uniq array creation

[Sunita Pradhan]

Hi 
I want to create a unique array . 
I have the code below. It is creating a array which will have duplicate data . 
How can I filter duplicate data ?
#!/usr/bin/perl

use Data::Dumper;

 

#my $cnt = scalar @$net_int_parsed_output;
$net_int_parsed_output = [lif_1 ,lif_2,lif_3,lif_4,lif_1,lif_2]; foreach my $n
(@$net_int_parsed_output){

        my
$lif_cnt++;

        print
"lif of vserver >>> $n\n";

               
push
(@{$lun_PR_resv_info->{'lun'}->{'vserver'}->{'fcp_lifs'}},$n);

}

 

print "lun PR resv related
info>>>>>>>>>>>>>",Dumper
$lun_PR_resv_info,"\n";
ThanksSunita
