下面的aws命令输出下面的json，我想从其中提取具有字符串“vm-managed-itg* values”的资源（输出中的最后两个条目）
$aws资源组标记api获取资源--资源类型过滤器云监视：警报--配置文件访问|jq '.资源标记Map列表[]| select（包含（{标签：[{关键字：“虚拟机：成本：帐户”} ]}）|无）|select（包含（{标签：[{值：“itg”} ]}）|没有）“

{
  "ResourceARN": "arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-uat-test",
  "Tags": []
}
{
  "ResourceARN": "arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-stg-test",
  "Tags": []
}
{
  "ResourceARN": "arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-uat-test3",
  "Tags": []
}
{
  "ResourceARN": "arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-stg-test1",
  "Tags": []
}
{
  "ResourceARN": "arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-itg-test1",
  "Tags": []
}
{
  "ResourceARN": "arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-itg-test",
  "Tags": []
}

我尝试添加jq -r '.[].ResourceARN'，但它不起作用，而是抛出此错误

~$ aws resourcegroupstaggingapi get-resources --resource-type-filters cloudwatch:alarm --profile per-acc --output json | jq '.ResourceTagMappingList[] | select(contains({Tags: [{Key: "vm:cost:accountenv"} ]}) | not) | select(contains({Tags: [{Value: "itg"} ]}) | not)' | jq -r '.[].ResourceARN'

使用select仅返回符合条件的实体。可以使用contains测试子字符串匹配：

select(.ResourceARN|contains("vm-managed-itg"))

输出量：

{
  "ResourceARN": "arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-itg-test1",
  "Tags": []
}
{
  "ResourceARN": "arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-itg-test",
  "Tags": []
}

如果您只对ResourceARN的值感兴趣，而不对标记和周围对象感兴趣，则：

.ResourceARN | select(contains("vm-managed-itg"))

jq将过滤器应用于其输入（对象流）中的每个JSON实体。
输出量：

"arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-itg-test1"
"arn:aws:cloudwatch:us-east-1:xxxx:alarm:vm-managed-itg-test"

（jq -r表示不带引号的原始输出）。
