in reply to how to ignore spaces, commas or new line of an array when comparing

That almost sounds like the use case for the WhiteSpace option. Did you try that?

If you still have problems, I recommend that you show precisely how your arrays are created. eg:

my @array1 = ('abc ', 'xyz');

... and so on. This removes any ambiguity about the data you actually have.

    in @array1, the contents are being pushed and in @array2, the contents are being read from a file and stored in the @array2

      How does that reply address "show precisely how your arrays are created" (see I know what I mean. Why don't you?)? Perhaps you intended to write something like:

      use strict;
use warnings;

my $fStr = <<FSTR;
abc
   xyz
FSTR

open my $inFile, '<', \$fStr;
my @array2 = <$inFile>;
my @array1 = ('abc ', 'xyz');

      Hmmm. Is your real question then "How do I clean whitespace from data read from a file?" or something like that? Or do you really want one array with whitespace and one without?
