#20 Low Level Data Copying with dd
If you need to copy data, byte for byte, you use dd. dd can do many great things like copying a hard disk to another disk, making .iso's of CDs or DVDs, and making backup images of data.
Further, dd can zero out a drive, create files with random data, dig into your memory, make backup of your master boot record, bench test your disks... the list goes on.
In this episode we'll just scratch the surface by making copies of our hard disk, restoring that hard disk with the image, and making .iso's from a CD.

Most Linux/Unix users are familiar with Grep, but for many situations Ack does a better and faster job.
