Hi Gunner,
Thanks for your reply. It works out if I use qw option. However I have
bigger list. I am sending my program, it provides me both *_d.t.Z as
well as *Z list. Not doing the comparison. Can you have a look again?
So looks like the comparison is not working.
Thanks in advance.

$KIT_LOCATION="/lnx/dep/packages";
$KIT_LIST=`ls $KIT_LOCATION/*.t.Z`;
#print $KIT_LIST;
$KIT_LIST=~ s/$KIT_LOCATION\///g;
#print $KIT_LIST;
my @kits = $KIT_LIST;
chomp ($kits);
#print "@kits";###prints out both .Z and _d.t.Z

     my %hash = map {
        ( my $tmp = $_) =~ s/_d(\.t\.Z)$/$1/; $tmp => 1
     } grep /_d\.t\.Z$/, @kits;


        #print "@kits\n"; #prints out both .Z and _d.t.Z

     foreach my $kit ( grep !/_d\.t\.Z$/, @kits ) {
         #print "$kit\n" unless $hash{$kit}; #prints out both .Z and
_d.t.Z
     }
