       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.
