If it was a c++ code then i would have done something like this : open my $fh, '<', 'C:\ppp.txt', or die "Could not open file $!"; if ($fh contains an empty file) { // then add this the $address in the ppp.txt's first line }
This is easy in Perl: 
my $file = 'c:\ppp.txt';
if (-e -z $file) {
   warn "$file exists but is zero sized!\n";
   open my $tmp, '>', $file or die "cannot write to $file!\n";
   #
   #write what you need to
   close $tmp
}
