No one can give helps unless he also know this special algorithm.

Recently, when I want to implement Chakrabarti's algorithm

I can make my program do its job at last, but it runs slowly.

Concurrent processes can be counterintuitive at times. Because the
CHILD filehandle is buffered, that line won't necessarily be sent to
the child process right away. In your program, I'd expe

Hello all!
I've come to a point where I really need to start understanding
forking, threaded, select, and all that stuff. I created a test
script to play around with and it's doing what I'd expect, except for
one bit. My test script:
use strict;
use warnings;
print "First Trial:\n\n";

1. Divide by five.
2. Round to the nearest integer.
3. Multiply by five.
4. Profit!
Hope this helps!

I have been working on this script to extract information based on group

Am I missing something because it never finds E$ in any of the files I'm
