       wipefs - wipe a filesystem signature from a device


       wipefs [-ahnp] [-o offset] device


       wipefs  allows  to  erase filesystem or raid signatures (magic strings)
       from the device to make the filesystem invisible for libblkid.   wipefs
       does  not erase the whole filesystem or any other data from the device.
       When used without options -a or -o, it lists  all  visible  filesystems
       and offsets of their signatures.


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

       -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’.
