怎样移动富士山？这个问题是比尔·盖茨对那些渴望应聘微软公司的大学毕业生提出的一道面试题。而对此，比尔·盖茨的解释是：它没有固定的正确答案，我只想了解这些年轻人有没有按照正确的思维方式去思考问题。

据说是唐骏亲自出的微软面试题--答出一道题，微软就会录用；答对两道题，微软可以开出双倍的工资；答对三道题，就可以自己给自己开工资了。

Perl is a relatively unstructured language. Although it does, of course, have rules, most of the restrictions and rules that you may be used to in other languages are not so heavily enforced. For example, you don’t need to worry too much about telling Perl what you are expecting to do with your program (or script or application), or what variable’s subroutines or other elements you are either going to use or introduce. This approach leads to what is called “There Is More Than One Way to Do It” (TIMTOWTDI, or tim toady for short) syndrome—which refers to the fact that there are different ways of achieving the same result, all of which are legally valid.

Perl is a powerful programming language that grew out of the traditional system administration toolbox. Over the years it has adapted and expanded to meet the challenges of new operating systems and new tasks. Until now, however, no book has recognized this deep history by concentrating solely on using Perl for system administration. If you know a little Perl, and you need to perform system administration tasks, this is the right book for you. Readers with varying levels of both Perl programming experience and system administration experience will all find something of use within these pages.
