我是Shell脚本的新手，但是我试图解析命令输出并将这些id值存储为数组。

C:\Users\Shruthi>aws ecs list-tasks --cluster test-cluster --service hello2-service

{
    "taskArns": [
        "arn:aws:ecs:ap-south-1:822063991960:task/6990efe7-4a81-4fe7-8d25-d1ec1898971e","arn:aws:ecs:ap-south-1:822063991960:task/0281508f-4d90-4ebc-afcd-684f58f5405e"
    ]
}

我想将上述taskArns存储到一个数组变量中，

taskArn = (arn:aws:ecs:ap-south-1:822063991960:task/6990efe7-4a81-4fe7-8d25-d1ec1898971e arn:aws:ecs:ap-south-1:822063991960:task/0281508f-4d90-4ebc-afcd-684f58f5405e ..)

等，以便我可以进一步使用此任务ID来描述特定任务并找到其当前状态。

我实现了答案的方法，但是我无法使用$ line变量值进行命令替换，

echo $FOO | while read -r line; do
    name="$line"
    echo "Name read from file - $name"

    #Successfully describes
    val="arn:aws:ecs:ap-southeast-1:296646925901:task/4d2bf627-82f5-45c7-8ad4-60b9e2f1934a"
    aws ecs describe-tasks --cluster mol-dev-cluster --tasks $val

    #Errors out
    aws ecs describe-tasks --cluster mol-dev-cluster --tasks $line
done

导致以下错误
