# Use `ModifyTargetGroup` with a CLI
<a name="elastic-load-balancing-v2_example_elastic-load-balancing-v2_ModifyTargetGroup_section"></a>

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

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

**AWS CLI**  
**To modify the health check configuration for a target group**  
The following `modify-target-group` example changes the configuration of the health checks used to evaluate the health of the targets for the specified target group. Note that due to the way the CLI parses commas, you must surround the range for the `--matcher` option with single quotes instead of double quotes.  

```
aws elbv2 modify-target-group \
    --target-group-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-https-targets/2453ed029918f21f \
    --health-check-protocol HTTPS \
    --health-check-port 443 \
    --matcher HttpCode='200,299'
```
Output:  

```

    "TargetGroups": [
        {
            "TargetGroupArn": "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-https-targets/2453ed029918f21f",

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example modifes the properties of the specified Target Group.**  

```
Edit-ELB2TargetGroup -TargetGroupArn 'arn:aws:elasticloadbalancing:us-east-1:123456789012:targetgroup/test-tg/a4e04b3688be1970' -HealthCheckIntervalSecond 60 -HealthCheckPath '/index.html' -HealthCheckPort 8080
