| == 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 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. 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. |
| |
| *-V*, *--version*:: |
| Display version information and exit. |
| |
| *-h*, *--help*:: |
| Display help text and exit. |
| |
| == 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_. |
