$text =~ /Host System (?!#)/ is correct too. However, [^#] is probably faster and an acceptable replacement in this case.

The problem is
if $text =~ /Host System (?!#)/ next;
was used instead of
if ($text =~ /Host System (?!#)/) { next; }
or
next if ($text =~ /Host System (?!#)/);
or
next if $text =~ /Host System (?!#)/;

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
