Description

Returns some or all (up to 1,000) of the objects in a bucket. You can use the request parameters as selection criteria to return a subset of the objects in a bucket. A 200 OK response can contain valid or invalid XML. Be sure to design your application to parse the contents of the response and handle it appropriately. This API has been revised. We recommend that you use the newer version, ListObjectsV2, when developing applications. For backward compatibility, Amazon S3 continues to support ListObjects. The following operations are related to ListObjects:

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-BucketName <String>
The name of the bucket containing the objects whose keys are to be listed.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Delimiter <String>
A delimiter is a character you use to group keys.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Encoding <EncodingType>
Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
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)
-Key <String>
Key value identifying a single object in S3 to return metadata for.
Required?True
Position?2
Accept pipeline input?True (ByPropertyName)
-Marker <String>
Specifies the key to start with when listing objects in a bucket.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-Marker $null' for the first call and '-Marker $AWSHistory.LastServiceResponse.NextMarker' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesNextToken
-MaxKey <Int32>
Sets the maximum number of keys returned in the response. The response might contain fewer keys but will never contain more.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxKeys
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of Marker as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the BucketName parameter. The -PassThru parameter is deprecated, use -Select '^BucketName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Prefix <String>
Limits the response to keys that begin with the specified prefix.
Required?False
Position?2
Accept pipeline input?True (ByPropertyName)
AliasesKeyPrefix
-RequestPayer <RequestPayer>
Confirms that the requester knows that she or he will be charged for the list objects request. Bucket owners need not specify this parameter in their requests.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'S3Objects'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.S3.Model.ListObjectsResponse). Specifying the name of a property of type Amazon.S3.Model.ListObjectsResponse 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.

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
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-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.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-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
Position?Named
Accept pipeline input?True (ByPropertyName)
