Your GetOptions call puts the pathnames of the files in the variables $input and $output. So now you just need to open those files and do stuff with them: 

open my $in, '<', $input or die $!;
open my $out, '>', $output or die $!;
while(<$in>){
  # do stuff to $_
  print $out $_;  # or whatever output you come up with
}
