+.RB [ \-t " \fItype\fR]"
+.IR partition " [" disk ]
+.SH DESCRIPTION
+Given a device or disk-image,
+.B 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.
+.PP
+The
+.I disk
+argument is optional when a
+.I 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:
+
+.RS 7
+.TP
+partx \-\-show \- /dev/sda3
+.RE
+.PP
+This will see sda3 as a whole-disk rather than as a partition.
+.PP
+.B partx is not an fdisk program
+\(en 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
+.TP
+.BR \-a , " \-\-add"
+Add the specified partitions, or read the disk and add all partitions.
+.TP
+.BR \-b , " \-\-bytes"
+Print the SIZE column in bytes rather than in human-readable format.
+.TP
+.BR \-d , " \-\-delete"
+Delete the specified partitions or all partitions.
+.TP
+.BR \-g , " \-\-noheadings"
+Do not print a header line with \fB\-\-show\fR or \fB\-\-raw\fR.
+.TP
+.BR \-l , " \-\-list"
+List the partitions.  Note that all numbers are in 512-byte sectors.
+This output format is DEPRECATED in favour of
+.BR \-\-show .
+Do not use it in newly written scripts.
+.TP
+.BR \-n , " \-\-nr " \fIM : \fIN
+Specify the range of partitions.  For backward compatibility also the
+format \fIM\fB\-\fIN\fR is supported.
+The range may contain negative numbers, for example
+.B \-\-nr \-1:\-1
+means the last partition, and
+.B \-\-nr \-2:\-1
+means the last two partitions.  Supported range specifications are:
+.RS 14
+.TP
+.I M
+Specifies just one partition (e.g.\& \fB\-\-nr 3\fR).
+.TP
+.IB M :
+Specifies the lower limit only (e.g.\& \fB\-\-nr 2:\fR).
+.TP
+.BI : N
+Specifies the upper limit only (e.g.\& \fB\-\-nr :4\fR).
+.TP
+.IB M : N
+Specifies the lower and upper limits (e.g.\& \fB\-\-nr 2:4\fR).
+.RE
+.TP
+.BR \-o , " \-\-output " \fIlist
+Define the output columns to use for
+.BR \-\-show ,
+.B \-\-pairs
+and
+.B \-\-raw
+output.  If no output arrangement is specified, then a default set is
+used.  Use
+.B \-\-help
+to get
+.I list
+of all supported columns.  This option cannot be combined with the
+.BR \-\-add ,
+.BR \-\-delete ,
+.B \-\-update
+or
+.B \-\-list
+options.
+.TP
+.B \-\-output\-all
+Output all available columns.
+.TP
+.BR \-P , " \-\-pairs"
+List the partitions using the KEY="value" format.
+.TP
+.BR \-r , " \-\-raw"
+List the partitions using the raw output format.
+.TP
+.BR \-s , " \-\-show"
+List the partitions.
+The output columns can be selected and rearranged with the
+\fB\-\-output\fR option.
+All numbers (except SIZE) are in 512-byte sectors.
+.TP
+.BR \-t , " \-\-type " \fItype
+Specify the partition table type.
+.TP
+.B \-\-list\-types
+List supported partition types and exit.
+.TP
+.BR \-u , " \-\-update"
+Update the specified partitions.
+.TP
+.BR \-S , " \-\-sector\-size " \fIsize
+Overwrite default sector size.
+.TP
+.BR \-v , " \-\-verbose"
+Verbose mode.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.SH EXAMPLES
+.TP
+partx \-\-show /dev/sdb3
+.TQ
+partx \-\-show \-\-nr 3 /dev/sdb
+.TQ
+partx \-\-show /dev/sdb3 /dev/sdb
+All three commands list partition 3 of /dev/sdb.
+.TP
+partx \-\-show \- /dev/sdb3
+Lists all subpartitions on /dev/sdb3 (the device is used as
+whole-disk).
+.TP
+partx \-o START \-g \-\-nr 5 /dev/sdb
+Prints the start sector of partition 5 on /dev/sdb without header.
+.TP
+partx \-o SECTORS,SIZE /dev/sda5 /dev/sda
+Lists the length in sectors and human-readable size of partition 5 on
+/dev/sda.
+.TP
+partx \-\-add \-\-nr 3:5 /dev/sdd
+Adds all available partitions from 3 to 5 (inclusive) on /dev/sdd.
+.TP
+partx \-d \-\-nr :\-1 /dev/sdd
+Removes the last partition on /dev/sdd.
