sudo gdisk -l
Example
sudo gdisk /dev/sdX
说明
gdisk is an interactive GPT (GUID Partition Table) partitioning tool, similar to fdisk but designed specifically for GPT disks. It can create, delete, and modify partitions on modern UEFI systems. GPT is the modern partitioning scheme that replaces MBR (Master Boot Record), supporting disks larger than 2TB and more than 4 primary partitions (up to 128). gdisk maintains both primary and backup partition tables for redundancy. gdisk can also convert MBR disks to GPT (and vice versa with sgdisk), though this should be done carefully with backups.
参数
- -l, --list
- List partition tables for all devices and exit
- device
- Device to partition (e.g., /dev/sda, /dev/nvme0n1)
