    /// List IAM groups.
    /// </summary>
    /// <returns>A list of IAM groups.</returns>
    public async Task<List<Group>> ListGroupsAsync()

#### [ CLI ]

**AWS CLI**  
**To list the IAM groups for the current account**  
The following `list-groups` command lists the IAM groups in the current account.  

```
aws iam list-groups
```
Output:  

```
{
    "Groups": [
        {
            "Path": "/",
            "CreateDate": "2013-06-04T20:27:27.972Z",
