Erase free disk space from the command line
Wouldn't you be much better off using /dev/random instead?

Erase free disk space from the command line
Yes, I remember when I setup a FreeBSD server ~5 years ago, I got the standard generating key message you would normally get, then something odd telling me to "wiggle my mouse or hit keys on the keyboard". You feel like an idiot standing at a console in the server room, "wiggling the mouse", and banging on the keyboard, with other admins* walking around asking you if you have gone insane.
Yes, it it!
Firstly one does not run this as root. run this as a normal user. The system reserves some space for the root user, and this way you will not run out of disk space for critical system. (At least I know this to be true for reiser, ext3 and ext2 filesystems on Linux.
Yes, it it!
I would think that this could be equally useful using /dev/random or /dev/zero. ramdom would help obscure old data from disk searches. zero would allow for the raw partition to be more easily compressed.
