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

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

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:

    /// <param name="ruleName">The name of the rule.</param>
    /// <param name="eventBusName">The optional name of the event bus. If empty, uses the default event bus.</param>
    /// <returns>The state of the rule.</returns>

#### [ CLI ]

**AWS CLI**  
**To display information about a CloudWatch Events rule**  
This example displays information about the rule named DailyLambdaFunction:  

```
aws events describe-rule --name "DailyLambdaFunction"
