Use GetGroupPolicy with an Amazon SDK or command line tool

To get information about a policy attached to an IAM group

The following get-group-policy command gets information about the specified policy attached to the group named Test-Group.

aws iam get-group-policy \
    --group-name Test-Group \
    --policy-name S3-ReadOnly-Policy

Output:

{
    "GroupName": "Test-Group",
    "PolicyDocument": {
        "Statement": [
            {
                "Action": [
                    "s3:Get*",
                    "s3:List*"
                ],
                "Resource": "*",
                "Effect": "Allow"
            }
        ]
    },
    "PolicyName": "S3-ReadOnly-Policy"
}

Example 1: This example returns details about the embedded inline policy named PowerUserAccess-Testers for the group Testers. The PolicyDocument property is URL encoded. It is decoded in this example with the UrlDecode .NET method.

$results = Get-IAMGroupPolicy -GroupName Testers -PolicyName PowerUserAccess-Testers
$results

Output:

GroupName     PolicyDocument                                              PolicyName
