dvinay,

I could't help but notice that your array just screams to be an array of arrays. I say this because it regularly repeats itself every three elements. I know this wasn't your original spec, but I offer the following advice.

If you structured your array as:


my @array = qw/ create  mount  remove /;
my $array = [
  ['create', 'mount', 'remove'],
  ['create', 'mount', 'remove'],
  \@array,    # essentially the same values
  \@array,
  ...
];

... then you could easily add items to the end of each of sub-array by iterating and pushing:

#!/perl/bin/perl
use strict;
use warnings;
use Data::Dumper;

for my $subarray (@$array) {
  push(@$subarray, 'foo');
}

print Dumper($array);

            'create',
            'mount',
            'remove',
            'foo'
          ],
          [
            'create',
            'mount',
            'remove',
            'foo'
          ],
          [
            'create',
            'mount',
            'remove',
            'foo'
          ],
          [
            'create',
            'mount',
            'remove',
            'foo'
          ],
        ];
