NAME <\/a> <\/h2>\n

partx \u2212 tell the kernel about the presence and numbering of on-disk partitions<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

partx<\/b> [\u2212a<\/b>|\u2212d<\/b>|\u2212P<\/b>|\u2212r<\/b>|\u2212s<\/b>|\u2212u<\/b>] [\u2212t<\/b> type<\/i>] [\u2212n<\/b> M<\/i>:<\/b>N<\/i>] [\u2212<\/b>] disk<\/i>
partx<\/b> [\u2212a<\/b>|\u2212d<\/b>|\u2212P<\/b>|\u2212r<\/b>|\u2212s<\/b>|\u2212u<\/b>] [\u2212t<\/b> type<\/i>] partition<\/i> [disk<\/i>]<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

Given a device or disk-image, partx<\/b> tries to parse the partition table and list its contents. It can also tell the kernel to add or remove partitions from its bookkeeping.<\/p>\n

The disk<\/i> argument is optional when a partition<\/i> argument is provided. To force scanning a partition as if it were a whole disk (for example to list nested subpartitions), use the argument “\u2212” (hyphen-minus). For example:<\/p>\n

partx \u2212\u2212show \u2212 \/dev\/sda3<\/p>\n

This will see sda3 as a whole-disk rather than as a partition.<\/p>\n

partx is not an fdisk program<\/b> \u2013 adding and removing partitions does not change the disk, it just tells the kernel about the presence and numbering of on-disk partitions.<\/p>\n

OPTIONS <\/a> <\/h2>\n

\u2212a<\/b>, \u2212\u2212add<\/b><\/p>\n

Add the specified partitions, or read the disk and add all partitions.<\/p>\n

\u2212b<\/b>, \u2212\u2212bytes<\/b><\/p>\n

Print the SIZE column in bytes rather than in human-readable format.<\/p>\n

\u2212d<\/b>, \u2212\u2212delete<\/b><\/p>\n

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 \u2212\u2212nr<\/b> ranges without care about the current partitions set on the device.<\/p>\n

\u2212g<\/b>, \u2212\u2212noheadings<\/b><\/p>\n

Do not print a header line with \u2212\u2212show<\/b> or \u2212\u2212raw<\/b>.<\/p>\n

\u2212l<\/b>, \u2212\u2212list<\/b><\/p>\n

List the partitions. Note that all numbers are in 512-byte sectors. This output format is DEPRECATED in favour of \u2212\u2212show<\/b>. Do not use it in newly written scripts.<\/p>\n

\u2212n<\/b>, \u2212\u2212nr<\/b> M<\/i>:<\/b>N<\/i><\/p>\n

Specify the range of partitions. For backward compatibility also the format M<\/i>\u2212<\/b>N<\/i> is supported. The range may contain negative numbers, for example \u2212\u2212nr \u22121:\u22121<\/b> means the last partition, and \u2212\u2212nr \u22122:\u22121<\/b> means the last two partitions. Supported range specifications are:<\/p>\n\n\n\n\n\n
<\/td>\n\n

M<\/i><\/p>\n<\/td>\n

<\/td>\n\n

Specifies just one partition (e.g. \u2212\u2212nr 3<\/b>).<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

M<\/i>:<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Specifies the lower limit only (e.g. \u2212\u2212nr 2:<\/b>).<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

:<\/b>N<\/i><\/p>\n<\/td>\n

<\/td>\n\n

Specifies the upper limit only (e.g. \u2212\u2212nr :4<\/b>).<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

M<\/i>:<\/b>N<\/i><\/p>\n<\/td>\n

<\/td>\n\n

Specifies the lower and upper limits (e.g. \u2212\u2212nr 2:4<\/b>).<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

\u2212o<\/b>, \u2212\u2212output<\/b> list<\/i><\/p>\n

Define the output columns to use for \u2212\u2212show<\/b>, \u2212\u2212pairs<\/b> and \u2212\u2212raw<\/b> output. If no output arrangement is specified, then a default set is used. Use \u2212\u2212help<\/b> to get list<\/i> of all supported columns. This option cannot be combined with the \u2212\u2212add<\/b>, \u2212\u2212delete<\/b>, \u2212\u2212update<\/b> or \u2212\u2212list<\/b> options.<\/p>\n

\u2212\u2212output\u2212all<\/b><\/p>\n

Output all available columns.<\/p>\n

\u2212P<\/b>, \u2212\u2212pairs<\/b><\/p>\n

List the partitions using the KEY=”value” format.<\/p>\n

\u2212r<\/b>, \u2212\u2212raw<\/b><\/p>\n

List the partitions using the raw output format.<\/p>\n

\u2212s<\/b>, \u2212\u2212show<\/b><\/p>\n

List the partitions. The output columns can be selected and rearranged with the \u2212\u2212output<\/b> option. All numbers (except SIZE) are in 512-byte sectors.<\/p>\n

\u2212t<\/b>, \u2212\u2212type<\/b> type<\/i><\/p>\n

Specify the partition table type.<\/p>\n

\u2212\u2212list\u2212types<\/b><\/p>\n

List supported partition types and exit.<\/p>\n

\u2212u<\/b>, \u2212\u2212update<\/b><\/p>\n

\u2212S<\/b>, \u2212\u2212sector\u2212size<\/b> size<\/i><\/p>\n

Overwrite default sector size.<\/p>\n

\u2212v<\/b>, \u2212\u2212verbose<\/b><\/p>\n
