## Usage Guidelines

By specifying the device to mount, directory, and file system format in the **mount** command, you can successfully mount the file system to the specified directory.

## Note

Currently, the shell does not support this command. mksh supports it. To switch to mksh, run **cd bin** and **./mksh**.

## Example

Run **mount -t nfs 192.168.1.3:/nfs nfs**.


## Output

Mount the **nfs** directory on the server with IP address of **192.168.1.3** to the newly created **/nfs** directory in the current system.


```
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/
