You received all good answers, but I suspect that you need to clarify/update your question to get the answer you may still need. For instance,

  • does your file constantly change or is it static?
  • will it increase to a size that is greater than the memory in your computer?
  • does it need to run during prime time or can it run off-shift?
  • can you use a data base to do the seeking for you?

    None of these has anything to do with perl directly, but for perl to work correctly for you, questions like these need to be determined by you

    But if you have the answer you want, then have a great day.

    Good Luck
