In a comment to this post: output from an external program, brother merlyn gives a pretty good example on how to use pipes when you want to write to and read from the same program without having to think about deadlocks. It should easily be adaptable to other scenarios as well.

  • 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! —
  • Posts may use any of the Perl Monks Approved HTML tags:
