It is impossible to modify any type of file "in-place" unless the replacement fields each have exactly the same number of characters as the fields they replace. Even in that case it is usually easier to copy and rename the file as you suggested. The details often be handled automatically. (Refer to runtime options -i and -p in perldoc perlrun)

  • 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.
