PARTED(8) GNU Parted Manual PARTED(8)
NAME
GNU Parted - a partition manipulation program
SYNOPSIS
parted [options] [device [command [options...]...]]
DESCRIPTION
parted is a disk partitioning and partition resizing program. It allows you to create, destroy, resize, move and copy
ext2, linux-swap, FAT, FAT32, and reiserfs partitions. It can create, resize, and move Macintosh HFS partitions, as well
as detect jfs, ntfs, ufs, and xfs partitions. 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;
see near the bottom.
OPTIONS
-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 aligment 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.
COMMANDS
[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:
check partition
Do a simple check on partition.
cp [source-device] source dest
Copy the source partition's filesystem on source-device (or the current device if no other device was spec-
ified) to the dest partition on the current device.
help [command]
Print general help, or help on command if specified.
mkfs partition fs-type
Make a filesystem fs-type on partition. fs-type can be one of "fat16", "fat32", "ext2", "linux-swap", or
"reiserfs".
mklabel label-type
Create a new disklabel (partition table) of label-type. label-type should be one of "bsd", "dvh", "gpt",
"loop", "mac", "msdos", "pc98", or "sun".
mkpart part-type [fs-type] start end
Make a part-type partition with filesystem fs-type (if specified), beginning at start and ending at end (by
default in megabytes). fs-type can be one of "fat16", "fat32", "ext2", "HFS", "linux-swap", "NTFS", "reis-
erfs", or "ufs". part-type should be one of "primary", "logical", or "extended".
mkpartfs part-type fs-type start end
Make a part-type partition with filesystem fs-type beginning at start and ending at end (by default in
megabytes). Using this command is discouraged. Instead use mkpart to create an empty partition, and then
use external tools like mke2fs(8) to create the filesystem.
move partition start end
Move partition so that it begins at start and ends at end. Note: move never changes the minor number.
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.
resize partition start end
Resize the filesystem on partition so that it begins at start and ends at end (by default in megabytes).
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", 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",
"GB", "TB", "%" (percentage of device size), "cyl" (cylinders), "chs" (cylinders, heads, sectors), or "com-
pact" (megabytes for input, and a human-friendly form for output).
version
Display version information and a copyright message.
KNOWN ISSUES
ext3 filesystem functionality does not currently work. To manage ext3 type filesystems use tools like resize2fs(8) or
mke2fs(8). Note that the currently supported ext2 filesystem will be deprecated once ext3 support is finalized. Further
note that ext3 support will have limited functionality that is yet to be defined. Use tools like resize2fs(8) and
mke2fs(8) to manage these types of filesystems.
To manually resize an ext3 filesystem and/or a partition use resize2fs(8), fdisk(8) or similar tools. For LVM situa-
tions, you will need to use the LVM commands to resize the LVM elements.
