#### [ CLI ]
**AWS CLI**
**描述附件**
以下 `describe-attachment` 示例返回有关带指定 ID 的附件的信息。
```
aws support describe-attachment \
--attachment-id "attachment-KBnjRNrePd9D6Jx0-Mm00xZuDEaL2JAj_0-gJv9qqDooTipsz3V1Nb19rCfkZneeQeDPgp8X1iVJyHH7UuhZDdNeqGoduZsPrAhyMakqlc60-iJjL5HqyYGiT1FG8EXAMPLE"
```
输出：
```
{
"attachment": {
"fileName": "troubleshoot-screenshot.png",
"data": "base64-blob"
}
}
```
