DELPART(8) System Administration DELPART(8)NAME
delpart - simple wrapper around the "del partition" ioctl
SYNOPSIS

This command doesn't manipulate partitions on hard drive.
OPTIONS
device Specify the disk device.
partition
Specify the partition number.

PARTX(8) System Administration PARTX(8)NAME
partx - tell the Linux kernel about the presence and numbering of on-disk partitions
SYNOPSIS
partx [-a|-d|-s|-u] [-t TYPE] [-n M:N] [-] disk
partx [-a|-d|-s|-u] [-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.
The partx 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.
-u, --update
Update the specified partitions.
-g, --noheadings
Do not print a header line.
-h, --help
Print a help text and exit.
-l, --list
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.
-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. This option cannot be combined with --add, --delete or --list options.
-P, --pairs
Output using key="value" format.
-n, --nr M:N
Specify the range of partitions. For backward compatibility also the format M-N is supported. The range may contain negative num-
bers, for example --nr :-1 means the last partition, and --nr -2:-1 means the last two partitions. Supported range specifications
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).
-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.
-v, --verbose
Verbose mode.
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 5 /dev/sdb
Prints the start sector of partition 5 on /dev/sdb 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.
