In Linux system, hard disk formatting is an important operation. By formatting the hard drive, we can clear the data on the hard drive and assign it a file system to facilitate data storage and use. Below, we will introduce in detail how to format the hard disk in Linux system and provide some common code examples.

1. View hard disk information:
   Before formatting the hard disk, we first need to confirm the device name of the hard disk. Run the following command to view the hard disk information of the current system:

sudo fdisk -l

Through the above command, we can get the device name of the hard disk (for example: /dev/sda).

2. Uninstall the hard disk:
   Before formatting the hard disk, you need to ensure that the hard disk is not mounted. If the hard disk is currently being mounted, you can use the following command to uninstall:

sudo umount /dev/sda

3. Format the hard disk:
   Formatting the hard disk can be completed using a variety of commands, commonly used ones are mkfs, fdisk, parted, etc. The following uses the mkfs command as an example to explain how to format a hard disk.

sudo mkfs.ext4 /dev/sda

The ext4 in the above command indicates the file system type we want to use, and /dev/sda is the name of the hard disk device to be formatted. After executing the above command, the system will format the hard disk and assign the ext4 file system.

4. Mount the hard disk:
   After completing the hard disk formatting, we need to mount it to the system for easy use. First, create a directory for mounting:

sudo mkdir /mnt/mydisk

Next, use the following command to mount the hard disk to the specified directory:

sudo mount /dev/sda /mnt/mydisk

Now, the hard disk is successfully mounted to /mnt/mydisk directory. We can read and write files in this directory.

5. Set automatic mounting:
   If you want to automatically mount the hard disk when the system starts, you can do so by editing the /etc/fstab file. Open the file and add the following line at the end:

/dev/sda    /mnt/mydisk    ext4    defaults    0    0

After saving and closing the file, the hard disk will be automatically mounted to the /mnt/mydisk directory after the system is restarted.

Summary:

This article introduces the steps to format the hard disk under Linux system, and provides some commonly used code examples. Through the guidance of this article, you can easily format the hard disk and flexibly manage and utilize the hard disk space. Hope this article is helpful to you.
