<a name="iam_example_iam_AttachGroupPolicy_section"></a>

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

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

**AWS CLI**  
**To attach a managed policy to an IAM group**  
The following `attach-group-policy` command attaches the AWS managed policy named `ReadOnlyAccess` to the IAM group named `Finance`.  

```
aws iam attach-group-policy \
    --policy-arn arn:aws:iam::aws:policy/ReadOnlyAccess \
    --group-name Finance
```
This command produces no output.

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example attaches the customer managed policy named `TesterPolicy` to the IAM group `Testers`. The users in that group are immediately affected by the permissions defined in the default version of that policy.**  

```
Register-IAMGroupPolicy -GroupName Testers -PolicyArn arn:aws:iam::123456789012:policy/TesterPolicy
```
**Example 2: This example attaches the AWS managed policy named `AdministratorAccess` to the IAM group `Admins`. The users in that group are immediately affected by the permissions defined in the latest version of that policy.**  

```
Register-IAMGroupPolicy -GroupName Admins -PolicyArn arn:aws:iam::aws:policy/AdministratorAccess
```
+  For API details, see [AttachGroupPolicy](https://docs.aws.amazon.com/powershell/v4/reference) in *AWS Tools for PowerShell Cmdlet Reference (V4)*. 

**Tools for PowerShell V5**  
**Example 1: This example attaches the customer managed policy named `TesterPolicy` to the IAM group `Testers`. The users in that group are immediately affected by the permissions defined in the default version of that policy.**
