Just open an output file and print whatever you want to save off to that handle. perldoc perlopentut and perldoc -f open will explain more.

Also, a style nit: using -r and friends on files you're about to open is redundant. Just open them and then deal with that failing. 

open( FILE, $filename ) 
  or die "Can't open $filename for reading: $!\n";
...

Or something like this which is handy when you're looping over several files

foreach my $filename ( @files ) {
  unless( open( FILE, $filename ) ) {
    warn "Couldn't open $filename: $!\n";
    next;
  }  

  ...

  close( FILE );
}

Not using the test operators gets even more important when you get into writing files, since test-then-open isn't an atomic operation and you leave yourself open to race conditions.
