Copy a DVD and transfer it to another machine, all in one go
Use case: I have an old laptop with a CD/DVD drive and my current laptop, which does not have such ancient devices. I want to rip the DVD and put the result onto the other laptop immediately. It’s not that hard. Just do:
dd if=/dev/sr0 | ssh nik@192.168.178.77 "dd of=/media/nik/media/video/sledge_hammer/dvd_1.iso"
Note the quotation around the args for the SSH (the second dd).[1] For this, of course, an SSH server has to run on the target.
I found the basic idea for this command here: https://www.thegeekdiary.com/how-to-clone-linux-disk-partition-over-network-using-dd/.

Although this sounds like an utterly smart idea ("Whoa, I’m piping to another machine. I must be l33t".), it is not if you have a slow network/wifi. I stopped ripping a disk after half a day, because the job was still not done. If you are on lame wifi, you’re better off using a USB stick or so to transfer the data. |
