PARTX(8)		     System Administration		      PARTX(8)

NAME
       partx  -	 tell  the  kernel about the presence and numbering of on-disk
       partitions

SYNOPSIS
       partx [-a|-d|-P|-r|-s|-u] [-t type] [-n M:N] [-] disk
       partx [-a|-d|-P|-r|-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 can also tell the kernel to add or remove
       partitions from its bookkeeping.

       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  "-"  (hyphen-minus).
       For example:

	      partx --show - /dev/sda3

       This will see sda3 as a whole-disk rather than as a partition.

       partx is not an fdisk program – adding and removing partitions does not
       change the disk, it just tells the kernel about the presence  and  num‐
       bering of on-disk partitions.

OPTIONS
       -a, --add
	      Add  the specified partitions, or read the disk and add all par‐
	      titions.

       -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 with --show or --raw.

       -l, --list
	      List the partitions.  Note that all numbers are in 512-byte sec‐
	      tors.  This output format is DEPRECATED in favour of --show.  Do
	      not use it in newly written scripts.

       -n, --nr M:N
	      Specify  the  range  of  partitions.  For backward compatibility
	      also the format M-N is supported.	 The range may	contain	 nega‐
	      tive  numbers,  for example --nr -1:-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 the lower limit only (e.g. --nr 2:).

		     :N	    Specifies the upper limit only (e.g. --nr :4).

		     M:N    Specifies  the  lower  and upper limits (e.g. --nr
			    2:4).

       -o, --output list
	      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.

       -P, --pairs
	      List the partitions using the KEY="value" format.

       -r, --raw
	      List the partitions using the raw output format.

       -s, --show
	      List the partitions.  The output columns	can  be	 selected  and
	      rearranged  with the --output option.  All numbers (except SIZE)
	      are in 512-byte sectors.

       -t, --type type
	      Specify the partition table type.

       --list-types
	      List supported partition types and exit.

       -u, --update
	      Update the specified partitions.

       -S, --sector-size size
	      Overwrite default sector size.

       -v, --verbose
	      Verbose mode.

       -V, --version
	      Display version information and exit.

       -h, --help
	      Display help text and exit.

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.
