Hi tsk1979 ,

There is a module List::Compare will do that work. 

use strict;
use warnings;
use List::Compare;

my @a = qw(-true -depth=1);
my @b = qw(-search -depth=1 -true -expand_all) ;

 

my $lc = List::Compare->new( \@a, \@b );

my @a_only = $lc->get_Lonly;
my @b_only = $lc->get_Ronly;

print join( ', ', @a_only ), "\n"; # 1, 2

@a_only ? print "@a_only" : print "\nAll Matched";
