"i copied manually 3 examples of that book and they all came with a bug in the lines of those diferent programs, i ask are all the examples in perl cookbook, are broken, not working, needing debugg??"
Unless you describe the problems you're experiencing there's little anyone can do to help. Work through Basic debugging checklist, PerlMonks for the Absolute Beginner and How do I post a question effectively?. Consider posting the code and the output from running the code. N.B. proper formatting makes it easier for people to help you.

O'Reilly, being such a great publisher, provides errata and all examples for download under http://shop.oreilly.com/product/9781565922433.do. (See essential links on the right hand side.) So need for typing. Check for bugs there first.
Otherwise, please be welcome to post any specific(!) question in this forum!

You must have been very unlucky. There may be some bugs in some of the programs, of course, but I am pretty sure that they are quite uncommon, actually very rare. I have been using both the first and the second editions of this book in the past, there may be outdated features, but I haven't seen any real bug that I can remember of. It is definitely a book that I would warmly recommend. Perhaps the problem is that the code snippets presented in this book are rarely complete programs, or perhaps you overlooked something and mistyped the example. Or perhaps you are using a completely different version of Perl. Or maybe platform-dependent features.
I would add that Tom C. and Nat T. are very well know Perl authors, with an excellent reputation, and I firmly believe that they are doing they work very seriously. They also state the following in their preface: "We tested most programs and examples under BSD, Linux, and SunOS, but that doesn't mean they'll work only on those systems. Perl was designed for platform independence. " In addition O'Reilly's editors are also known to do their work very seriously. To me, O'Reilly is one of the best publishers in the field of IT.
OK, this response can only be very general. I would suggest that you post the programs that have bugs in your eyes (also explaining where the bug is in your mind), so that we can make a judgment on these bugs and provide a more specific answer.

Iam going to buy the book Perl Cookbook on amazon, because i live in Lisboa, so ti buy it i have to use amazon.com, there are no copies of the Perl Cookbook in Lisboa, i checked.
I wanted a opinion, the only thing know is to wait to pay day in the end of the moth, normal pay day in Portugal.

All right, but it would still be of interest for everyone, and especially for you, if you posted the programs that you think are wrong or bugged (which they may be, I certainly don't rule that out).
