What is the purpose of the 'partprobe' command?

The 'partprobe' command is designed to inform the operating system kernel about changes made to the partition table. When a partition table is modified, the system might not immediately recognize these changes until it is notified. The 'partprobe' command effectively broadcasts updates to the kernel regarding any alterations in the partition layout, ensuring that the system can accurately reflect these modifications.

This functionality is particularly useful after creating, resizing, or deleting partitions with tools like 'fdisk' or 'parted', as it prompts the system to re-read the partition information without requiring a reboot. In contrast, the other options focus on checking, modifying, or creating partitions, which are different tasks not directly associated with the specific role of 'partprobe'.
