list-ledgers¶

Description¶

Returns all ledgers that are associated with the current Amazon Web Services account and Region.

This action returns a maximum of MaxResults items and is paginated so that you can retrieve all the items by calling ListLedgers multiple times.

Synopsis¶

  list-ledgers
[--max-results <value>]
[--next-token <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]
[--debug]
[--endpoint-url <value>]
[--no-verify-ssl]
[--no-paginate]
[--output <value>]
[--query <value>]
[--profile <value>]
[--region <value>]
[--version <value>]
[--color <value>]
[--no-sign-request]
[--ca-bundle <value>]
[--cli-read-timeout <value>]
[--cli-connect-timeout <value>]

Options¶

--max-results (integer)

The maximum number of results to return in a single ListLedgers request. (The actual number of results returned might be fewer.)

--next-token (string)

A pagination token, indicating that you want to retrieve the next page of results. If you received a value for NextToken in the response from a previous ListLedgers call, then you should use that value as input here.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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.

--output (string)

The formatting style for command output.

json
text
table

--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.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide 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 in the AWS CLI User Guide .

To list your available ledgers

The following list-ledgers example lists all ledgers that are associated with the current AWS account and Region.

aws qldb list-ledgers

Output:

{
    "Ledgers": [
        {
            "State": "ACTIVE",
            "CreationDateTime": 1568839243.951,
            "Name": "myExampleLedger"
        },
        {
            "State": "ACTIVE",
            "CreationDateTime": 1568839543.557,
            "Name": "myExampleLedger2"
        }
    ]
}

Output¶

Ledgers -> (list)

The ledgers that are associated with the current Amazon Web Services account and Region.

(structure)

Information about a ledger, including its name, state, and when it was created.

Name -> (string)

The name of the ledger.

State -> (string)

The current status of the ledger.

CreationDateTime -> (timestamp)

The date and time, in epoch time format, when the ledger was created. (Epoch time format is the number of seconds elapsed since 12:00:00 AM January 1, 1970 UTC.)

NextToken -> (string)

A pagination token, indicating whether there are more results available:

If NextToken is empty, then the last page of results has been processed and there are no more results to be retrieved.

If NextToken is not empty, then there are more results available. To retrieve the next page of results, use the value of NextToken in a subsequent ListLedgers call.
