## 使用指南<a name="section04"></a>

mount后加需要挂载的设备信息、指定目录以及设备文件格式，就能成功挂载文件系统到指定目录。

## 使用实例<a name="section05"></a>

举例：mount -t nfs 192.168.1.3:/nfs nfs

## 输出说明<a name="section06"></a>

**示例 1** 将服务器端nfs目录192.168.1.3:/nfs挂载到当前系统下新建的/nfs目录：

```shell
OHOS:/$ mkdir nfs
OHOS:/$ mount -t nfs 192.168.1.3:/nfs nfs
Mount nfs on 192.168.1.3:/nfs, uid:0, gid:0
Mount nfs finished.
OHOS:/$ ls nfs/
16d.xml         gpio_test             ohos_test.txt    userfs_vfat.img
OHOS_Image.bin  hello                 rootfs_vfat.img
dev_tools       mksh_rootfs_vfat.img  test_demo
```
