list-ledgers

Description

Returns an array of ledger summaries that are associated with the current Amazon Web Services account and Region.

This action returns a maximum of 100 items and is paginated so that you can retrieve all the items by calling ListLedgers multiple times.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  list-ledgers
[--max-results <value>]
[--next-token <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <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 | --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.

See ‘aws help’ for descriptions of global parameters.

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:

Output

Ledgers -> (list)

The array of ledger summaries 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.
