parted + 使用幫助未描述 resizepart

我們需要在 rhel server 7.2 版本上使用 parted 命令作為範例

parted -s /dev/sda resizepart 2

但是從分開的幫助中我們找不到選項resizepart

例子：

parted -s /dev/sda resizepart 2

使用幫助是否可能或錯誤？

還是真的resizepart不支持？

如果很奇怪，這很好，但要獲得有關分開命令的幫助，設備參數是必須的。

parted [device] help [command]

命令可以是 resizepart、mkpart、print 等。（您可以使用 parted -h 獲取所有命令的列表）

例如parted /dev/sda help resizepart

# parted /dev/sda help resizepart
 resizepart NUMBER END                    resize partition NUMBER

   NUMBER is the partition number used by Linux.  On MS-DOS disk labels, the primary partitions number from 1 to 4, logical partitions from 5 onwards.
       END is disk location, such as 4GB or 10%.  Negative value counts from the end of the disk.  For example, -1s specifies exactly the last sector.
