--transfer_config

--update_credentials

When specified, updates the transfer configuration credentials. The default value is false.

--use_legacy_sql

bq wait

The wait command waits some number of seconds for a job to finish.

The wait command uses the --job_id global flag and the following command-specific flags.

[INTEGER]

An integer value >= 0 that specifies the wait time (this value is not a flag — you specify the integer on the command line). If you enter 0, the command polls for job completion and returns immediately. If you do not specify an integer value, the command waits forever.

--fail_on_error

When specified, after the wait time elapses, exit with an error if the job is still running, or ended in failure. The default value is true.

--wait_for_status

When specified, wait for a particular job status before exiting. Possible values include:

• PENDING
• RUNNING
• DONE

The default value is DONE.
