WIPEFS(8) System Administration WIPEFS(8)NAMEwipefs - wipe a filesystem signature from a device
SYNOPSISwipefs [-ahnpV] [-o offset] device
DESCRIPTIONwipefs 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.
