Hello Laurent_R,

Thanks a lot for the link. In my case time is not an issue but I ques when files while start to grow, the time will start to be an important factor. Again thank you for your time and effort it is really nice that people offer advice on such a small issues that are easy to understand. At least for beginners like me.

Seeking for Perl wisdom...on the process of learning...not there...yet!
