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 numbering of on-disk partitions. + +== OPTIONS + +*-a*, *--add*:: +Add the specified partitions, or read the disk and add all partitions. + +*-b*, *--bytes*:: +include::man-common/in-bytes.adoc[] + +*-d*, *--delete*:: +Delete the specified partitions or all partitions. It is not error to remove non-existing partitions, so this option is possible to use together with large *--nr* ranges without care about the current partitions set on the device. + +*-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 sectors. 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 negative 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. + +*--output-all*:: +Output all available columns. + +*-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. + +include::man-common/help-version.adoc[] + +== ENVIRONMENT + +LIBBLKID_DEBUG=all:: +enables libblkid debug output. + +== EXAMPLE + +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_. + +== AUTHORS + +mailto:dave@gnu.org[Davidlohr Bueso], +mailto:kzak@redhat.com[Karel Zak] + +The original version was written by mailto:aeb@cwi.nl[Andries E.
