Subject: One-liner removing duplicate lines

Hello,

Converting from Perl to Ruby, I am trying to find an equivalent to this
Perl one-liner removing duplicate lines in a file (without sorting it at
first) :

   perl -ne'$s{$_}++||print' infile >outfile

I guess uniq method could be used, but I can't find how.


Many thanks in advance,
