Burn a CDI (not by me)

burn-cdi.sh

#!/usr/bin/env bash
set -o errexit

cdi_img="$1"
device="${2:-/dev/sr0}"

cdirip "$cdi_img" -cdrecord
i=1

while true; do
    n=$(printf '%02u' "$i")
    iso="tdata${n}.iso"
    wav="taudio${n}.wav"

    if [ -f "$wav" ]; then
        cdrecord "dev=${device}" speed=4 -multi -audio "$wav"
        rm "$wav"
    elif [ -f "$iso" ]; then
        cdrecord "dev=${device}" speed=4 -multi -xa "$iso"
        rm "$iso"
    else
        break
    fi
    
    ((i++))
done
