Today I dugg very interesting site about regular expressions. There are many useful information about regexps such as: complete regexp tutorial, links to useful tools and regexp libraries for almost all programming languages.

I think, regular expressions and unix shell are the must to know for any IT professional because they can greatly improve your performance in routine tasks. Even my wife - web designer - some times uses regexps in her favourite html-editor for massive links/tags replacements.

So, if you do not know anything about regexp yet, it is really good deal to get knowledge about professional text-processing tool - regular expressions.
