list-object-versions¶

Description¶

Returns metadata about all of the versions of objects in a bucket. You can also use request parameters as selection criteria to return metadata about a subset of all the object versions.

Note

A 200 OK response can contain valid or invalid XML. Make sure to design your application to parse the contents of the response and handle it appropriately.

To use this operation, you must have READ access to the bucket.

The following operations are related to ListObjectVersions :

ListObjectsV2
GetObject
PutObject
DeleteObject

Synopsis¶

  list-object-versions
--bucket <value>
[--delimiter <value>]
[--encoding-type <value>]
[--prefix <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--bucket (string)

The bucket name that contains the objects.

When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this operation using an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide .

--delimiter (string)

A delimiter is a character that you specify to group keys. All keys that contain the same string between the prefix and the first occurrence of the delimiter are grouped under a single result element in CommonPrefixes. These groups are counted as one result against the max-keys limitation. These keys are not returned elsewhere in the response.

--encoding-type (string)

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.

Possible values:

url

--prefix (string)

Use this parameter to select only those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys. (You can think of using prefix to make groups in the same way you’d use a folder in a file system.) You can use prefix with delimiter to roll up numerous objects into a single result under CommonPrefixes.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples¶

The following command retrieves version information for an object in a bucket named my-bucket:

aws s3api list-object-versions --bucket my-bucket --prefix index.html

Output¶

IsTruncated -> (boolean)

A flag that indicates whether Amazon S3 returned all of the results that satisfied the search criteria. If your results were truncated, you can make a follow-up paginated request using the NextKeyMarker and NextVersionIdMarker response parameters as a starting place in another request to return the rest of the results.

KeyMarker -> (string)

Marks the last key returned in a truncated response.

VersionIdMarker -> (string)

Marks the last version of the key returned in a truncated response.

NextKeyMarker -> (string)

When the number of responses exceeds the value of MaxKeys , NextKeyMarker specifies the first key not returned that satisfies the search criteria. Use this value for the key-marker request parameter in a subsequent request.

NextVersionIdMarker -> (string)

When the number of responses exceeds the value of MaxKeys , NextVersionIdMarker specifies the first object version not returned that satisfies the search criteria. Use this value for the version-id-marker request parameter in a subsequent request.

Versions -> (list)

Container for version information.

(structure)

The version of an object.

ETag -> (string)

The entity tag is an MD5 hash of that version of the object.

Size -> (integer)

Size in bytes of the object.

StorageClass -> (string)

The class of storage used to store the object.

Key -> (string)

The object key.

VersionId -> (string)

Version ID of an object.

IsLatest -> (boolean)

Specifies whether the object is (true) or is not (false) the latest version of an object.

LastModified -> (timestamp)

Date and time the object was last modified.

Owner -> (structure)

Specifies the owner of the object.

DisplayName -> (string)

Container for the display name of the owner.

ID -> (string)

Container for the ID of the owner.

DeleteMarkers -> (list)

Container for an object that is a delete marker.

(structure)

Information about the delete marker.

Owner -> (structure)

The account that created the delete marker.>

DisplayName -> (string)

Container for the display name of the owner.

ID -> (string)

Container for the ID of the owner.

Key -> (string)

The object key.

VersionId -> (string)

Version ID of an object.

IsLatest -> (boolean)

Specifies whether the object is (true) or is not (false) the latest version of an object.

LastModified -> (timestamp)

Date and time the object was last modified.

Name -> (string)

Bucket name.

Prefix -> (string)

Selects objects that start with the value supplied by this parameter.

Delimiter -> (string)

The delimiter grouping the included keys. A delimiter is a character that you specify to group keys. All keys that contain the same string between the prefix and the first occurrence of the delimiter are grouped under a single result element in CommonPrefixes . These groups are counted as one result against the max-keys limitation. These keys are not returned elsewhere in the response.

MaxKeys -> (integer)

Specifies the maximum number of objects to return.

CommonPrefixes -> (list)

All of the keys rolled up into a common prefix count as a single return when calculating the number of returns.

(structure)

Container for all (if there are any) keys between Prefix and the next occurrence of the string specified by a delimiter. CommonPrefixes lists keys that act like subdirectories in the directory specified by Prefix. For example, if the prefix is notes/ and the delimiter is a slash (/) as in notes/summer/july, the common prefix is notes/summer/.

Prefix -> (string)

Container for the specified common prefix.

EncodingType -> (string)

Encoding type used by Amazon S3 to encode object key names in the XML response.

If you specify encoding-type request parameter, Amazon S3 includes this element in the response, and returns encoded key name values in the following response elements:

KeyMarker, NextKeyMarker, Prefix, Key , and Delimiter .
