Display Linux Partition Table with fdisk Command

 

   The partition table on Linux can be display using the fdisk command.  The fdisk command (or partition table manipulator command) can be use to make partition table on your hard disk... the command example below, show how to use the fdisk command to display list of partition table on Fedora Linux system.

fdisk Command Example:

# fdisk -l 

# fdisk -l /dev/sda

# fdisk 

 

1.  Output from fdisk command with -l option display partition table on the system:

[root@fedora ~]# fdisk -l

 

Disk /dev/sda: 10.7 GB,bytes

255 heads, 63 sectors/track, 1305 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x00011e25

 

Device Boot Start End Blocks Id System

/dev/sda1 * 1 25 200781 83 Linux

/dev/sda2 260 8e Linux LVM

 

Disk /dev/dm-0: 9898 MB,bytes

255 heads, 63 sectors/track, 1203 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x00000000

 

Disk /dev/dm-0 doesn't contain a valid partition table

 

Disk /dev/dm-1: 570 MB, 570425344 bytes

255 heads, 63 sectors/track, 69 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x30307800

 

Disk /dev/dm-1 doesn't contain a valid partition table

[root@fedora ~]#

 

2.  Display partition table for first hard disk

[root@fedora ~]# fdisk -l /dev/sda

 

Disk /dev/sda: 10.7 GB,bytes

255 heads, 63 sectors/track, 1305 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Disk identifier: 0x00011e25

 

Device Boot Start End Blocks Id System

/dev/sda1 * 1 25 200781 83 Linux

/dev/sda2 260 8e Linux LVM

[root@fedora ~]#

 

3.  fdisk command without any option display the fdisk command usage:

[root@fedora ~]# fdisk

 

Usage: fdisk [-l] [-b SSZ] [-u] device

E.g.: fdisk /dev/hda (for the first IDE disk)

or: fdisk /dev/sdc (for the third SCSI disk)

or: fdisk /dev/eda (for the first PS/2 ESDI drive)

or: fdisk /dev/rd/c0d0 or: fdisk /dev/ida/c0d0 (for RAID devices)

[root@fedora ~]#
