for item1 in "${list1[@]}"
do
    found=0
    for item2 in "${list2[@]}"
    do
        if [[ "$item1" == "$item2" ]]; then
            found=1
            break
        fi
    done
    if [[ $found -eq 1 ]]; then
        echo "$item1 exists in both lists"
    else
        echo "$item1 does not exist in list2"
