Quite amazing that i get couple of good answers for my previous questions.

I use regex quite often, and used it in various linux tools such as vi, sed, perl, grep... And mostly use in perl. Can somebody tell me how to relate all those ? As because most of the parts of regex are similar in all tools, and some of them are different in different tools. What are all they, and how to relate.

Though it is not very specific to Perl, i believe some Perl expert will have this understanding, so expecting some guidance in that area.
