dd
It's used to manage images (create / dump)
To dump an image to a device (WARNING, IF YOU ENTER THE WRONG DEVICE IT WILL BE OVERRITEN)
dd bs=4M if="/home/linux/2013-02-09-wheezy-raspbian.img" of=/dev/mmcblk0
To create an image from a CD:
dd if=/dev/cdrom of=/tmp/cdimg1.iso
(*) Note: The cdrom must not be mounted.
You can check the image with md5sum.
To see progres:
dd status=progress if=/dev/cdrom of=/tmp/cdimg1.iso
