.SH NAME
fdisk \- manipulate disk partition table
between logical and physical sector size. This option changes both sector sizes to
.IB sectorsize .
.TP
-\fB\-c\fR, \fB\-\-compatibility\fR[\fI=mode\fR]
+\fB\-B\fR, \fB\-\-protect\-boot\fP
+Don't erase the begin of the first disk sector when create a new disk label. This
+feature is supported for GPT and MBR.
+.TP
+\fB\-c\fR, \fB\-\-compatibility\fR[=\fImode\fR]
Specify the compatibility mode, 'dos' or 'nondos'. The default is non-DOS
mode. For backward compatibility, it is possible to use the option without
the \fImode\fR argument -- then the default is used. Note that the optional
\fB\-h\fR, \fB\-\-help\fR
Display a help text and exit.
.TP
-\fB\-L\fR, \fB\-\-color\fR[\fI=when\fR]
+\fB\-L\fR, \fB\-\-color\fR[=\fIwhen\fR]
Colorize the output. The optional argument \fIwhen\fP
can be \fBauto\fR, \fBnever\fR or \fBalways\fR. If the \fIwhen\fR argument is omitted,
-it defaults to \fBauto\fR. The colors can be disabled, for the current built-in default
-see \fB\-\-help\fR output. See also the COLORS section.
+it defaults to \fBauto\fR. The colors can be disabled; for the current built-in default
+see the \fB\-\-help\fR output. See also the \fBCOLORS\fR section.
.TP
\fB\-l\fR, \fB\-\-list\fR
List the partition tables for the specified devices and then exit.
Enable support only for disklabels of the specified \fItype\fP, and disable
support for all other types.
.TP
-\fB\-u\fR, \fB\-\-units\fR[\fI=unit\fR]
+\fB\-u\fR, \fB\-\-units\fR[=\fIunit\fR]
When listing partition tables, show sizes in 'sectors' or in 'cylinders'. The
default is to show sizes in sectors. For backward compatibility, it is possible
to use the option without the \fIunit\fR argument -- then the default is used.
(Not the physical number, of course, but the number used for
partition tables.) A reasonable value is 63.
+.TP
+\fB\-w\fR, \fB\-\-wipe\fR \fIwhen\fR
+Wipe filesystem, RAID and partition-table signatures from the device, in order
+to avoid possible collisions. The argument \fIwhen\fR can be \fBauto\fR,
+\fBnever\fR or \fBalways\fR. When this option is not given, the default is
+\fBauto\fR, in which case signatures are wiped only when in interactive mode.
+In all cases detected signatures are reported by warning messages
+before a new partition table is created. See also
+.BR wipefs (8)
+command.

+.TP
+\fB\-W\fR, \fB\-\-wipe-partition\fR \fIwhen\fR
+Wipe filesystem, RAID and partition-table signatures from a newly created
+partitions, in order to avoid possible collisions. The argument \fIwhen\fR can
+be \fBauto\fR, \fBnever\fR or \fBalways\fR. When this option is not given, the
+default is \fBauto\fR, in which case signatures are wiped only when in
+interactive mode and after confirmation by user. In all cases detected
+signatures are reported by warning messages before a new partition is
+created. See also
+.BR wipefs (8)
+command.

\fB\-V\fR, \fB\-\-version\fR
Display version information and exit.
