wipefs - wipe a filesystem signature from a device
wipefs [-ahnpV] [-o offset] device
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.
-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, 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.
