+.SH "DESCRIPTION"
+.sp
+Given a device or disk\-image, \fBpartx\fP tries to parse the partition table and list its contents. It can also tell the kernel to add or remove partitions from its bookkeeping.
+.sp
+The \fIdisk\fP argument is optional when a \fIpartition\fP 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:
+.RS 3
+.ll -.6i
+.sp
+partx \-\-show \- /dev/sda3
+.br
+.RE
+.ll
+.sp
+This will see sda3 as a whole\-disk rather than as a partition.
+.sp
+\fBpartx is not an fdisk program\fP \- adding and removing partitions does not change the disk, it just tells the kernel about the presence and numbering of on\-disk partitions.
+.SH "OPTIONS"
+.sp
+\fB\-a\fP, \fB\-\-add\fP
+.RS 4
+Add the specified partitions, or read the disk and add all partitions.
+.RE
+.sp
+\fB\-b\fP, \fB\-\-bytes\fP
+.RS 4
+Print the sizes in bytes rather than in a human\-readable format.
+.sp
+By default, the unit, sizes are expressed in, is byte, and unit prefixes are in
+power of 2^10 (1024). Abbreviations of symbols are exhibited truncated in order
+to reach a better readability, by exhibiting alone the first letter of them;
+examples: "1 KiB" and "1 MiB" are respectively exhibited as "1 K" and "1 M",
+then omitting on purpose the mention "iB", which is part of these abbreviations.
+.RE
+.sp
+\fB\-d\fP, \fB\-\-delete\fP
+.RS 4
+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 \fB\-\-nr\fP ranges without care about the current partitions set on the device.
+.RE
+.sp
+\fB\-g\fP, \fB\-\-noheadings\fP
+.RS 4
+Do not print a header line with \fB\-\-show\fP or \fB\-\-raw\fP.
+.RE
+.sp
+\fB\-l\fP, \fB\-\-list\fP
+.RS 4
+List the partitions. Note that all numbers are in 512\-byte sectors. This output format is DEPRECATED in favour of \fB\-\-show\fP. Do not use it in newly written scripts.
+.RE
+.sp
+\fB\-n\fP, \fB\-\-nr\fP \fIM\fP\fB:\fP\fIN\fP
+.RS 4
+Specify the range of partitions. For backward compatibility also the format \fIM\fP\fB\-\fP\fIN\fP is supported. The range may contain negative numbers, for example \fB\-\-nr \-1:\-1\fP means the last partition, and \fB\-\-nr \-2:\-1\fP means the last two partitions. Supported range specifications are:
+.sp
+\fIM\fP
+.RS 4
+Specifies just one partition (e.g. \fB\-\-nr 3\fP).
+.RE
+.sp
+\fIM\fP\fB:\fP
+.RS 4
+Specifies the lower limit only (e.g. \fB\-\-nr 2:\fP).
+.RE
+.sp
+\fB:\fP\fIN\fP
+.RS 4
+Specifies the upper limit only (e.g. \fB\-\-nr :4\fP).
+.RE
+.sp
+\fIM\fP\fB:\fP\fIN\fP
+.RS 4
+Specifies the lower and upper limits (e.g. \fB\-\-nr 2:4\fP).
+.RE
+.RE
+.sp
+\fB\-o\fP, \fB\-\-output\fP \fIlist\fP
+.RS 4
+Define the output columns to use for \fB\-\-show\fP, \fB\-\-pairs\fP and \fB\-\-raw\fP output. If no output arrangement is specified, then a default set is used. Use \fB\-\-help\fP to get \fIlist\fP of all supported columns. This option cannot be combined with the \fB\-\-add\fP, \fB\-\-delete\fP, \fB\-\-update\fP or \fB\-\-list\fP options.
+.RE
+.sp
+\fB\-\-output\-all\fP
+.RS 4
+Output all available columns.
+.RE
+.sp
+\fB\-P\fP, \fB\-\-pairs\fP

+.RE

+\fB\-r\fP, \fB\-\-raw\fP
+.RS 4
+List the partitions using the raw output format.
+.RE
+.sp
+\fB\-s\fP, \fB\-\-show\fP
+.RS 4
+List the partitions. The output columns can be selected and rearranged with the \fB\-\-output\fP option. All numbers (except SIZE) are in 512\-byte sectors.
+.RE
