Configure Ubuntu hard disk partitioning and create a file system

Article Title: Configure Ubuntu hard disk partitioning and create a file system. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic categories 1. List disk partition commands
　
Sudo fdisk-l
　
Take my machine configuration as an example:
　
Disk/dev/sda: 160.0 GB, 160041885696 bytes
　
255 heads, 63 sectors/track, 19457 cylinders
　
Units = cylinders of 16065*512 = 8225280 bytes
　
Disk identifier: 0xd3b7d3b7
　
Device Boot Start End Blocks Id System
　
/Dev/sda1*1 2591 20812176 7 HPFS/NTFS
　
/Dev/sda2 2592 17876 122776762 + f W95 Ext 'd (LBA)
　
/Dev/sda3 17877 19457 12699382 + 83 Linux
　
/Dev/sda5 2592 12790 81923436 7 HPFS/NTFS
　
/Dev/sda6 12791 17814 40355248 + 7 HPFS/NTFS
　
/Dev/sda7 17815 17876 497983 + 82 Linux swap/Solaris
　
Hard Disk device name:/dev/sda, size: 160 GB
　
There are six partitions, sda1, sda2, sda3, sda5, sda6, and sda7.
　
2. Create a New partition. fdisk is followed by the hard disk device name.
　
Sudo fdisk/dev/sda
　
Common sub-commands are as follows:
　
P shows the existing Partition
　
N create a partition
　
T disk partition type
　
D. delete a partition.
　
A. Change the partition startup flag.
　
W writes changes to the partition to the hard disk and exits.
　
Q. Do not save the changes and exit
　
3. Create a file system (equivalent to windows format)
　
After creating a partition, you can use
　
Sudo mkfs-t ext3/dev/sda3
　
4. Mount the File System
　
After a file system is created, it must be mounted before use.
　
Sudo mount device name folder name
　
Sudo mount/dev/sda3/home
　
To automatically mount the file system when the system starts, modify the/etc/fstab file.
　
Sudo vi/etc/fstab
　
Add a row in the format required.
　
5. umount File System
　
If you no longer use a file system, you can use the umount command.
　
Sudo umount device name
　
Or sudo umount mount point
