Perl语言入门（第四版）（英文影印版） (2008 年度畅销榜NO.2576 )

《Perl语言入门，第四版》与其他“骆驼丛书”一样，引领了许多Perl程序员从入门走向精通。本书出自三个Perl社区的卓越成员之手——他们拥有多年从事Perl培训的丰富经验，同时本书针对最新的Perl 5.8版本做了相应的修订。
Perl是为高效工作而设计的。开始时，它只是Unix的系统管理员快速完成一些简单任务的工具，渐渐地，它发展成为了一种跨平台的、功能强大的编程语言，被频繁地应用于网站开发、数据库处理、XML处理和系统管理等等。同时，它作为快速的开发工具在日常工作中仍被广泛使用。也许，你是偶然地进入Perl程序开发领域，但我们相信Perl的简洁特性和强大功能将使你爱不释手。
基于多年Perl咨询的成功经验，作者重新修订了此书，不但保留了原书中详尽的讨论、丰富的实例和独特的理解，而且让本书也适合于初学者。
《Perl语言入门，第四版》包括了许多新的练习和解决方案，相信你可以从中学到许多新知识，本书主要涵盖以下内容：
* 数据结构
* 最小匹配
* 线程
* 数据解析
* 引用
* 对象
* 模块
* 打包实现
今天，如果问Perl程序员哪本书是他们最依赖的参考书籍，绝大多数的回答是——“骆驼丛书”。最好的理由是，这本书能教你成为一名真正的Perl程序员，而不仅仅像其他参考书一样告诉你如何编写Perl程序。
