# list-objects-v2

## Description

Returns some or all (up to 1,000) of the objects in a bucket with each request. 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. Make sure to design your application to parse the contents of the response and handle it appropriately. For more information about listing objects, see [Listing object keys programmatically](https://docs.aws.amazon.com/AmazonS3/latest/userguide/ListingKeysUsingAPIs.html) in the *Amazon S3 User Guide* . To get a list of your buckets, see [ListBuckets](https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListBuckets.html) .

#### NOTE
* **General purpose bucket** - For general purpose buckets, `ListObjectsV2` doesn’t return prefixes that are related only to in-progress multipart uploads.
* **Directory buckets** - For directory buckets, `ListObjectsV2` response includes the prefixes that are related only to in-progress multipart uploads.
* **Directory buckets** - For directory buckets, you must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format \`\`[https://](https://)*amzn-s3-demo-bucket* .s3express-*zone-id* .\*region-code\* .amazonaws.com/*key-name* \`\` . Path-style requests are not supported. For more information about endpoints in Availability Zones, see [Regional and Zonal endpoints for directory buckets in Availability Zones](https://docs.aws.amazon.com/AmazonS3/latest/userguide/endpoint-directory-buckets-AZ.html) in the *Amazon S3 User Guide* . For more information about endpoints in Local Zones, see [Concepts for directory buckets in Local Zones](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-lzs-for-directory-buckets.html) in the *Amazon S3 User Guide* .

Permissions

* **General purpose bucket permissions** - To use this operation, you must have READ access to the bucket. You must have permission to perform the `s3:ListBucket` action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see [Permissions Related to Bucket Subresource Operations](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-with-s3-actions.html#using-with-s3-actions-related-to-bucket-subresources) and [Managing Access Permissions to Your Amazon S3 Resources](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-access-control.html) in the *Amazon S3 User Guide* .
* **Directory bucket permissions** - To grant access to this API operation on a directory bucket, we recommend that you use the \` `CreateSession` [https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession).html\`_\_ API operation for session-based authorization. Specifically, you grant the `s3express:CreateSession` permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the `CreateSession` API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another `CreateSession` API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see \` `CreateSession` [https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession).html\`_\_ .

  Sorting order of returned objects
* **General purpose bucket** - For general purpose buckets, `ListObjectsV2` returns objects in lexicographical order based on their key names.
* **Directory bucket** - For directory buckets, `ListObjectsV2` does not return objects in lexicographical order.

  HTTP Host header syntax

> **Directory buckets** - The HTTP Host header syntax is \`\` *Bucket-name* .s3express-*zone-id* .\*region-code\* .amazonaws.com\`\` .

#### WARNING
This section describes the latest revision of this action. We recommend that you use this revised API operation for application development. For backward compatibility, Amazon S3 continues to support the prior version of this API operation, [ListObjects](https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjects.html) .

The following operations are related to `ListObjectsV2` :

* [GetObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html)
* [PutObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutObject.html)
* [CreateBucket](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateBucket.html)

#### WARNING
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` .

See also: [AWS API Documentation](https://docs.aws.amazon.com/goto/WebAPI/s3-2006-03-01/ListObjectsV2)

`list-objects-v2` is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the `--no-paginate` argument.
When using `--output text` and the `--query` argument on a paginated response, the `--query` argument must extract data from the results of the following query expressions: `Contents`, `CommonPrefixes`

## Options

`--bucket` (string) [required]

> > **Directory buckets** - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format \`\` *Bucket-name* .s3express-*zone-id* .\*region-code\* .amazonaws.com\`\` . Path-style requests are not supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must follow the format \`\` *bucket-base-name* –*zone-id* –x-s3\`\` (for example, \`\` *amzn-s3-demo-bucket* –*usw2-az1* –x-s3\`\` ). For information about bucket naming restrictions, see [Directory bucket naming rules](https://docs.aws.amazon.com/AmazonS3/latest/userguide/directory-bucket-naming-rules.html) in the *Amazon S3 User Guide* .

