#### [ CLI ]

**AWS CLI**  
**To retrieve the version-specific settings of a Lambda function**  
The following `get-function-configuration` example displays the settings for version 2 of the `my-function` function.  

```
aws lambda get-function-configuration \
    --function-name  my-function:2
```
Output:  

```
