Hello Christoforo,

Thanks for your time and effort to reply to my question. Well unfortunately this is not exactly what I want to do. My current solution is exactly what I want.

Sample of output using 2 dimension arrays:

$VAR1 = [
          [
            'Line_1_3',
            'Line_2_3'
          ],
          [
            'Line_3_3'
          ],
          [
            'Line_4_3',
            'Line_5_3',
            'Line_6_3',
            'Line_7_3'
          ]
        ];

Sample of array with hashes:

$VAR1 = {
          'sample.txt' => [
                            'Line_1_3',
                            'Line_2_3'
                          ],
          'sample_2.txt' => [
                              'Line_3_3'
                            ],
          'sample_3.txt' => [
                              'Line_4_3',
                              'Line_5_3',
                              'Line_6_3',
                              'Line_7_3'
                            ]
        };

The reason is that possibly the files are not the same in line (size) etc. etc. I am trying to retrieve the arrays one by one so I can play around with it.

I have found a way to print all data and also to print individual 1 by one the elements but not the arrays. I have an idea in my mind on how to solve it. I did not had the time to work on it, that is the reason that I have not updated my solution.

But thanks again for your time and effort and sorry if my sketch is not so clear.
