interactive text interface.
a physical disk such as /dev/hda, not a
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.