> > **Access points** - When you use this action with an access point for general purpose buckets, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When you use this action with an access point for directory buckets, you must provide the access point name in place of the bucket name. When using the access point ARN, 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 action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see [Using access points](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-access-points.html) in the *Amazon S3 User Guide* .

> #### NOTE
> > Object Lambda access points are not supported by directory buckets.

> **S3 on Outposts** - When you use this action with S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form \`\` *AccessPointName* -*AccountId* .\*outpostID\* .s3-outposts.\*Region\* .amazonaws.com\`\` . When you use this action with S3 on Outposts, the destination bucket must be the Outposts access point ARN or the access point alias. For more information about S3 on Outposts, see [What is S3 on Outposts?](https://docs.aws.amazon.com/AmazonS3/latest/userguide/S3onOutposts.html) in the *Amazon S3 User Guide* .

`--delimiter` (string)

> A delimiter is a character that you use to group keys.

> > `CommonPrefixes` is filtered out from results if it is not lexicographically greater than the `StartAfter` value.

> #### NOTE
> * **Directory buckets** - For directory buckets, `/` is the only supported delimiter.
> * **Directory buckets** - When you query `ListObjectsV2` with a delimiter during in-progress multipart uploads, the `CommonPrefixes` response parameter contains the prefixes that are associated with the in-progress multipart uploads. For more information about multipart uploads, see [Multipart Upload Overview](https://docs.aws.amazon.com/AmazonS3/latest/dev/mpuoverview.html) in the *Amazon S3 User Guide* .

`--encoding-type` (string)

> Encoding type used by Amazon S3 to encode the [object keys](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html) in the response. Responses are encoded only in UTF-8. An object key can contain any Unicode character. However, the XML 1.0 parser can’t parse certain characters, such as characters with an ASCII value from 0 to 10. For characters that aren’t supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response. For more information about characters to avoid in object key names, see [Object key naming guidelines](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html#object-key-guidelines) .

> #### NOTE
> When using the URL encoding type, non-ASCII characters that are used in an object’s key name will be percent-encoded according to UTF-8 code values. For example, the object `test_file(3).png` will appear as `test_file%283%29.png` .

> Possible values:

> * `url`

`--prefix` (string)

> Limits the response to keys that begin with the specified prefix.

> #### NOTE
> **Directory buckets** - For directory buckets, only prefixes that end in a delimiter (`/` ) are supported.

`--fetch-owner` | `--no-fetch-owner` (boolean)

> The owner field is not present in `ListObjectsV2` by default. If you want to return the owner field with each key in the result, then set the `FetchOwner` field to `true` .

> #### NOTE
> **Directory buckets** - For directory buckets, the bucket owner is returned as the object owner for all objects.

`--start-after` (string)

> StartAfter is where you want Amazon S3 to start listing from. Amazon S3 starts listing after this specified key. StartAfter can be any key in the bucket.

> #### NOTE
> This functionality is not supported for directory buckets.

`--request-payer` (string)

> Confirms that the requester knows that she or he will be charged for the list objects request in V2 style. Bucket owners need not specify this parameter in their requests.

> #### NOTE
> This functionality is not supported for directory buckets.

> Possible values:

> * `requester`

`--expected-bucket-owner` (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).

`--optional-object-attributes` (list)

> Specifies the optional fields that you want returned in the response. Fields that you do not specify are not returned.

> #### NOTE
> This functionality is not supported for directory buckets.

> (string)

> > Possible values:

> > * `RestoreStatus`

Syntax:

```
"string" "string" ...
```

`--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](https://docs.aws.amazon.com/cli/latest/userguide/pagination.html) 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](https://docs.aws.amazon.com/cli/latest/userguide/pagination.html) 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](https://docs.aws.amazon.com/cli/latest/userguide/pagination.html) in the *AWS Command Line Interface User Guide* .

