# Use `PutScheduledUpdateGroupAction` with a CLI
<a name="example_auto-scaling_PutScheduledUpdateGroupAction_section"></a>

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

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

**AWS CLI**  
**Example 1: To add a scheduled action to an Auto Scaling group**  
This example adds the specified scheduled action to the specified Auto Scaling group.  

```
aws autoscaling put-scheduled-update-group-action \
    --auto-scaling-group-name my-asg \
    --scheduled-action-name my-scheduled-action \
    --start-time "2023-05-12T08:00:00Z" \
    --min-size 2 \
    --max-size 6 \
    --desired-capacity 4
```
This command produces no output. If a scheduled action with the same name already exists, it will be overwritten by the new scheduled action.  
For more examples, see [Scheduled scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-scheduled-scaling.html) in the *Amazon EC2 Auto Scaling User Guide*.  
**Example 2: To specify a recurring schedule**  
This example creates a scheduled action to scale on a recurring schedule that is scheduled to execute at 00:30 hours on the first of January, June, and December every year.  

```
aws autoscaling put-scheduled-update-group-action \
    --auto-scaling-group-name my-asg \
    --scheduled-action-name my-recurring-action \
    --recurrence "30 0 1 1,6,12 *" \
    --min-size 2 \
    --max-size 6 \
    --desired-capacity 4
```
This command produces no output. If a scheduled action with the same name already exists, it will be overwritten by the new scheduled action.  
For more examples, see [Scheduled scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-scheduled-scaling.html) in the *Amazon EC2 Auto Scaling User Guide*.
