What command is used to manage partitions larger than 2GB?

The command used to manage partitions larger than 2GB is gdisk. This utility is specifically designed for GUID Partition Table (GPT) disks, which are necessary when dealing with large partitions and disks exceeding the 2TB limit inherent to the Master Boot Record (MBR) partitioning scheme.

Unlike fdisk, which is limited to MBR and can only handle partitions up to 2TB and a maximum of four primary partitions, gdisk handles larger disks effectively and supports a greater number of partitions, making it suitable for modern systems that utilize the GPT standard. This is particularly important as many newer systems come with disks much larger than what MBR can manage, necessitating the use of GPT and tools like gdisk.

The other options provided relate to different functionalities: partprobe is used to inform the operating system of partition table changes without requiring a reboot, and swapon -s displays information about active swap space, which does not pertain to partition management in this context. Thus, gdisk is the appropriate choice for managing large partitions effectively.
