What do you mean by compare? Could you give an example?
You may use array of arrays to hold your input file.

For example:

1. Generate some data (this is zsh):

Code:
[11:50][dimitre@ubuntu][/home/dimitre/t]$ for j ({1..6}) {
  for i ({1..7}) {
    printf "%d " $((RANDOM%100))
    }
  print
  }
84 90 86 48 19 94 38 
69 64 65 23 81 57 6 
25 72 6 62 72 94 97 
21 97 20 36 10 34 14 
25 27 91 41 49 77 90 
0 3 60 1 68 26 24

Use AoA to hold your arrays (the numbers do not match, because I'm using the RANDOM variable):

Code:
[11:51][dimitre@ubuntu][/home/dimitre/t]$ for j ({1..6}) {
  for i ({1..7}) {
    printf "%d " $((RANDOM%100))
    }
  print
  } | perl -MData::Dumper -lane'
  push @arrays, [@F];
  print Dumper \@arrays if eof
  ' infile
$VAR1 = [
          [
            '39',
            '76',
            '75',
            '11',
            '37',
            '0',
            '6'
          ],
          [
            '19',
            '23',
            '8',
            '66',
            '84',
            '24',
            '53'
          ],
          [
            '35',
            '79',
            '23',
            '27',
            '82',
            '90',
            '2'
          ],
          [
            '80',
            '27',
            '24',
            '59',
            '10',
            '25',
            '12'
          ],
          [
            '79',
            '91',
            '54',

Pod::Simple::LinkSection(3)				User Contributed Perl Documentation			       Pod::Simple::LinkSection(3)

NAME
Pod::Simple::LinkSection -- represent "section" attributes of L codes SYNOPSIS
# a long story DESCRIPTION
This class is not of interest to general users. Pod::Simple uses this class for representing the value of the "section" attribute of "L" start-element events. Most applications can just use the normal stringification of objects of this class; they stringify to just the text content of the section, such as "foo" for "L<Stuff/foo>", and "bar" for "L<Stuff/bI<ar>>". However, anyone particularly interested in getting the full value of the treelet, can just traverse the content of the treeleet @$treelet_object. To wit: % perl -MData::Dumper -e "use base qw(Pod::Simple::Methody); sub start_L { print Dumper($_[1]{'section'} ) } __PACKAGE__->new->parse_string_document('=head1 L<Foo/bI<ar>baz>>') " Output: $VAR1 = bless( [ '', {}, 'b', bless( [ 'I', {}, 'ar' ], 'Pod::Simple::LinkSection' ), 'baz' ], 'Pod::Simple::LinkSection' ); But stringify it and you get just the text content: % perl -MData::Dumper -e "use base qw(Pod::Simple::Methody); sub start_L { print Dumper( '' . $_[1]{'section'} ) } __PACKAGE__->new->parse_string_document('=head1 L<Foo/bI<ar>baz>>') " Output: $VAR1 = 'barbaz'; SEE ALSO
