#### [ CLI ]

**AWS CLI**  
**To attach a permissions policy to an IAM role**  
The following `put-role-policy` command adds a permissions policy to the role named `Test-Role`.  

```
aws iam put-role-policy \
    --role-name Test-Role \
    --policy-name ExamplePolicy \
    --policy-document file://AdminPolicy.json
```
This command produces no output.  
The policy is defined as a JSON document in the *AdminPolicy.json* file. (The file name and extension do not have significance.)  
To attach a trust policy to a role, use the `update-assume-role-policy` command.  
For more information, see [Modifying a role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_manage_modify.html) in the *AWS IAM User Guide*.

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example creates an inline policy named `FedTesterRolePolicy` and embeds it in the IAM role `FedTesterRole`. If an inline policy with the same name already exists, then it is overwritten. The JSON policy content comes from the file `FedTesterPolicy.json`. Note that you must use the `-Raw` parameter to successfully process the content of the JSON file.**  

```
Write-IAMRolePolicy -RoleName FedTesterRole -PolicyName FedTesterRolePolicy -PolicyDocument (Get-Content -Raw FedTesterPolicy.json)
```
