Yes, it just copies the files. If you want to change them in the process then something like this 
#!perl
use strict;
opendir(DIR,'../input') or die "$!";
while (readdir DIR){
  unless (/^[.]{1,2}$/){
    print "parsing $_\n";
    open IN,'<','../input/'.$_ 
      or die "Could not open $_ for input : $!";
    open OUT,'>','../output/'.$_ 
      or die "Could not open $_ for output : $!";
    while (my $line = <IN>){
      # process $line
      print OUT $line;
    }
    close IN; close OUT;
  }
}