`--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`.

`--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

## Global Options

`--debug` (boolean)

Turn on debug logging.

`--endpoint-url` (string)

Override command’s default URL with the given URL.

`--no-verify-ssl` (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

`--no-paginate` (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

`--output` (string)

The formatting style for command output.

* json
* text
* table
* yaml
* yaml-stream
* off

`--query` (string)

A JMESPath query to use in filtering the response data.

`--profile` (string)

Use a specific profile from your credential file.

`--region` (string)

The region to use. Overrides config/env settings.

`--version` (string)

Display the version of this tool.

`--color` (string)

Turn on/off color output.

* on
* off
* auto

`--no-sign-request` (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

`--ca-bundle` (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

`--cli-read-timeout` (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

`--cli-connect-timeout` (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

`--cli-binary-format` (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob `fileb://` will always be treated as binary and use the file contents directly regardless of the `cli-binary-format` setting. When using `file://` the file contents will need to properly formatted for the configured `cli-binary-format`.

* base64
* raw-in-base64-out

`--no-cli-pager` (boolean)

Disable cli pager for output.

`--cli-auto-prompt` (boolean)

Automatically prompt for CLI input parameters.

`--no-cli-auto-prompt` (boolean)

Disable automatically prompt for CLI input parameters.

`--cli-error-format` (string)

The formatting style for error output. By default, errors are displayed in enhanced format.

* legacy
* json
* yaml
* text
* table
* enhanced

## Examples

#### NOTE
To use the following examples, you must have the AWS CLI installed and configured. See the [Getting started guide](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html) in the *AWS CLI User Guide* for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See [Using quotation marks with strings](https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-parameters-quoting-strings.html) in the *AWS CLI User Guide* .

Name -> (string)

> The bucket name.

Prefix -> (string)

> Keys that begin with the indicated prefix.

> #### NOTE
> **Directory buckets** - For directory buckets, only prefixes that end in a delimiter (`/` ) are supported.

Delimiter -> (string)

> Causes keys that contain the same string between the `prefix` and the first occurrence of the delimiter to be rolled up into a single result element in the `CommonPrefixes` collection. These rolled-up keys are not returned elsewhere in the response. Each rolled-up result counts as only one return against the `MaxKeys` value.

> #### NOTE
> **Directory buckets** - For directory buckets, `/` is the only supported delimiter.

MaxKeys -> (integer)

> Sets the maximum number of keys returned in the response. By default, the action returns up to 1,000 key names. The response might contain fewer keys but will never contain more.

CommonPrefixes -> (list)

> All of the keys (up to 1,000) that share the same prefix are grouped together. When counting the total numbers of returns by this API operation, this group of keys is considered as one item.

> A response can contain `CommonPrefixes` only if you specify a delimiter.

> > `CommonPrefixes` contains 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/` . All of the keys that roll up into a common prefix count as a single return when calculating the number of returns.

> #### NOTE
> * **Directory buckets** - For directory buckets, only prefixes that end in a delimiter (`/` ) are supported.
> * **Directory buckets** - When you query `ListObjectsV2` with a delimiter during in-progress multipart uploads, the `CommonPrefixes` response parameter contains the prefixes that are associated with the in-progress multipart uploads. For more information about multipart uploads, see [Multipart Upload Overview](https://docs.aws.amazon.com/AmazonS3/latest/dev/mpuoverview.html) in the *Amazon S3 User Guide* .

> (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 the `encoding-type` request parameter, Amazon S3 includes this element in the response, and returns encoded key name values in the following response elements:

> > `Delimiter, Prefix, Key,` and `StartAfter` .

> Possible values:

> * `url`

KeyCount -> (integer)

> `KeyCount` is the number of keys returned with this request. `KeyCount` will always be less than or equal to the `MaxKeys` field. For example, if you ask for 50 keys, your result will include 50 keys or fewer.

ContinuationToken -> (string)
