程序员必备的Linux命令——磁盘和文件系统

Linux命令就是我们对Linux系统进行管理的操作指令。类似于我们操作windows系统中可视化的各种操作动作。

在Linux系统中，我们任何东西都被认做是文件，比如cpu、内存、键盘以及用户全是文件。Linux命令类似于之前的DOS命令。

Linux系统中命令分为两种：Linux命令以及Shell命令。

小步慢跑，一天10——20条命令，好好消化，基本的linux操作命令信手拈来

上一篇程序员必备的Linux命令——查看文件及内容处理 对文件及内容的操作指令，今天我们看一下磁盘和文件系统的处理命令

以上命令是对磁盘及文件系统的命令，这些命令也是需要配置他的权限授权，如果没有权限，即使命令写的再好，也是不能够运行的，下面再给大家添加4个权限和用户授权的相关命令
