Thanks for taking your time to look over my code. Like I said, I am new to Perl and would like to learn how to do multiple tasks using Perl so I self taught myself and didn't learn this language from school or book. You are correct, I should remove the lines "used File::Copy? Or Cwd:" since I don't know what they mean. I was copy the template from other blogs and forgot to remove them. I want to use the "my $dir.." because I want to verify and make the files that I am working on are in the same directory as the Perl scrip. I used sub main because I need to the script to do multiple tasks after it is merging. Thanks gain.
