I have said that I have no time for command-line perl. What you have published
doesn't work on my platform, nor on many others.
Of course I could rewrite the question in my head to a proper Perl program, but
then I shall be looking for a bug either in my mental rewrite or in your
original code.
So since you can't be bothered to publish a proper Perl program, neither can I
be bothered to interpret your question. What is more, nor will all the other
people who could have answered your question wisely.
