/home/user # sfdisk -1
sfdisk version 3.08 (aeb@cwi.nl, 040824) from util-linux-2.12r
Usage: sfdisk [options] device ...
device: something like /dev/hda or /dev/sda
useful options:
-s [or --show-size]: list size of a partition
-c [or --id]: print or change partition Id
-l [or --list]: list partitions of each device
-d [or --dump]: idem, but in a format suitable for later input
-i [or --increment]: number cylinders etc. from 1 instead of from 0
-uS, -uB, -uC, -uM: accept/report in units of sectors/blocks/cylinders/MB
-T [or --list-types]:list the known partition types
-D [or --DOS]: for DOS-compatibility: waste a little space
-R [or --re-read]: make kernel reread partition table
-N# : change only the partition with number #
-n : do not actually write to disk
-O file : save the sectors that will be overwritten to file
-I file : restore these sectors again
-v [or --version]: print version
-? [or --help]: print this message
dangerous options:
-g [or --show-geometry]: print the kernel's idea of the geometry
-G [or --show-pt-geometry]: print geometry guessed from the partition table
-x [or --show-extended]: also list extended partitions on output
or expect descriptors for them on input
-L [or --Linux]: do not complain about things irrelevant for Linux
-q [or --quiet]: suppress warning messages
You can override the detected geometry using:
-C# [or --cylinders #]:set the number of cylinders to use
-H# [or --heads #]: set the number of heads to use
-S# [or --sectors #]: set the number of sectors to use
You can disable all consistency checking with:
-f [or --force]: do what I say, even if it is stupid
