====== parted ======

  * [[fdisk]]
  * [[gdisk]]
  * [[grub]]
  * [[grub2]]
  * [[sfdisk]]

Note: from a personal point-of-view, I use ''gdisk'' over ''parted''; ''gdisk'' lets you examine changes more closely, while ''parted'' commands will often not ask for prompts.

Syntax:

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

Options:

  * **-l** - list partition layouts on all block devices
  * **-a** or **--alignment** - set alignment type for newly created partitions
    * **none** - use the minimum amount allowed by the disk type
    * **cylinder** - align partitions to cylinders
    * **minimal** - use minimum alignment as given by the disk topology information
    * **optimal** - use optimum alignment as given by the disk topology information

Commands:

  * **[device]** - block device to use; if none given, uses first block device
  * **[command [options]]**
    * **print** - display the partition table
    * **mkpart** part-type [fs-type] start end - create a new partition of type primary, logical, or extended, beginning at ''start'' and ending at ''end''. Default unit is megabytes.
    * **align-check** type partition - check if partition satisifies the alignment contraint of type
    * **mklabel** lable-type - create a new disklabel / partition table of label-type. fex: bsd, gpt, msdos
    * **name** partition name - set the name of partition to name - supported by GPT, but not MBR
    * **resizepart** start end - set the end position of partition -- this does not modify the filesystem on the partition
    * **rm** partition - delete the partition
    * **select** device - choose device as the current one to edit
    * **set** partition flag state - set the flag on a partition: boot, root, swap, hidden, raid, lvm, legacy_boot, etc. State should be either 'on' or 'off'.
    * **unit** unit - set unit as the display type; fex: 's' for sectors, 'B' for bytes, 'kB', 'MB', 'GB', 'TB', '%' of device size
    * **toggle** partition flag - toggle the state of flag on a partition

Display the partition table of ''/dev/sdc'':

<code>
parted /dev/sdc print
</code>

Create a new, empty partition table on a device with GPT. **Note that this will remove all existing partitions.**

<code>
parted /dev/sdc mklabel gpt
</code>

** Sample walkthrough **

Final format: 1 MB boot partition used by GRUB, a 128 MB partition for the kernel and GRUB2 cnofig, mounted by OS as ''/boot'', a 2 GB swap partition, and the remaining space for the root partition, mounted at ''/''.

Wipe the partition table, create a 2MB primary partition used by GRUB2 (not /boot), starting at the 1st MB and ending at the 2nd, name it ''grub'', and set the ''bios_grub'' label on:

<code>
parted /dev/sdc mklabel gpt
parted /dev/sdc mkpart primary 1 3 unit MB name 1 grub set 1 bios_grub on
parted /dev/sdc mkpart primary 3 131 name 2 boot
parted /dev/sdc mkpart primary 131 2179 name 3 swap
</code>
