NAME
       wipefs - wipe a filesystem signature from a device

SYNOPSIS
       wipefs [-ahnpV] [-o offset] device

DESCRIPTION
       wipefs can erase filesystem or raid signatures (magic strings) from the
       specified device to make the filesystem invisible for libblkid.	wipefs
       does  not  erase	 the  filesystem  itself  nor  any other data from the
       device.	When used without options -a  or  -o,  it  lists  all  visible
       filesystems and the offsets of their signatures.

OPTIONS
       -a, --all
	      Erase all available signatures.

       -h, --help
	      Print help and exit.

       -n, --no-act
	      Causes everything to be done except for the write() call.

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

	      The offset argument may be followed  by  binary  (2^N)  suffixes
	      KiB,  MiB, GiB, TiB, PiB and EiB (the "iB" is optional, e.g. "K"
	      has the same meaning as "KiB") or decimal	 (10^N)	 suffixes  KB,
	      MB, GB, PB and EB.

       -p, --parsable
	      Print  out  in parsable instead of printable format.  Encode all
	      potentially unsafe characters of a string to  the	 corresponding
	      hex value prefixed by '\x'.

       -V, --version
	      Output version information and exit.
