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. +.SH SEE ALSO +.BR addpart (8), +.BR delpart (8), +.BR fdisk (8), +.BR parted (8), +.BR partprobe (8) +.SH AUTHORS +.MT dave@gnu.org +Davidlohr Bueso +.ME +.br +.MT kzak@redhat.com +Karel Zak +.ME +.PP +The original version was written by +.MT aeb@cwi.nl +Andries E.\& Brouwer +.ME . +.SH ENVIRONMENT +.IP LIBBLKID_DEBUG=all +enables libblkid debug output. +.SH AVAILABILITY +The partx command is part of the util-linux package and is available from +.UR https://\:www.kernel.org\:/pub\:/linux\:/utils\:/util-linux/ +Linux Kernel Archive +.UE . -- cgit v1.2.3
