PARTX(8) System Manager's Manual PARTX(8)
NAME
partx - tell the Linux kernel about the presence and numbering of on-disk partitions
SYNOPSIS
partx [-a|-d|-s] [-t TYPE] [-n M:N] [-] disk
partx [-a|-d|-s] [-t TYPE] partition [disk]
DESCRIPTION
Given a device or disk-image, partx tries to parse the partition table and list its contents. It optionally adds or removes partitions.
The disk argument is optional when a partition argument is provided. To force scanning a partition as if it were a whole disk (for example
to list nested subpartitions), use the argument "-". For example:
partx --show - /dev/sda3
This will see sda3 as a whole-disk rather than a partition.
This is not an fdisk program -- adding and removing partitions does not change the disk, it just tells the kernel about the presence and
numbering of on-disk partitions.
OPTIONS
-a, --add
Add the specified partitions, or read the disk and add all partitions.
-b, --bytes
Print the SIZE column in bytes rather than in human-readable format.
-d, --delete
Delete the specified partitions or all partitions.
-g, --noheadings
Do not print a header line.
-l, --list
List the partitions. Note that all numbers are in 512-byte sectors. This output format is DEPRECATED in favour of --show. Don't
use it in newly written scripts.
-o, --output list
Define the output columns to use for --show and --raw output. If no output arrangement is specified, then a default set is used.
Use --help to get list of all supported columns.
-r, --raw
Use the raw output format.
-s, --show
List the partitions. All numbers (except SIZE) are in 512-byte sectors. The output columns can be rearranged with the --output
option.
-t, --type type
Specify the partition table type -- aix, bsd, dos, gpt, mac, minix, sgi, solaris_x86, sun, ultrix or unixware.
-n, --nr M:N
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" means the last partition, and "--nr -2:-1" means the last two partitions. Supported range specifi-
cations are:
<M> Specifies just one partition (e.g. --nr 3).
<M:> Specifies lower limit only (e.g. --nr 2:).
<:N> Specifies upper limit only (e.g. --nr :4).
<M:N> or <M-N> Specifies lower and upper limits (e.g. --nr 2:4).
EXAMPLES
partx --show /dev/sdb3
partx --show --nr 3 /dev/sdb
partx --show /dev/sdb3 /dev/sdb
All three commands list partition 3 of /dev/sdb.
partx --show - /dev/sdb3
Lists all subpartitions on /dev/sdb3 (the device is used as whole-disk).
partx -o START -g --nr 3 /dev/sdb
Prints the start sector of partition 5 on /dev/sda without header.
partx -o SECTORS,SIZE /dev/sda5 /dev/sda
Lists the length in sectors and human-readable size of partition 5 on /dev/sda.
partx --add --nr 3:5 /dev/sdd
Adds all available partitions from 3 to 5 (inclusive) on /dev/sdd.
partx -d --nr :-1 /dev/sdd
Removes the last partition on /dev/sdd.
