Re: Filtering very large files using Tie::File

[biohisham]

I also found array-based dupe stripping solutions.....

C:\Documents and Settings\franciscor>perl -
use List::MoreUtils qw(uniq);
my @list = qw(3 1 2 1 3 4 1 5 1 6 8 1 2 1 2 7 1 1 2 3 4 6 1);
my @unique = uniq(@list);
print "@unique";
__END__
3 1 2 4 5 6 8 7

Thanks, that's pretty elegant, but it filters on the whole record, not the first two fields as I need it to, so I'll stick with the solution suggested by Corion.
