Hi Monks!

I am trying to open a text file and check if the first line has no header, it will be blank and replace this blank line with this line with are the header as you can see in the code posted. I know I am missing something cause nothing is happening.
I can not change the name of the original file. Any help would be very appreciated! 
#!/usr/bin/perl

use strict;
use warnings;

 my $filename = 'dir/people.txt';
 
 open(my $fh_out, '>', $filename) or die "Could not open file out '$fi
+lename' $!";
 open(my $fh_in, '<', $filename) or die "Could not open file in'$filen
+ame' $!";

 # Read in line at a time
 while( my $line = <$fh_in> ) {

    # If the file start with blank line replace it with these headers
   if ( $line =~ /^\S/ ) {

       print $fh_out, "Name, City, State, Zip";
       
   }
 }
 close $fh_in;
 close $fh_out;

Text file:
my $file =
"
JOHND,NY,NY,11111
MARY,SOMEWHERE,OK,22222

I would like to add the header if the file doesn't have one:
Name,City,State,Zip
JOHND,NY,NY,11111
MARY,SOMEWHERE,OK,22222
JOE,LONDON,LO,33444

Thanks for helping out!; open(my $fh_out,
