If you want to wipe out a portion (say the contents of one home directory) - perhaps use shred. apt-get install shred ; shred /home/hmotamedi If you want to nuke the MBR partition table to reinstall an operating system dd if=/dev/zero of=/dev/sda bs=446 count=2 [or hda/hdb/sdb or whatever as appropriate for the particular device] If you want to wipe an entire drive dd if=/dev/urandom of=/dev/sda repeated a couple of times if necessary. Better, by far, is to get hold of a copy of DBAN [floppy image/CD image or even Windows .exe] Runs in memory, uses a Linux kernel to bootstrap a disk wipe program offering various options.] Using this, you can also securely delete hard drives before disposing of a machine / securely remove any pre-existing contents on any drives in a machine you acquire. It _will_ take a long time, almost certainly longer than you think, even if you only do write once with random, once with 1's once with 0's.
