wipefs

WIPEFS(8)						       MAINTENANCE COMMANDS							 WIPEFS(8)

NAME

       wipefs - wipe a filesystem signature from a device

SYNOPSIS

       wipefs [-ahnp] [-o offset] device

DESCRIPTION

       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  filesys-
       tems and 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
	      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'.
