使用bash脚本在不同列中打印多个不同大小的数组

arr1=("apple" "banana" "cherry")
arr2=("dog" "cat" "elephant" "giraffe")
arr3=("red" "green" "blue" "yellow" "orange")

max_length=0

if [ ${#arr1[@]} -gt $max_length ]; then
    max_length=${#arr1[@]}
fi

if [ ${#arr2[@]} -gt $max_length ]; then
    max_length=${#arr2[@]}
fi

if [ ${#arr3[@]} -gt $max_length ]; then
    max_length=${#arr3[@]}
fi

for ((i=0; i<$max_length; i++)); do
    if [ $i -lt ${#arr1[@]} ]; then
        printf "%-10s" "${arr1[$i]}"
    else
        printf "%-10s" ""
    fi

    if [ $i -lt ${#arr2[@]} ]; then
        printf "%-10s" "${arr2[$i]}"
    else
        printf "%-10s" ""
    fi

    if [ $i -lt ${#arr3[@]} ]; then
        printf "%-10s" "${arr3[$i]}"
    else
        printf "%-10s" ""
    fi

    echo ""
done
