#### [ CLI ]

**AWS CLI**  
**更改消息的超时可见性**  
此示例将指定消息的超时可见性更改为 10 小时（10 小时 \$1 60 分钟 \$1 60 秒）。  
命令:  

```
aws sqs change-message-visibility --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --receipt-handle AQEBTpyI...t6HyQg== --visibility-timeout 36000
```
输出：  

```
None.
