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...

评分确实是Learning系列的书，所以非常的浅显易懂。 适合没有什么Shell实用经验的人。 可以很快对Bash有一个整体的概念，并且能够做一些简单的工作。 看完了书，还需要很多的实际解决问题的经验才行。
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。
评分讲的很有条理，建议配合BASH手册来读。
评分絮絮叨叨意识流写作
评分CH1-8, 10-12
评分讲得很容易懂，不过我不喜欢作者说因为有些操作不安全就不要做的观点。因为他给的建议也不安全。
