Provides control over DOS partition maps on disk devices in Darwin x86 systems. Much of its functionality is devoted to managing an Apple UFS partition that Darwin uses as a boot volume. There can be only one Apple UFS partition on a disk.

When invoked without a device name argument, fdisk enters interactive mode, in which navigation is performed via a series of menus.
