NAME
GNU fdisk, lfdisk, gfdisk - manipulate partition tables on a hard drive SYNOPSIS
fdisk [options] [device] DESCRIPTION
fdisk is a disk partition manipulation program, which allows you to create, destroy, resize, move and copy partitions on a hard drive using a menu-driven interface. It is useful for organising the disk space on a new drive, reorganising an old drive, creating space for new oper- ating systems, and copying data to new hard disks. For a list of the supported partition types, see the --list-partition-types option below. It comes in two variants, gfdisk and lfdisk. Lfdisk aims to resemble Linux fdisk 2.12, while gfdisk supports more advanced disk operations, like resizing the filesystem, moving and copying partitions. When starting fdisk, the default is to run gfdisk. OPTIONS
-h, --help displays a help message. -v, --version displays the program's version. -L, --linux-fdisk turns on Linux fdisk compatibility mode. This is the same as running lfdisk. -G, --gnu-fdisk turns off Linux fdisk compatibility mode. -i, --interactive where necessary, prompts for user intervention. -p, --script never prompts for user intervention. -l, --list lists the partition table on the specified device and exits. If there is no device specified, lists the partition tables on all detected devices. -r, --raw-list displays a hex dump of the partition table of the disk, similar to the way Linux fdisk displays the raw data in the partition table. -u, --sector-units use sectors, instead of cylinders for a default unit. -s, --size=DEVICE prints the size of the partition on DEVICE is printed on the standard output. -t, --list-partition-types displays a list of supported partition types and features. The following options are available only to lfdisk. -b, --sector-size=SIZE Specify the sector size of the disk. Valid values are 512, 1024 and 2048. Should be used only on older kernels, which don't guess the correct sector size. -C, --cylinders=CYLINDERS Specify the number of cylinders of the disk. Currently does nothing, it is left for Linux fdisk compatibility. -H, --heads=HEADS Specify the number of heads of the disk. Reasonable values are 255 or 16. -S, --sectors=SECTORS Specify the number of sectors per track. A reasonable value is 63. BUGS
Before editing a BSD disklabel, the partition with the disklabel should already exist on the disk and be detected by the OS. If you have created a BSD-type partition, you need to write the changes to the disk. If fdisk fails to notify the OS about the changes in partition ta- ble, you need to restart your computer. As fdisk tries to guess the device holding the BSD disklabel, it might fail to edit it at all, even if the OS has detected it. In this case you are adviced to simply open the device with fdisk directly. It is possible that it doesn't work on some operating systems. Getting the size of a partition with -s might fail, if fdisk fails to guess the disk device, for the same reasons as with the previous bug. SEE ALSO

NAME
GNU cfdisk - a curses-based partition table manipulation program SYNOPSIS
cfdisk [options] [device] DESCRIPTION
cfdisk is a disk partition manipulation program, which allows you to create, destroy, resize, move and copy partitions on a hard drive using a simple menu-driven interface. It is useful for organising the disk space on a new drive, reorganising an old drive, creating space for new operating systems, and copying data to new hard disks. For a list of the supported partition types, see the --list-partition-types option below. OPTIONS
-h, --help displays a help message. -v, --version displays the program's version. -a, --arrow-cursor use an arrow cursor, instead of reverse video highlighting, in case your terminal doesn't support it. -z, --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. -u, --units=UNIT sets the default display units to UNIT. A list of possible units is given below. -t, --list-partition-types displays a list of supported partition types and features. UNITS
You can choose in what unit cfdisk should display quantities like partition sizes. You can choose from sectors, percents, bytes, kilobytes, etc. Note that one kilobyte is equal to 1,000 bytes, as this is consistent with the SI prefixes and is used by hard disk manufacturers. If you prefer to see the sizes in units with binary prefixes, you should instead select one kilo binary byte (kibibyte), which is equal to 1,024 bytes. Whatever display unit you have chosen, you can always enter the quantities in the unit of your choice, for example 1000000B or 1000kB. compact display each size in the most suitable unit from B, kB, MB, GB and TB. B one byte kB one kilobyte (1,000 bytes) MB one megabyte (1,000,000 bytes) GB one gigabyte (1,000,000,000 bytes) TB one terabyte (1,000,000,000,000 bytes) KiB one kilo binary byte (1,024 bytes) MiB one mega binary byte (1,048,576 bytes) GiB one giga binary byte (1,073,741,824 bytes) TiB one tera binary byte (1,099,511,627,776 bytes) s one sector. It depends on the sector size of the disk. You can use it if you want to see or choose the exact size in sectors. % one percent from the size of the disk cyl one cylinder. It depends on the cylinder size. chs use CHS display units. BUGS
There are no known bugs. We are in early stages for development, so be careful. SEE ALSO
