How can I compare arrays in Perl?

Question

I have two arrays, @a and @b. I want to do a compare among the elements of the two arrays.

my @a = qw\"abc def efg ghy klm ghn\";
m         


        

Answer 1

my @a = qw' abc def efg ghy klm ghn ';
my @b = qw' def ghy jgk lom com klm ';

my $flag;

foreach  my $item(@a) {
  $flag = @b~~$item ? 0 : 1;
  last if !$flag;
}

Note that you will need Perl 5.10, or later, to use the smart match operator (~~) .
