Listing IAM user groups - AWS Identity and Access Management
AWSDocumentationAWS Identity and Access ManagementUser Guide


LISTING IAM USER GROUPS

PDFRSS

You can list all the user groups in your account, list the users in a user
group, and list the user groups a user belongs to. If you use the AWS CLI or AWS
API, you can list all the user groups with a particular path prefix.

TO LIST ALL THE USER GROUPS IN YOUR ACCOUNT

Do any of the following:

 * AWS Management Console: In the navigation pane, choose User groups.

 * AWS CLI: aws iam list-groups

 * AWS API: ListGroups

TO LIST THE USERS IN A SPECIFIC USER GROUP

Do any of the following:

 * AWS Management Console: In the navigation pane, choose User groups, choose
   the name of the group, and then choose the Users tab.

 * AWS CLI: aws iam get-group

 * AWS API: GetGroup

TO LIST ALL THE USER GROUPS THAT A USER IS IN

Do any of the following:

 * AWS Management Console: In the navigation pane, choose Users, choose the user
   name, and then choose the Groups tab.

 * AWS CLI: aws iam list-groups-for-user

 * AWS API: ListGroupsForUser
