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
