# The `parted` command
|
||
|
|
|
||
|
|
The `parted` command is used to manage hard disk partitions on Linux. It can be used to add, delete, shrink and extend disk partitions along with the file systems located on them.
|
||
|
|
You will need root access to the system to run `parted` commands.
|
||
|
|
|
||
|
|
**NOTE:** Parted writes the changes immediately to your disk, be careful when you are modifying the disk partitions.
|
||
|
|
### Examples:
|
||
|
|
|
||
|
|
1. Displays partition layout of all block devices:
|
||
|
|
```
|
||
|
|
sudo parted -l
|
||
|
|
```
|
||
|
|
|
||
|
|
2. Display partition table of a specific `disk`
|
||
|
|
```
|
||
|
|
sudo parted disk print
|
||
|
|
```
|
||
|
|
|
||
|
|
Examples of `disk` are /dev/sda, /dev/sdb
|
||
|
|
|
||
|
|
3. Create a new disk label of `label-type` for a specific disk
|
||
|
|
```
|
||
|
|
sudo parted mklabel disk label-type
|
||
|
|
```
|
||
|
|
|
||
|
|
`label-type` can take values "aix", "amiga", "bsd", "dvh", "gpt", "loop", "mac", "msdos", "pc98", or "sun" <br />
|
||
|
|
|
||
|
|
4. Create a new partition in a specific `disk` of type `part-time`, file system is `fs-type` and of size `size` Mb.
|
||
|
|
```
|
||
|
|
sudo parted disk mkpart part-time fs-type 1 size
|
||
|
|
```
|
||
|
|
|
||
|
|
`part-time` can take values "primary", "logical", "extended".<br />
|
||
|
|
`fs-type` is optional. It can take values "btrfs", "ext2", "ext3", "ext4", "fat16", "fat32", "hfs", "hfs+", "linux-swap", "ntfs", "reiserfs", "udf", or "xfs"<br />
|
||
|
|
`size` has to less than the total size of the specified disk. To create a partition of size 50Mb, <size> will take the value of 50
|
||
|
|
|
||
|
|
5. `parted` can also be run in an interactive format. Operations to manage the disk partitions can be performed by entering appropriate commands in the interactive session.
|
||
|
|
`help` command in the interactive session shows a list of all possible disk management operations which can be performed.
|
||
|
|
```
|
||
|
|
$ sudo parted
|
||
|
