-b | --sector-size | size | Specify the sector size (512, 1024, 2048 or 4096) of the disk. Only or old kernels (or to force a size) since recent kernels know the sector size. |
-B | --protect-boot | | Don't erase the beginning of the first disk sector when creating a new disk label (GPT and MBR). |
-c | --compatibility | [=mode] | Specify the compatibility mode (dos or nondos, the latter being the default). |
-L | --color | [=when] | Colored output. The optional when can be auto (default), never or always. |
-l | --list | | List the partition tables for the specified devices and then exit. If no devices are given, those mentioned in /proc/partitions (if it exists) are used. |
-x | --list-details | | Like --list, but showing more details. |
| | --lock[=mode] | | Use exclusive BSD lock for device or file it operates. |
-n | --noauto-pt | | Don't automatically create a default partition table on empty device. (The partition table has to be explicitly created using commands such as o, g, etc.). |
-o | --output | list | Specify which output columns to print. The default list of columns may be extended if list is specified in the format +list (e.g., -o +UUID). |
-s | --getsz | | Print the size in 512-byte sectors of each given block device. Deprectated in favor of blockdev. |
-t | --type | type | Enable support only for disklabels of the specified type, and disable support for all other types. |
-u | --units | [=unit] | When listing partition tables, show sizes in sectors (default) or in cylinders. |
-C | --cylinders | N | Specify the number of cylinders of the disk. Usefulnes of this option is very dubious. |
-H | --heads | N | Specify the number of heads of the disk. (Not the physical number, of course, but the number used for partition tables.) Reasonable values are 255 and 16. |
-S | --sectors | N | Specify the number of sectors per track of the disk. (Not the physical number, of course, but the number used for partition tables.) A reasonable value is 63. |
-w | --wipe | when | Wipe filesystem, RAID and partition-table signatures from the device, in order to avoid possible collisions. The argument when can be auto (default), never or always. See also wipefs |
-W | --wipe-partitions | when | like --wipe, but for newly created partitions. |
-V | --version | | |
-h | --help | | |
