list-things

Description

Lists your things. Use the attributeName and attributeValue parameters to filter your things. For example, calling ListThings with attributeName=Color and attributeValue=Red retrieves all things in the registry that contain an attribute Color with the value Red .

Requires permission to access the ListThings action.

Note

You will not be charged for calling this API if an Access denied error is returned. You will also not be charged if no attributes or pagination token was provided in request and no pagination token and no results were returned.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-things 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: things

Synopsis

  list-things
[--attribute-name <value>]
[--attribute-value <value>]
[--thing-type-name <value>]
[--use-prefix-attribute-value | --no-use-prefix-attribute-value]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--attribute-name (string)

The attribute name used to search for things.

--attribute-value (string)

The attribute value used to search for things.

--thing-type-name (string)

The name of the thing type used to search for things.

--use-prefix-attribute-value | --no-use-prefix-attribute-value (boolean)

When true , the action returns the thing resources with attribute values that start with the attributeValue provided.

When false , or not present, the action returns only the thing resources with attribute values that match the entire attributeValue provided.

--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

Example 1: To list all things in the registry

The following list-things example lists the things (devices) that are defined in the AWS IoT registry for your AWS account.

aws iot list-things

Output:

{
    "things": [
        {
            "thingName": "ThirdBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/ThirdBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 2
        },
        {
            "thingName": "MyOtherLightBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyOtherLightBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 3
        },
        {
            "thingName": "MyLightBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyLightBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 1
        },
        {
        "thingName": "SampleIoTThing",
        "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/SampleIoTThing",
        "attributes": {},
        "version": 1
        }
    ]
}

Example 2: To list the defined things that have a specific attribute

The following list-things example displays a list of things that have an attribute named wattage.

aws iot list-things \
    --attribute-name wattage

Output:

{
    "things": [
        {
            "thingName": "MyLightBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyLightBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 1
        },
        {
            "thingName": "MyOtherLightBulb",
            "thingTypeName": "LightBulb",
            "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyOtherLightBulb",
            "attributes": {
                "model": "123",
                "wattage": "75"
            },
            "version": 3

    ]
}
