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 + +.SH OPTIONS +.TP +\fB\-V\fR, \fB\-\-version\fR +Prints the version number +.TP +\fB\-h\fR, \fB\-\-help\fR +Prints a help summary +.TP +\fB\-\-autonuke\fR +If no devices have been specified on the command line, starts wiping all +devices immediately.
