You don't need to load the whole file into memory, but just as many lines as there are in your search string. So you can use the following approach:

  1. read n lines
  2. do pattern match
  3. remove the first line
  4. read one more line
  5. goto 2

  • 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.
