System administrators need libraries of solutions that are ingenious but understandable. They don’t want to reinvent the wheel, but they don’t want to reinvent filesystem management either! Expert Shell Scripting is the ultimate resource for all working Linux, Unix, and OS X system administrators who would like to have short, succinct, and powerful shell implementations of tricky system scripting tasks. Automating small to medium system management tasks Analyzing system data and editing configuration files Scripting Linux, Unix, and OS X applications using bash, ksh, et al. What you’ll learn Debug shell scripts using existing debuggers, not inspection. Use and extend text–editing one–liners and learn to forget Perl. Manage files and filesystems using scripting, not inflexible utilities. Use scripts to build complete Linux systems. Script X Window without getting lost in configuration files. Ignore Python, and script in bash and ksh instead.

本书旨在为Linux、Unix以及OS X系统管理员提供短小精悍且功能强大的shell实现解决方案，教会读者如何使用现有调试器调试shell脚本。 全书分为3个部分：脚本技术基础、系统交互和高级技术、有用的脚本实例。主要内容包括如何使小到中型的系统管理任务自动化，分析系统数据并编辑配置文件，使用bash和ksh等编写Linux、Unix和OS X应用程序的脚本文件等。 本书面向中高级的shell程序员，以及需要解决日常问题的系统管理员，但假定读者能够读懂一般的shell代码。
