Sfdisk

skdisk is a command line utility to partition hard disks. Important because it can operate in a non-interactive way taking commands from STDIN. It can also produce output about the current state of the partitions on a device. With a little scripting it can be made to do the complex and confusing job of disk paritioning in preparation for installation of Peerix.

Examples

root@turing:~/peerix# sfdisk -l /dev/hda

Disk /dev/hda: 77545 cylinders, 16 heads, 63 sectors/track
Warning: extended partition does not start at a cylinder boundary.
DOS and Linux will interpret the contents differently.
Warning: The partition table looks like it was made
  for C/H/S=*/255/63 (instead of 77545/16/63).
For this listing I'll assume that geometry.
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
