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 filesystems 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.
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'.
