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.
-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’.
