Description

End of support notice: Beginning November 21, 2025, Amazon S3 will stop returning DisplayName. Update your applications to use canonical IDs (unique identifier for Amazon Web Services accounts), Amazon Web Services account ID (12 digit identifier) or IAM ARNs (full resource naming) as a direct replacement of DisplayName. This change affects the following Amazon Web Services Regions: US East (N. Virginia) Region, US West (N. California) Region, US West (Oregon) Region, Asia Pacific (Singapore) Region, Asia Pacific (Sydney) Region, Asia Pacific (Tokyo) Region, Europe (Ireland) Region, and South America (São Paulo) Region. This operation is not supported for directory buckets. This implementation of the GET action uses the acl subresource to return the access control list (ACL) of a bucket. To use GET to return the ACL of the bucket, you must have the READ_ACP access to the bucket. If READ_ACP permission is granted to the anonymous user, you can return the ACL of the bucket without using an authorization header. When you use this API operation with an access point, provide the alias of the access point in place of the bucket name. When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes. If your bucket uses the bucket owner enforced setting for S3 Object Ownership, requests to read ACLs are still supported and return the bucket-owner-full-control ACL with the owner being the account that created the bucket. For more information, see Controlling object ownership and disabling ACLs in the Amazon S3 User Guide. You must URL encode any signed header values that contain spaces. For example, if your header value is my file.txt, containing two spaces after my, you must URL encode this value to my%20%20file.txt. The following operations are related to GetBucketAcl:

Parameters

-BucketName <String>
Specifies the S3 bucket whose ACL is being requested.When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes.

-ClientConfig <AmazonS3Config>
Amazon.PowerShell.Cmdlets.S3.AmazonS3ClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ExpectedBucketOwner <String>
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ForcePathStyleAddressing <Boolean>
S3 requests can be performed using one of two URI styles: Virtual or Path. When using Virtual style, the bucket is included as part of the hostname. When using Path style the bucket is included as part of the URI path. The default value is $true when the EndpointUrl parameter is specified, $false otherwise.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Grants'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.S3.Model.GetBucketAclResponse). Specifying the name of a property of type Amazon.S3.Model.GetBucketAclResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-UseAccelerateEndpoint <SwitchParameter>
Enables S3 accelerate by sending requests to the accelerate endpoint instead of the regular region endpoint. To use this feature, the bucket name must be DNS compliant and must not contain periods (.).
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-UseDualstackEndpoint <SwitchParameter>
Configures the request to Amazon S3 to use the dualstack endpoint for a region. S3 supports dualstack endpoints which return both IPv6 and IPv4 values. The dualstack mode of Amazon S3 cannot be used with accelerate mode.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False

-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.

-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
