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.
