Use ListPolicies with an AWS SDK or command line tool

The following code examples show how to use ListPolicies.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

To list managed policies that are available to your AWS account

This example returns a collection of the first two managed policies available in the current AWS account.

aws iam list-policies \ --max-items 3

Output:

Example 1: This example returns a collection of the first three managed policies available in the current AWS account. Because -scope is not specified, it defaults to all and includes both AWS managed and customer managed policies.

Get-IAMPolicyList -MaxItem 3

Output:

Arn : arn:aws:iam::aws:policy/AWSDirectConnectReadOnlyAccess AttachmentCount : 0 CreateDate : 2/6/2015 10:40:08 AM DefaultVersionId : v1 Description : IsAttachable : True Path : / PolicyId : Z27SI6FQMGNQ2EXAMPLE1 PolicyName : AWSDirectConnectReadOnlyAccess UpdateDate : 2/6/2015 10:40:08 AM Arn : arn:aws:iam::aws:policy/AmazonGlacierReadOnlyAccess AttachmentCount : 0 CreateDate : 2/6/2015 10:40:27 AM DefaultVersionId : v1 Description : IsAttachable : True Path : / PolicyId : NJKMU274MET4EEXAMPLE2 PolicyName : AmazonGlacierReadOnlyAccess UpdateDate : 2/6/2015 10:40:27 AM Arn : arn:aws:iam::aws:policy/AWSMarketplaceFullAccess AttachmentCount : 0 CreateDate : 2/11/2015 9:21:45 AM DefaultVersionId : v1 Description : IsAttachable : True Path : / PolicyId : 5ULJSO2FYVPYGEXAMPLE3 PolicyName : AWSMarketplaceFullAccess UpdateDate : 2/11/2015 9:21:45 AM

Example 2: This example returns a collection of the first two customer managed policies available in current AWS account. It uses -Scope local to limit the output to only customer managed policies.

Get-IAMPolicyList -Scope local -MaxItem 2

Output:

Arn : arn:aws:iam::123456789012:policy/MyLocalPolicy AttachmentCount : 0 CreateDate : 2/12/2015 9:39:09 AM DefaultVersionId : v2 Description : IsAttachable : True Path : / PolicyId : SQVCBLC4VAOUCEXAMPLE4 PolicyName : MyLocalPolicy UpdateDate : 2/12/2015 9:39:53 AM Arn : arn:aws:iam::123456789012:policy/policyforec2instancerole AttachmentCount : 1 CreateDate : 2/17/2015 2:51:38 PM DefaultVersionId : v11 Description : IsAttachable : True Path : / PolicyId : X5JPBLJH2Z2SOEXAMPLE5 PolicyName : policyforec2instancerole UpdateDate : 2/18/2015 8:52:31 AM
