for creating, destroying, resizing, checking and copying hard drive
partitions, and the file systems on them.

@section Overview

Hard disks can be divided into logical disks called @i{partitions}
(or @i{disk slices} in the BSD world), which are described in a @i{partition table}, 
which is also called a @i{disklabel}.

For ordinary use, like file storage or operation system installation, you
will most likely need at least one partition, although with most modern operating system,
you might also want to create several partitions, including one for swap space. For example,
you usually create a seperate partition for home directories. For more information on what
partitions you need for your operating system, look at its installation manual.

@b{GNU cfdisk} is a menu-driven program for creating and editing partition tables. It has support
for DOS and MAC type partition tables, BSD and SUN type disklabels and others.

If you don't specify the device of the disk, cfdisk tries to look for devices and opens the first
device available. On most GNU/Linux distributions @i{device} is usually one of the following:

@c ---------------------------------------------------------------------
@display
@c ---------------------------------------------------------------------
@quotation
/dev/hda
/dev/hdb
/dev/sda
/dev/sdb

@end quotation
@end display

IDE disks are usually using /dev/hd[a-h] for device names, SCSI disks - /dev/sd[a-p]. The partitions will
take the device name followed by the partition number, e.g. /dev/hda1. If you are using a GNU/Linux
operating system, you can see @i{/usr/src/linux/Documentation/devices.txt} for more infomation on
device naming.

A DOS type partition table can have up to four `primary' partitions, which get numbers 1-4. One of the 
primary partitions may be used as an `extended' partition, which is used as a container for more partitions,
which are called `logical' and take numbers starting from 5.

A BSD/SUN type disklabel can hold up to 8 partitions, and an IRIX/SGI type disk label, called `dvh'
in cfdisk can hold up to 16.

@node Options

@section Options

@table @code
@item @b{@minus{}h, @minus{}@minus{}help}
Displays a help message.

@item @b{@minus{}v, @minus{}@minus{}version}
Displays the program's version.

@item @b{@minus{}a, @minus{}@minus{}arrow-cursor}
Use an arrow cursor, instead of reverse video highlighting, in 
case your terminal doesn't support it.

@item @b{@minus{}z, @minus{}@minus{}new-table}
Create a new partition table on the disk. This is useful if  you
want  to  change the partition table type or want to repartition
you entire drive. Note that this does not delete the  old  table
on the disk until you commit the changes.


@item @b{@minus{}u, @minus{}@minus{}units=}@i{UNIT}
Sets the default display units to @i{UNIT}. A list of possible units
is given below.

@item @b{@minus{}t, @minus{}@minus{}list-partition-types}
Displays a list of supported partition types and features.
