fdisk

fdisk - the general name of system utilities for managing hard disk partitions . Widespread and available in almost any operating system, but they work in different ways. Use a text user interface .

Use on Linux

On Linux, you can run fdisk interactively or in command mode. At startup, you must specify the disk device, for example: / dev / hdb, / dev / sda, etc. In some cases (when changing the partition in command mode), you will need to specify the disk partition (for example / dev / hda1).

Command Mode

fdisk -v Version Output

fdisk [-b SSZ] [-u ] DISK Change partition table

fdisk -l [-b SSZ] [-u] DISK List partition table (s)

fdisk -s PARTITION Give partition size (s) in blocks

-u: give Start and End in sector (instead of cylinder) units

-b 2048: (for certain MO disks) use 2048-byte sectors

Interactive Mode

If at startup you specify only the name of the drive, fdisk starts interactively.

Using fdisk in scripts

This command emulates the user's work:

  fdisk / dev / hda << EOF
 n
 p
 one



 a
 one
 t
 c
 w
 Eof

Fdisk commands: n - create a new partition

p - the new partition will be "primary" (primary) (you can enter "e" - extended (extended))

1 - the primary partition will be the first of four possible (for USB-ZIP must be 4th)

a - make the partition active 1 - make the first section active

t - change the type of the partition с - change the type of the partition to Fat32 (LBA)

w - write changes to disk and exit fdisk
