Re^2: Removal of duplicated element in array.

I tried my @match_to_array = split (/\n/,$match); , the \n are not preserved.

my @r = keys { map { $_ => 1 } split /\n/, $match }; has " Type of arg 1to keys must be hash (not annonymous hash ) " error.

Guess I did something wrong for the -rep ? Sorry If I did so.

Might be that you are using an older version of Perl? I'm on 5.16. Here is a two line version: `my %seen = map { $_ => 1 } split /\n/, $match; my @r = keys %seen;` [download] Hope this now works for you. And I still assume that you want to get rid of the \n? Apologies for any confusion I caused.	[reply] [d/l]

Yup, I am using Perl v5.10.1 . The \n is simply for readability purposes, so if it isn't there, it is still alright. The output of your code outputs the same result as the input with duplicates.	[reply]
