查看当前分区
cxq@ubuntu:~$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sda5
通过gparted软件将扩展的20G分了7.32G给/dev/sda3
通过ls /dev/sd* 可以发现多了刚刚分配的 /dev/sda3
cxq@ubuntu:~$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sda5
fdisk 将能够打开 /dev/sda3 并允许用户进行分区操作
cxq@ubuntu:~$ sudo fdisk /dev/sda3

Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
The old ext4 signature will be removed by a write command.
Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x0021fe8e.
Command (m for help): m
Help:
DOS (MBR)
a toggle a bootable flag
b edit nested BSD disklabel
c toggle the dos compatibility flag
Generic
d delete a partition
F list free unpartitioned space
l list known partition types
n add a new partition
p print the partition table
t change a partition type
v verify the partition table
i print information about a partition
Misc
m print this menu
u change display/entry units
x extra functionality (experts only)
Script
I load disk layout from sfdisk script file
O dump disk layout to sfdisk script file
Save & Exit
w write table to disk and exit
q quit without saving changes
Create a new label
g create a new empty GPT partition table
G create a new empty SGI (IRIX) partition table
o create a new empty DOS partition table
s create a new empty Sun partition table
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1

Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-15351807, default 15351807): +5G
Created a new partition 1 of type 'Linux' and of size 5 GiB.
