One way:
To find out elements which are in test2 and not in test1:
#!-*-perl-*-<ur perl path>
use strict;
my @test1 = qw(1 2 3 4);
my @test2 = qw(1 2 5 6 7 8);
foreach my $element(@test2) {
print $element if([EMAIL PROTECTED]);
}

Subject: compare, checking and listing
Hi,
I have two array, @test1, @test2. Just say, I want compare @test2 with
@test1 in such manner. @test2 could contains more, less or equal
elements compare to @test1 which I don't know.
I want to write a perl script to compare @test2 to @test1 and list out
those element within @test2 that is not represent within @ test1 and
those elements within @test1 that has not found the match from the
@test2
How do I accomplish such task efficiently?
Thank you & best regards,
ABC
