写学习日记，这是学习历程的见证，同时我坚持认为是增强学习信念的法宝。

硬盘安装及光盘安装，清楚了解安装Linux应注意的有关问题，如安装Linux应在最后一个分区内，至少分二个分区。

一定要学好命令，shell是命令语言，命令解释程序及程序设计语言的统称，shell也负责用户和操作系统之间的沟通。

选择交流平台，如QQ群，网站论坛等。

选择一些适于初学者的Linux社区。

我感觉linux的学习,学习编程~!~!就去学习C语言编程!!

一定要学好命令，shell是命令语言，命令解释程序及程序设计语言的统称，shell也负责用户和操作系统之间的沟通。

为什么要学Linux呢？每个人都有不同的看法，下面我说说自己的感想吧。?
