Linux is a free and open-source operating system. It was first developed by Linus Torvalds and friends that was first announced on August 25, 1991. The Linux kernel runs on numerous different platforms including the Intel and Alpha platform and is available under the GNU General Public License. The sfdisk works more like fdisk, it prints or manipulates a storage disk partition table. However, sfdisk offers extra features that are not available in fdisk. You can use it just as fdisk, it also supports GPT, MBR, Sun and SGI partition tables. One difference between the two is that sfdisk does not create the standard system partitions for SGI and SUN disk labels like fdisk does.
