       GNU fdisk, lfdisk, gfdisk - manipulate partition tables on a hard drive


       fdisk [options] [device]


       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
       operating systems, and copying data to new hard disks. For  a  list  of
       the  supported  partition  types, see the --list-partition-types option

       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.


       -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

       -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


       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
       table, 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.
