It is not a bad technique because the goal is to abstract away the operating sytem and then program in your abstraction. File::Spec provides part of such an abstraction. (Perl provides most of the rest...)

to format your post, it's "PerlMonks-approved HTML":


  • 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.
  • Please read these before you post! —
