Yet another way to do it:

You might want to sort both files on the key of interest. Then you can scan through the files side-by-side and print the appropriate items--just like a merge sort.

I recently responded to a similar question which you might want to look at if you're interested in this method--it has an example program in it that could easily be modified to handle your problem.

  • 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.
