NAME
partx - tell the kernel about the presence and numbering of on-disk partitionsSYNOPSIS
partx [-a|-d|-P|-r|-s|-u] [-t type] [-n M:_N_] [-] diskDESCRIPTION
Given a device or disk-image, partx tries to parse the partition table and list its contents. It can also tell the kernel to add or remove partitions from its bookkeeping.OPTIONS
-a, --addAdd the specified partitions, or read the disk
and add all partitions.
Print the sizes in bytes rather than in a
human-readable format.
By default, the unit, sizes are expressed in, is byte, and unit prefixes are in
power of 2^10 (1024). Abbreviations of symbols are exhibited truncated in
order to reach a better readability, by exhibiting alone the first letter of
them; examples: "1 KiB" and "1 MiB" are respectively
exhibited as "1 K" and "1 M", then omitting on purpose the
mention "iB", which is part of these abbreviations.
Delete the specified partitions or all
partitions. It is not error to remove non-existing partitions, so this option
is possible to use together with large --nr ranges without care about
the current partitions set on the device.
Do not print a header line with --show
or --raw.
List the partitions. Note that all numbers are
in 512-byte sectors. This output format is DEPRECATED in favour of
--show. Do not use it in newly written scripts.
Specify the range of partitions. For backward
compatibility also the format M-N is supported. The range
may contain negative numbers, for example --nr -1:-1 means the last
partition, and --nr -2:-1 means the last two partitions. Supported
range specifications are:
M
M:
:N
M:N
Specifies just one partition (e.g. --nr
3).
Specifies the lower limit only (e.g. --nr
2:).
Specifies the upper limit only (e.g. --nr
:4).
Specifies the lower and upper limits (e.g.
--nr 2:4).
Define the output columns to use for
--show, --pairs and --raw output. If no output
arrangement is specified, then a default set is used. Use --help to get
list of all supported columns. This option cannot be combined with the
--add, --delete, --update or --list options.
Output all available columns.
List the partitions using the
KEY="value" format.
List the partitions using the raw output
format.
List the partitions. The output columns can be
selected and rearranged with the --output option. All numbers (except
SIZE) are in 512-byte sectors.
Specify the partition table type.
List supported partition types and exit.
Update the specified partitions.
Overwrite default sector size.
Verbose mode.
Display help text and exit.
Print version and exit.
ENVIRONMENT
LIBBLKID_DEBUG=allenables libblkid debug output.
EXAMPLE
partx --show /dev/sdb3, partx --show --nr 3 /dev/sdb, partx --show /dev/sdb3 /dev/sdbAll three commands list partition 3 of
/dev/sdb.
Lists all subpartitions on /dev/sdb3
(the device is used as whole-disk).
Prints the start sector of partition 5 on
/dev/sdb without header.
Lists the length in sectors and human-readable
size of partition 5 on /dev/sda.
Adds all available partitions from 3 to 5
(inclusive) on /dev/sdd.
Removes the last partition on
/dev/sdd.
