GNU Parted is a command-line tool used for creating, resizing, and managing partitions on Linux.

Table of Contents

Command	Description
sudo parted -l	List all partitions and disks.
sudo parted /dev/sdX	Start parted for disk /dev/sdX.
sudo parted /dev/sdX print	Show partition table for /dev/sdX.
sudo parted /dev/sdX mklabel gpt	Create a GPT partition table (use msdos for MBR).
sudo parted /dev/sdX unit GB print	Display partitions in GB instead of sectors.
quit	Exit parted.

Start parted on a specific disk

sudo parted /dev/sdX

Create a new partition (Example: 10GB ext4 starting at 1MB)

mkpart primary ext4 1MiB 10GB

Check changes

print

Format the partition (outside parted)

sudo mkfs.ext4 /dev/sdX1

Unmount the partition before resizing

sudo umount /dev/sdX1

Resize the partition (Example: Resize to 20GB)

sudo parted /dev/sdX resizepart 1 20GB

Expand the filesystem (For ext4)

sudo resize2fs /dev/sdX1

List partitions

sudo parted /dev/sdX print

Delete partition #1

sudo parted /dev/sdX rm 1

sudo parted /dev/sdX mklabel gpt

sudo parted /dev/sdX mklabel msdos

Check alignment:

sudo parted /dev/sdX align-check optimal 1

Returns “1 aligned” if aligned correctly.

Command	Description
sudo parted /dev/sdX print free	Show free space on the disk.
sudo parted /dev/sdX set 1 boot on	Mark partition 1 as bootable.
sudo parted /dev/sdX name 1 “MyPartition”	Name partition 1.
sudo parted /dev/sdX rescue 100MB 500MB	Attempt to recover lost partitions.

sudo parted /dev/sdX mklabel gpt
sudo parted /dev/sdX mkpart primary ext4 1MiB 50GB
sudo mkfs.ext4 /dev/sdX1

Now, /dev/sdX1 is a 50GB ext4 partition ready to use!
