 Force erasure, even if the filesystem is mounted.  This is required in
 order to erase the partition table on a block device.

 Specify the location (in bytes) of the signature which should be erased from the
 device.  The \fIoffset\fR number may include a "0x" prefix; then the number will be
 interpreted as a hex value.  It is possible to specify multiple \fB-o\fR options.
 
 The \fIoffset\fR argument may be followed by the multiplicative
