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 operating 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 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.
