disk partitions

       partx [-a|-d|-s|-u] [-t TYPE] [-n M:N] [-] disk

       partx [-a|-d|-s|-u] [-t TYPE] partition [disk]

       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  num-
       bering of on-disk partitions.

       -a, --add
              Add  the specified partitions, or read the disk and add all par-

       -b, --bytes
              Print the SIZE column in bytes  rather  than  in  human-readable

       -d, --delete
              Delete the specified partitions or all partitions.

       -u, --update
              Update the specified partitions.

       -g, --noheadings
              Do not print a header line.

       -l, --list
              List the partitions.  Note that all numbers are in 512-byte sec-
              tors.  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
              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" 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

       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

       partx -o START -g --nr 3 /dev/sdb
              Prints the start sector  of  partition  5  on  /dev/sda  without

       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

       partx -d --nr :-1 /dev/sdd
              Removes the last partition on /dev/sdd.
