I have written a simple perl script:

#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

$Data::Dumper::Pair     = '';
$Data::Dumper::Sortkeys = 1;
$Data::Dumper::Terse    = 1;

my @A=( [ 1,2 ],[ 3,4,5 ], [ 6,7,8 ]);
print Dumper(@A);

The output i get is :

> ./temp9.pl
[
          1,
          2
        ]
[
          3,
          4,
          5
        ]
[
          6,
          7,
          8
        ]

But what i need is the elements(arrays) to be separated with a comma , in between them. I am much familiar in using Data:Dumper. Is there any fix for this? The expected output is :

[
          1,
          2
        ],
[
          3,
          4,
          5
        ],
[
          6,
          7,
          8
        ]

Anothere question i have is is there any way in data dumper where i can add some text before each element in an array?for example here in array of array , can i add "xyz" before the opening brace of each array?

Try with print 'my $aRef = ', Dumper(\@A), ";";. It will print like this:

my $aRef = [
  [
    1,
    2
  ],
  [
    3,
    4,
    5
  ],
  [
    6,
    7,
    8P
  ]
]
;

If You want to change the output of Dumper you can redirect the stdout to a variable (see open).

print map { "Something $_\n" } split "\n", Dumper(\@A);

Output:

Something [
Something   [
Something     1,
Something     2
Something   ],
Something   [
Something     3,
Something     4,
Something     5
Something   ],
Something   [
Something     6,
Something     7,
Something     8
Something   ]
Something ]
