Create an ISO image of a CD or DVD in GNU/Linux

Very simple, without using auxiliary programs and from our console.

The first thing we do is make sure the CD/DVD is not mounted automatically in our system. This means that if unit appears as we manually remove it, either by using the umount command in fstab or disabling the CD/DVD is mounted automatically when you insert a disc. For convenience, I raised the first option:
  • $ sudo umount /media/mounted_unit_name
Now comes the easy part. Using the dd command define the input device (the CD, DVD or Blu-Ray) and the output, which in this case is the ISO image. Thus:
  • $ dd if=/dev/dvd of=imagen_del_dvd.iso
And presto, a simple recipe for a task does not require specific software.
