GNU cfdisk - a curses-based partition table manipulation program


   cfdisk [options] [device]


   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


   -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.


   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.

          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.


   There are no known bugs. We are in early stages for development, so  be
