# Use `DescribeTimeToLive` with an AWS SDK or CLI
<a name="example_dynamodb_DescribeTimeToLive_section"></a>

The following code examples show how to use `DescribeTimeToLive`.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example: 
+  [Work with Streams and Time-to-Live](example_dynamodb_Scenario_StreamsAndTTL_section.md) 

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

**AWS CLI**  
**To view Time to Live settings for a table**  
The following `describe-time-to-live` example displays Time to Live settings for the `MusicCollection` table.  

```
aws dynamodb describe-time-to-live \
    --table-name MusicCollection
```
Output:  

```
{
    "TimeToLiveDescription": {
        "TimeToLiveStatus": "ENABLED",
        "AttributeName": "ttl"
    }
}
```
For more information, see [Time to Live](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/TTL.html) in the *Amazon DynamoDB Developer Guide*.  
+  For API details, see [DescribeTimeToLive](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/dynamodb/describe-time-to-live.html) in *AWS CLI Command Reference*.
