      Hi, You are correct :-)
      I ran the perl with the B::Deparse module
      Perl parses the line 
      truncate $fh,0 || die "could not truncate $dcs_log_file: $!";

      [download]
      to 
       truncate $fh, die("could not truncate ${log_file}: $!");

      [download]
      Now i also understand the difference between || and or :-)

      In || it makes 0|| before truncate.
      with or it would make the truncate before

      Thanks,
      David
