Manipulate or display the partition table for
device using a command-driven
interactive text interface.

partition such as /dev/hda1. If omitted,
device defaults to
/dev/hda. Interactive commands to
fdisk are a single letter followed by a
carriage return. The commands do not take arguments, but instead
start an interactive dialog. Commands that operate on a
partition will request the partition number, which is an
integer. For primary and extended partitions, the partition
number is from 1 to 4. For logical partitions, which are
available only when the extended partition already exists to
contain them, the partition number is from 5 to 16.
When making changes to the partition table, fdisk accumulates changes without writing them to the disk, until it receives the write command.
Toggle the bootable flag on/off for a primary partition.
Delete a partition. You are prompted for the partition number to delete. If you delete a logical partition when higher-numbered logical partitions exist, the partition numbers are decremented to keep logical partition numbers contiguous.
List the known partition types. A table of partition types is printed.
Display the brief help menu for these commands.
Add a new partition. You are prompted for the partition type (primary, extended, or logical). For primary and extended partitions, you are asked for the partition number (1–4). For logical ...
