3分钟搞懂Linux基础命令:从创建文件到删除目录,新手一篇就入门

很多人菜鸟第一次接触 Linux，看到终端窗口满屏的命令，不由的反应：这东西到底怎么用？

其实 Linux 入门并没有我们想象中那么难。

其实你能搞懂这几个基础的命令，就可以完成日常最常见的文件操作：

创建目录、查看文件、切换目录、创建文件、修改文件和删除文件。

与其一个劲的研究复杂的原理，去死记硬背Linux的所有命令。

就用 3 分钟，打开虚拟机，连接到 Linux 系统。我们练习一下 Linux 中常用的文件操作命令，不管你用的是 Ubuntu 还是 CentOS 还是 Debian，操作命令都是一样的。

跟着一起敲下面这些基础命令，你Linux也算基础入门了！
纸上谈兵得来的知识终究浅薄，菜鸟到老炮的进化，其中最少不了的是实操，所有上面代码反复练，重复练，直到肌肉记忆，你也可以成为运维大佬
