12 nwipe is a command that will securely erase disks using a variety of
13 recognised methods. It is a fork of the dwipe command used by Darik's
14 Boot and Nuke (dban). nwipe is included with partedmagic if you want a
15 quick and easy bootable CD version. nwipe was created out of a need to
16 run the DBAN dwipe command outside of DBAN, in order to allow its use
17 with any host distribution, thus giving better hardware support. It is
18 essentially the same as dwipe, with a few changes:
19 - pthreads is used instead of fork
21 - The parted library is used to detect drives
23 - The code is designed to be compiled with gcc
25 - SIGUSR1 can be used to log the stats of the current wipe

31 Prints the version number
32 -h, --help

38 wiping all devices immediately. If devices have been specified,
39 starts wiping only those specified devices immediately.
40 --autopoweroff
42 Power off system on completion of wipe delayed for for one
43 minute. During this one minute delay you can abort the shutdown
44 by typing sudo shutdown -c
45 --sync Open devices in sync mode

92 ops2 - RCMP TSSIT OPS-II
94 random / prng / stream - PRNG Stream
96 zero / quick - Overwrite with zeros
98 verify - Verifies disk is zero filled
100 is5enh - HMG IS5 enhanced
102 -l, --logfile=FILE
104 Filename to log to. Default is STDOUT
105 -p, --prng=METHOD
