Linux 建议学习路径[转]

摘要：建议学习路径：首先先学学编辑器，vim, emacs什么的都行。然后学make file文件，只要知道一点就行，这样就可以准备编程序了。然后看看《C程序设计语言》K&R，这样呢，基本上就可以进行一般的编程了，顺便找本数据结构的书来看。如果想学习UNIX/LINUX的编程->《APUE》绝对经典的教材，加深一下功底，学习《UNP》的第二卷。这样基本上系统方面的就可以掌握了。然后再看Douglus E. Comer的《用TCP/IP进行网际互连》第一卷，学习一下网络的知识，再看《UNP》的第一卷，不仅学习网络编程，而且对系统编程的一些常用的技巧就很熟悉了，如果继续网络编程，建议看《T 阅读全文
