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 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).

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.
