I have an array @name with the below contents (index 7 and 8 are names):

1|1|2|2|I|2|0|DUNN|LACY||||||
2|2|2|2|I|2|0|KOFE|ROGER||||||
3|3|2|2|A|2|0|KOFOED|ROBERT||||||
3|4|2|2|A|2|0|KOFOED|ROBERT||||||
3|5|2|2|A|2|0|KOFOED|ROBERT||||||
2|7|2|2|I|2|0|WILLIAMSON|JAMES||||||
3|8|2|2|I|2|0|MUNN|MARION||||||
4|9|2|2|A|2|0|BLOCK|ROY||||||

I want to remove the duplicates, from the list @name:

1|1|2|2|I|2|0|DUNN|LACY||||||
2|2|2|2|I|2|0|KOFE|ROGER||||||
3|3|2|2|A|2|0|KOFOED|ROBERT||||||
2|7|2|2|I|2|0|WILLIAMSON|JAMES||||||
3|8|2|2|I|2|0|MUNN|MARION||||||
4|9|2|2|A|2|0|BLOCK|ROY||||||

I need help with a unique list of names (ignore the other fields).

Thanks,

What programming language you're using?

this is perl

I'm not sure if this is an array or input.
Anyway, consider the following approach:

#! /usr/bin/perl

use warnings;
use strict;

my %Seen;

while (<DATA>) {
  print unless $Seen{(split /\|/)[7,8]}++;
  }


__DATA__
1|1|2|2|I|2|0|DUNN|LACY||||||
2|2|2|2|I|2|0|KOFE|ROGER||||||
3|3|2|2|A|2|0|KOFOED|ROBERT||||||
3|4|2|2|A|2|0|KOFOED|ROBERT||||||
3|5|2|2|A|2|0|KOFOED|ROBERT||||||
2|7|2|2|I|2|0|WILLIAMSON|JAMES||||||
3|8|2|2|I|2|0|MUNN|MARION||||||
4|9|2|2|A|2|0|BLOCK|ROY||||||

$ ./p  
1|1|2|2|I|2|0|DUNN|LACY||||||
2|2|2|2|I|2|0|KOFE|ROGER||||||
3|3|2|2|A|2|0|KOFOED|ROBERT||||||
2|7|2|2|I|2|0|WILLIAMSON|JAMES||||||
3|8|2|2|I|2|0|MUNN|MARION||||||
4|9|2|2|A|2|0|BLOCK|ROY||||||

This will be an array
