GNU Parted - a partition manipulation program
parted [options] [device [command [options...]...]]
parted is a program to manipulate disk partitions. It
supports multiple partition table formats, including MS-DOS and GPT. It is
useful for creating space for new operating systems, reorganising disk
usage, and copying data to new hard disks.
This manual page documents parted briefly. Complete
documentation is distributed with the package in GNU Info format.
- -h, --help
- displays a help message
- -l, --list
- lists partition layout on all block devices
- -m, --machine
- displays machine parseable output
- -s, --script
- never prompts for user intervention
- -v, --version
- displays the version
- -a alignment-type, --align
alignment-type
- Set alignment for newly created partitions, valid alignment types
are:
- none
- Use the minimum alignment allowed by the disk type.
- cylinder
- Align partitions to cylinders.
- minimal
- Use minimum alignment as given by the disk topology information. This and
the opt value will use layout information provided by the disk to align
the logical partition table addresses to actual physical blocks on the
disks. The min value is the minimum alignment needed to align the
partition properly to physical blocks, which avoids performance
degradation.
- optimal
- Use optimum alignment as given by the disk topology information. This
aligns to a multiple of the physical block size in a way that guarantees
optimal performance.
- [device]
- The block device to be used. When none is given, parted will use
the first block device it finds.
- [command [options]]
- Specifies the command to be executed. If no command is given,
parted will present a command prompt. Possible commands are:
- help
[command]
- Print general help, or help on command if specified.
- align-check
type partition
- Check if partition satisfies the alignment constraint of
type. type must be "minimal" or
"optimal".
- mklabel
label-type
- Create a new disklabel (partition table) of label-type.
label-type should be one of "aix", "amiga",
"bsd", "dvh", "gpt", "loop",
"mac", "msdos", "pc98", or
"sun".
- mkpart part-type
[fs-type] start end
- Make a part-type partition for filesystem fs-type (if
specified), beginning at start and ending at end (by default
in megabytes). part-type should be one of "primary",
"logical", or "extended".
- name partition
name
- Set the name of partition to name. This option works only on
Mac, PC98, and GPT disklabels. The name can be placed in quotes, if
necessary.
- print
- Display the partition table.
- quit
- Exit from parted.
- rescue start
end
- Rescue a lost partition that was located somewhere between start
and end. If a partition is found, parted will ask if you
want to create an entry for it in the partition table.
- resizepart
partition end
- Change the end position of partition. Note that this does
not modify any filesystem present in the partition.
- rm
partition
- Delete partition.
- select
device
- Choose device as the current device to edit. device should
usually be a Linux hard disk device, but it can be a partition, software
raid device, or an LVM logical volume if necessary.
- set partition
flag state
- Change the state of the flag on partition to state.
Supported flags are: "boot", "root", "swap",
"hidden", "raid", "lvm", "lba",
"legacy_boot", "irst", "esp" and
"palo". state should be either "on" or
"off".
- unit
unit
- Set unit as the unit to use when displaying locations and sizes,
and for interpreting those given by the user when not suffixed with an
explicit unit. unit can be one of "s" (sectors),
"B" (bytes), "kB", "MB", "MiB",
"GB", "GiB", "TB", "TiB",
"%" (percentage of device size), "cyl" (cylinders),
"chs" (cylinders, heads, sectors), or "compact"
(megabytes for input, and a human-friendly form for output).
- toggle partition
flag
- Toggle the state of flag on partition.
- version
- Display version information and a copyright message.
