linux挂载命令mount及U盘、移动硬盘的挂载

一.mount的命令格式是（注意mount只能在root权限下运行）

mount dervice dir

dervice是要挂载的设备，dir是挂载点

二.查看当前磁盘列表的设备

fdisk -l

显示如下信息

root@kali:~# fdisk -l

这里我们可以看到所有连接在电脑上的设备和分区情况，比如我们想挂载/dev/sda5

三.创建挂载点

mkdir /mnt/diskd
mount /dev/sda5 /mnt/diskd

挂载成功

四.弹出设备

umount /dev/sda5

 通过df可以查看设备挂载点
