nwipe — securely erase disks
nwipe [options] [device1] [device2] ...
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:
- 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
- -V, --version
Prints the version number
- -h, --help
Prints a help summary
If no devices have been specified on the command line, starts wiping all devices immediately. If devices have been specified, starts wiping only those specified devices immediately.
