device Specify the disk device. partition Specify the partition number. SEE ALSO

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.
