list-collections

Description

Returns list of collection IDs in your account. If the result is truncated, the response also provides a NextToken that you can use in the subsequent request to fetch the next set of collection IDs.

For an example, see Listing collections in the Amazon Rekognition Developer Guide.

This operation requires permissions to perform the rekognition:ListCollections action.

See ‘aws help’ for descriptions of global parameters.

list-collections 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: CollectionIds, FaceModelVersions

Synopsis

  list-collections
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

To list the available collections

The following list-collections command lists the available collections in the AWS account.

aws rekognition list-collections

Output:

{
    "FaceModelVersions": [
        "2.0",
        "3.0",
        "3.0",
        "3.0",
        "4.0",
        "1.0",
        "3.0",
        "4.0",
        "4.0",
        "4.0"
    ],
    "CollectionIds": [
        "MyCollection1",
        "MyCollection2",
        "MyCollection3",
        "MyCollection4",
        "MyCollection5",
        "MyCollection6",
        "MyCollection7",
        "MyCollection8",
        "MyCollection9",
        "MyCollection10"
    ]
}

Output

CollectionIds -> (list)

An array of collection IDs.

(string)

NextToken -> (string)

If the result is truncated, the response provides a NextToken that you can use in the subsequent request to fetch the next set of collection IDs.

FaceModelVersions -> (list)

Version numbers of the face detection models associated with the collections in the array CollectionIds . For example, the value of FaceModelVersions[2] is the version number for the face detection model used by the collection in CollectionId[2] .

(string)
