 to resize existing partitions. It supports both MBR and GPT partitions, but if you start with an empty disk, you may need to explicitly tell it to create GPT data structures to use GPT.
parted -- GParted is based around a library called libparted, and parted is a simpler text-mode tool that uses the same library. Although parted can't resize filesystems and is less user-friendly than GParted, it's still commonly used, particularly when a text-mode tool is preferred. Unlike GParted, parted does not enable creating filesystems in partitions; for that, you use other text-mode tools, like mkfs.
GPT fdisk -- This is a family of text-mode partitioning tools (gdisk, sgdisk, and cgdisk) that I wrote. They're designed exclusively for use on GPT disks, and gdisk, in particular, provides better control of GPT data structures than any other tool of which I'm aware. Unusually, GPT fdisk will automatically convert a disk from MBR to GPT form, which can be handy (but can also lead to trouble if you use it without knowing what you're doing). Like parted, GPT fdisk works on partition table data structures exclusively; you must use mkfs or other tools to create or manipulate filesystems.
fdisk -- This tool and its cousins (sfdisk and cfdisk) originally supported MBR and some other obscure partition table types. It's recently been updated to support GPT; the version delivered with Ubuntu 16.04 supports GPT. Like parted and GPT fdisk, fdisk requires use of other tools to create or manipulate filesystems. Note that the gdisk and cgdisk user interfaces are modeled after those of fdisk and cfdisk, respectively. (I wrote GPT fdisk long before fdisk acquired GPT functionality.)

At this point, I recommend you review your configuration with GParted or GPT fdisk. In particular, you can check the validity of the partition table with sgdisk's -v option, as in:
$ sudo sgdisk -v /dev/sda

No problems found. 6 free sectors (3.0 KiB) available in 1
segments, the largest of which is 6 (3.0 KiB) in size.

This will tell you whether there are any problems with the partition table on /dev/sda (change that

 parted -- GParted is establish around a library called libparted, and parted is a simple text - mode cock that uses the same library. Although parted can't resize filesystems and is less exploiter - friendly than GParted, it's still commonly used, particularly when a text - manner tool is preferred. Unlike GParted, parted does not enable create filesystems in partitions; for that, you use other text - manner tools, like mkfs. 
 GPT fdisk -- This is a family of text - mode partitioning creature (gdisk, sgdisk, and cgdisk) that I wrote. They're designed exclusively for use on GPT disks, and gdisk, in particular, provides better control of GPT data structures than any other tool of which I'm aware. Unusually, GPT fdisk will automatically convert a disk from MBR to GPT kind, which can be handy (but can also lead to worry if you practice it without sleep together what you're doing). Like parted, GPT fdisk works on division table datum structures exclusively; you must use mkfs or early tools to create or manipulate filesystems. 
 fdisk -- This tool and its cousins (sfdisk and cfdisk) originally supported MBR and some early obscure partition table types. It's recently been updated to support GPT; the version hand over with Ubuntu 16.04 corroborate GPT. Like parted and GPT fdisk, fdisk requires use of other creature to create or manipulate filesystems. Note that the gdisk and cgdisk user interface are modeled after those of fdisk and cfdisk, respectively. (I wrote GPT fdisk long before fdisk acquired GPT functionality .) 

 At this point, I commend you review your configuration with GParted or GPT fdisk. In particular, you can check the validity of the partition mesa with sgdisk's -v option, as in: 
 $ sudo sgdisk -v /dev / sda 

 No problem found. 6 complimentary sectors (3.0 kilobyte) available in 1 
 segments, the largest of which is 6 (3.0 KiB) in size.
