  • Rather than "or" you should be using a defined-or, or a length test on the array of the given file.

    Otherwise, strings like "0" and "0.0" will not be printed.
    • He's not chomping, so the newline on the end will make the string true. (Also, "0.0" as a string would be true.)

        Correct. The bug I'm trying to fix is that nth 100 /dev/null doesn't print anything. If you're trying to correlate the results from a list of files, and some files don't produce n lines of data, then you should at least print something, or else there will be a non-deterministic mapping of values. (Specifically, the results from $ join filenames results will be way off...)
