NAME
parted - a partition manipulation program

SYNOPSIS
parted [options] [device [command [options...]...]]

DESCRIPTION
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.

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 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.

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 com‐
mands 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.

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" 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.
