SYNOPSIS

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

parted is a program to manipulate disk partitions. It supports multiple partition table formats, including MS-DOS (MBR) and GPT. It can be used to create space for new operating systems, reorganize disk usage, and copy data to new hard disks.

PARAMETERS

-h, --help

Display help message

-l, --list

List partition layout on all block devices

-m, --machine

Show machine-parseable output

-j, --json

Show JSON output

-s, --script

Never prompt for user intervention

-f, --fix

Auto-answer "fix" to exceptions in script mode

-a, --align TYPE

Set alignment for new partitions (none, cylinder, minimal, optimal)

COMMANDS

mklabel TYPE

Create new partition table (gpt, msdos, etc.)

mkpart NAME START END

Create new partition with optional filesystem type

print

Display partition table

rm NUMBER

Delete partition by number

select DEVICE

Choose device to edit

set NUMBER FLAG STATE

Change partition flags (boot, raid, lvm, esp, etc.)

name NUMBER NAME

Set partition name (GPT only)

resizepart NUMBER END

Modify partition end position

rescue START END

Recover lost partitions

type NUMBER TYPE

Set partition type ID (MBR) or UUID (GPT)

unit UNIT

Set display/input units (s, B, kB, MB, GB, TB, %)

CAVEATS

Parted modifies the partition table directly and changes take effect immediately. Always backup important data before modifying partitions. Use -s flag for scripting to avoid interactive prompts.

HISTORY

parted is part of the GNU Parted package, first released in 1999 by Andrew Clausen. It was designed to handle larger disks and more partition types than traditional fdisk.
