            ;;
        "Téléchargement de la video")
              read -p "entrer Liens Video ou chemin/nom d'un fichier contenant des liens:" vid

              if [[ -e $vid ]] ; then
                 while read Line
                  do
                    process_video $Line
                  done < $vid 
                 else
                    process_video $vid
              fi 
             break
            ;;
        "Quit")
            break
            ;;
        *) echo invalid option;;
