# 将 `DescribeAccountAttributes` 与 AWS SDK 或 CLI 配合使用
<a name="example_rds_DescribeAccountAttributes_section"></a>

以下代码示例演示如何使用 `DescribeAccountAttributes`。

------
#### [ CLI ]

**AWS CLI**  
**描述账户属性**  
以下 `describe-account-attributes` 示例将检索当前 AWS 账户的属性。  

```
aws rds describe-account-attributes
```
输出：  

```

    "AccountQuotas": [
        {
            "Max": 40,
