读后感
这不是我想要的Shell入门，因为它没有让我感受到一丝Shell的魅力，通篇只有细节，而且讲述不清（比如对getopts里OPTARG(在bash 3.2里好像是OPTSTRING)的讲解，让我一度很困惑，这个序列存的参数到底是以词为单位呢，还是字符），缺乏比较（比如文中似乎没有关于$(()), $[], [],...
评分行文很生硬，很多地方甚至连基本的文法句法都不通——可以通过提取主干主谓宾来验证。 如果不是同时在看另外一本讲Shell的书，仅仅是通过这本来了解Shell的话，我很可能就悲剧了，这本书糟糕的翻译会让我我误以为Shell本身是一门艰深的技术，从而一直止步于门外。这也是所有同...
评分应该说，bash这类shell脚本的学习书籍，涉及的内容会比较杂，很高兴作者把这些杂乱的内容有序的组织到这本书里。 应该说，这本书读起来应该不会很吃力，因为对bash的介绍很多也就是对linux操作系统，特别是和shell相关部分的介绍，而且很多人对linux/unix的最直观和直接的操...

评分看完这本书，可是里面的题目有些不会^^^^^，后面几章的课后习题没有解答，对我这种菜鸟有点难度啊…… 深入的学习shell script，看什么？？ ABS吗？
用户评价
这本书适合*nix系统管理员、*nix程序员学习如何编写Bash脚本，至少比man bash那个5千多页的文档强多了。看了一遍并将所有task敲了一遍，大部分扩展练习没做，有些确实很难。没太多时间花在bash上，就先这么着。
评分又一次见证了看书的力量
评分为了写一个小function而看了这本书的前8章。 感觉写得不错，基本一边看一边写最后也写出来了。看完以后再看别人写的天书一般的script终于能稍微理解一点了。不过我觉得shell script不用深究，只要能看懂大致即可。真需要用到的时候去网上找找就行。
评分浅显易懂，但示例的深度不足。
