GPT fdisk

The utility provides command‑line access to edit GUID Partition Table (GPT) structures on Linux, FreeBSD, macOS and Windows. It can create, delete, resize and rename partitions, as well as convert existing MBR or BSD disklabel layouts to GPT without losing data. An auxiliary tool, FixParts, handles repair of common problems on MBR disks, while the main program can also generate hybrid MBRs or revert GPT to MBR when needed.

It is aimed at system administrators and power users who need direct, scriptable control over disk layouts across multiple operating systems. The tool follows the interface style of the classic fdisk program, offering familiar commands for listing partitions, modifying attributes, and committing changes.

Distinctive capabilities include loss‑less conversion between partition schemes, support for hybrid MBR creation, and built‑in repair functions for damaged GPT or MBR metadata. The software is released under GPL‑2.0 and is considered stable for production use.
