--follow-next option

--follow-next (-f) option set the output/input field name of the next token. This option is useful for paginated APIs.

For example, s3#ListObjectsV2Output has NextContinuationToken field, and s3#ListObjectsV2Input has ContinuationToken field. You can follow the next token by the following command.

{FieldInOutput}={FieldInInput} format is used for --follow-next option.

$ aws-sdk-client-go s3 list-objects-v2 '{"Bucket": "my-bucket"}' \
  --follow-next NextContinuationToken=ContinuationToken

If the same field name is used in the output and input, you can omit the input field name.

$ aws-sdk-client-go ecs list-tasks '{"Cluster":"default"}' \
  --follow-next NextToken
