonymous hash-ref constructor.

      > $file name = "Data";

      Again this won't compile - 1) You don't have a "my". 2) whitespaces are not
      recognised by Perl as part of the variable name (unless you do some ugly
      tricks with package-scope variables).

      There are more problems like that below. Please fix all the compilation
      problems and return to us. See http://perl-begin.org/ for more guidance about
