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

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

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 enable all actions for an alarm**  
The following example uses the `enable-alarm-actions` command to enable all actions for the alarm named myalarm.:  

```
aws cloudwatch enable-alarm-actions --alarm-names myalarm
```
This command returns to the prompt if successful.
