NAME

       nwipe - securely erase disks

SYNOPSIS

       nwipe [options] [device1] [device2] ...

DESCRIPTION

       nwipe  is  a command that will securely erase disks using a variety of recognised methods.
       It is a fork of the dwipe command used by Darik's Boot and Nuke (dban).  nwipe is included
       with partedmagic if want a quick and easy bootable CD version.  nwipe was created out of a
       need to run the DBAN dwipe command outside of DBAN, in order to allow  its  use  with  any
       host  distribution,  thus  giving  better hardware support.  It is essentially the same as
       dwipe, with a few changes:

       - pthreads is used instead of fork

       - The parted library is used to detect drives

       - The code is designed to be compiled with gcc

       - SIGUSR1 can be used to log the stats of the current wipe
