<a name="eventbridge_example_eventbridge_ListRules_section"></a>

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

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:

#### [ CLI ]

**AWS CLI**  
**To display a list of all CloudWatch Events rules**  
This example displays all CloudWatch Events rules in the region:  

```
aws events list-rules
```
**To display a list of CloudWatch Events rules beginning with a certain string.**  
This example displays all CloudWatch Events rules in the region that have a name starting with "Daily":  

```
aws events list-rules --name-prefix "Daily"
```
