| 28 | =head1 NAME
|
|---|
| 29 |
|
|---|
| 30 | mr-parted2fdisk is a fdisk like command using parted internally for analysing GPT labelled disks
|
|---|
| 31 |
|
|---|
| 32 | =head1 DESCRIPTION
|
|---|
| 33 |
|
|---|
| 34 | mr-parted2fdisk behaves like the fdisk command, but dialog internally with parted in order to manipulate partition tables, which allow it to support GPT partition format as well as MBR, contrary to fdisk. It aims at providing compatible external interface with fdisk. Developed initialy for ia64 Linux, it is also useful now on x86 systems using GPT partition format (for large HDDs).
