How to rip DVD to ISO on Linux?
Unlike ripping DVD to ISO on Windows with 3rd-party program, Linux allows you to do that by default. Just insert your DVD, open Termina, Enter the change directory command. Type in dvd/home/username/ and then press Enter to the next step. Then, type in dd if=/dev/dvdrom of=/home/username/iso-name.iso DVD ripping command. Finally press Enter to create an ISO file from your DVD in the home directory.
