Parted

Last updated:
Reference:wiki.archlinux.org

Usage ​

Replace /dev/sda with the device you wish to partition.

shell
parted /dev/sda

Then you will enter in the command prompt. To reset the partitions, run:

txt
mklabel gpt

Then start creating the partitions. The example bellow creates a swap partition with size of 8GB (size of my memory). Using the free -m command we get the size of the memory in mebibytes (MiB), and sum it with 261MiB.

txt
mkpart "EFI System Partition" fat32 1MiB 261MiB
mkpart "SWAP Partition" linux-swap 261MiB 8135MiB
mkpart "Root Partition" ext4 8135MiB 100%

When using EFI, we need to set the flag esp to its partition.

txt
set 1 esp on

Disk partitioning is done. Type quit to go back to shell.

Partition label ​

Persistent block device naming

If after formatting a partition you want to change the label, use one of the commands bellow depending on the file system:

shell
swaplabel -L newlabel /dev/XXX
e2label /dev/XXX newlabel
fatlabel /dev/XXX newlabel
ntfslabel /dev/XXX newlabel
cryptsetup config --label=newlabel /dev/XXX
