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.
availability
The wipefs command is part of the util-linux package and is
available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
