Flashing USB with "dd"

dd is a command to convert and copy a file. It is useful to copy information from a disk.

It can be used to create bootable USB.

Let's say that you need to create a 'live' usb to install or repair a GNU-linux system.

An example with parabola:

• First, obtain a ISO image: https://wiki.parabola.nu/Get_Parabola
• Then, open a shell and use the command

  sudo dd if=/home/user/Documents/parabola-2016.11.03-dual.iso of=/dev/sdb1

The ISO image is copied to "sdb1" (USB volume)
