In this preface, I’ll tell you about the history of Minimal Perl and the origins of this book. THE HISTORY OF MINIMAL PERL The seeds of this book were sown many years ago, when I was building up my knowl- edge of Perl, the greatest programming language I’d ever encountered (before or since). While reading a variety of books on the subject, I was surprised that the authors felt obliged to delve into so many of the different but equivalent choices for expressing every basic operation in the language, as well as each of the syntactic variations for expressing any one of those choices. As an example, I’ve shown here some of the available choices for expressing in Perl the simple idea that B should be executed only if A is True (with those letters repre- senting arbitrary program elements). Both forward and backward variations for expressing the dependency are included:1 Although some are inclined to present symptoms like these of Perl’s complexity and redundancy as evidence of its “richness,” “versatility,” or “expressiveness,” many Perl novices would surely have a different reaction—that Perl is needlessly complex and too hard to learn. Minimal Perl was created to address these obstacles presented by Perl’s redundancy and complexity. By emphasizing Perl’s grep, sed, and awk-like features, and relying Forward Backward A and B; B if A; A && B; B if A; A and do { B }; do { B } if A; A && do { B }; do { B } if A; if (A) { B }; B if A; unless (!A) { B }; B unless !A; 1Before you despair, I should point out that Minimal Perl uses only 2 of these variations—which is all anybody needs! xx on concepts such as inputs, filters, and arguments, it allows Unix1 users to directly apply their existing knowledge to the task of learning Perl. So rather than being frustrated with Perl’s complexities and disappointed with its steep learning curve, they quickly and painlessly acquire the ability to write useful programs that can solve a wide variety of problems.

Cygwin是一个在windows平台上运行的类UNIX模拟环境,是cygnus solutions公司开发的自由软件(该公司开发的著名工具还有eCos,不过现已被Redhat收购)。它对于学习UNIX/Linux操作环境,或者从UNIX到Windows的应用程序移植,或者进行某些特殊的开发工作,尤其是使用GNU工具集在Windows上进行嵌入式系统开发,非常有用。随着嵌入式系统开发在国内日渐流行,越来越多的开发者对Cygwin产生了兴趣。解压后,请按照备注文档操作。

Python is an ideal language for solving problems, especially for Linux and Unix. With this pragmatic book, administrators can review various tasks that often occur in the management of these systems, and learn how Python can provide a more efficient way to handle them. Once you finish this book, you'll be able to develop your own set of command-line utilities with Python to tackle a wide range of problems.
