NAME
       zerofill	- clear	unused disk space and blank devices.

SYNOPSIS
       zerofill	[options] [devices] ...

DESCRIPTION
       This  command is	a relative of nullfile.	 Like nullfile,	it can be used
       to write	all unused disk	space with '0',	thereby	 making	 file  systems
       that are	stored on virtual machines easier to pack.  In addition, zero-
       fill can	fill unused disk space with random data	before zeroing,	 which
       can  be useful to remove	forensic trace of deleted files.  Finally, ze-
       rofile can be told to operate on	and zero  (erase)  complete  disk  de-
       vices.

OPTIONS
       --random=count
	      Number of	passes to use writing random data before wiping	data.

       --help Outputs help screen for the user.
