You can also enable a batch-like mode directly from dbx by setting the dbx environment variables rtc_auto_continue and rtc_error_log_file_name (see Setting dbx Environment Variables).
If rtc_auto_continue is set to on, runtime checking continues to find errors and keeps running automatically. It redirects errors to the file named by the dbx environment variable rtc_error_log_file_name. (See Setting dbx Environment Variables.) The default log file name is /tmp/dbx.errlog.uniqueid. To redirect all errors to the terminal, set the rtc_error_log_file_name environment variable to /dev/tty.
By default, rtc_auto_continue is set to off.
