"read file line" in the title for SoPW turns up: Line number in a file, reading a particular line in a large text file, Best way to read line x from a file, Reading Lines from Text file and reading a random line from a file among many many others. This is not an infrequently asked question.

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