.SH NAME

nwipe \- securely erase disks
|

.SH SYNOPSIS
|
|
.B nwipe
|
|
[\fIoptions\fR] [\fIdevice1\fR] [\fIdevice2\fR] ...
|
|
.SH 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 you 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:
|
|
.TP
|
|
- pthreads is used instead of fork
|
|
.TP
|
|
- The parted library is used to detect drives
|
|
.TP
|
|
- The code is designed to be compiled with gcc
|
|
.TP
|
|
- SIGUSR1 can be used to log the stats of the current wipe
|
