.SH DESCRIPTION
Given a device or disk-image,
.B partx
tries to parse the partition table and list its contents. It
-optionally adds or removes partitions.
+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 "-". For example:
+(for example to list nested subpartitions), use the argument "\-" (hyphen-minus).
+For example:
.RS 7

partx \-\-show \- /dev/sda3

.SH OPTIONS
-.IP "\fB\-a\fR, \fB\-\-add\fP"
+.TP
+.BR \-a , " \-\-add"
Add the specified partitions, or read the disk and add all partitions.
-.IP "\fB\-b\fR, \fB\-\-bytes\fP"
+.TP
+.BR \-b , " \-\-bytes"
Print the SIZE column in bytes rather than in human-readable format.
-.IP "\fB\-d\fR, \fB\-\-delete\fP"
-Delete the specified partitions or all partitions.
-.IP "\fB\-u\fR, \fB\-\-update\fP"
-Update the specified partitions.
-.IP "\fB\-g\fR, \fB\-\-noheadings\fP"
-Do not print a header line.
-.IP "\fB\-h\fR, \fB\-\-help\fP"
-Display help text and exit.
-.IP "\fB\-l\fR, \fB\-\-list\fP"
+.TP
+.BR \-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 \fB\-\-nr\fR ranges without care about the current partitions set on
+the device.
+.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.
-.IP "\fB\-o\fR, \fB\-\-output \fIlist\fP"
+.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
-.B \-\-show
+.BR \-\-show ,
+.B \-\-pairs
and
.B \-\-raw
output. If no output arrangement is specified, then a default set is
.B \-\-help
to get
.I list
-of all supported columns. This option cannot be combined with

.BR \-\-add ,
-.B \-\-delete
+.BR \-\-delete ,

or
.B \-\-list
options.
-.IP "\fB\-P\fR, \fB\-\-pairs\fP"
-Output using key="value" format.
-.IP "\fB\-n\fR, \fB\-\-nr \fIM:N\fP"
-Specify the range of partitions. For backward compatibility also the

-.I M-N
-is supported. The range may contain negative numbers, for example
-.BI \-\-nr \ :\-1
-means the last partition, and
-.BI \-\-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\fR
