Indeed, it is possible to use a wildcard in the path to bq mkdef (and bq load) so that you can match multiple files: ... Because the source and destination datasets are both BigQuery datasets, the initiator needs to have permission to initiate data transfers, list tables in the source dataset, view the source dataset, and edit the destination dataset.
