2016_10_26_阶段性感悟

阶段性学习感悟:

• 在接触linux的几年时间里,总是在看着书籍或者学习视频,跟着进行操作,突然有一天会发现,知晓的linux命令不算少(当然跟大神相比还是有所差距的),但还是感觉廷杂乱,不系统.

---

• 因此,我有一个想法,把学习的命令系统的整理以下,当然这些命令不是我自行编造,依据操作系统里面总结的英文文档(info coreutils 'uname invocation'命令可查看),参考现有的中文书籍(鸟哥私房菜).

---

• 这个计划是准备在两年时间完成,后面我的博客中以xxx那些事儿格式为名的博客均属该计划内(此名称来源于一技术者的电台名称软件那些事儿为原型).

• 如何更好的学习linux?
  what?when?how?why?

• 如何思考报错问题?
  your input, what you expected, what you got, and why it is wrong
