What is the process for creating a file system and mounting it in Linux?

To create a filesystem and mount it in Linux, follow these steps:

1. First, open the terminal and login as the root user.
2. Create a new file system using the following command, such as the ext4 file system:
3. Format the device /dev/sdX with the ext4 file system.
4. /dev/sdX represents the device to create a file system on, such as /dev/sda1.
5. Next, create a directory as a mount point, for example, /mnt/mydisk.
6. Create a directory named “mydisk” in the “mnt” directory.
7. Mount the newly created file system to the mount point using the following command.
8. Attach the device located at /dev/sdX to the directory /mnt/mydisk.
9. /dev/sdX represents the device that needs to be mounted, for example /dev/sda1.
10. If you want the file system to be automatically mounted during system startup, you can edit the /etc/fstab file and add the following line:
11. Mount the ext4 filesystem located at /dev/sdX to /mnt/mydisk with default settings.
12. /dev/sdX represents the device to be mounted, ext4 indicates the file system type, defaults represents the default mounting options, and 0 0 indicates the backup and check order.
13. Finally, use the following command to confirm that the file system has been successfully mounted:
14. show disk space usage in human-readable format
15. This command will display all mounted file systems and their usage.

Please note that the /dev/sdX in the above command should be replaced according to the actual situation to ensure the correct mounting of the file system.
