   Answering your question: params in not templated by default, nor by the BashOperator. You can check in any operator which attributes are templated by looking for the `template_fields` attribute. In the BashOperator, you'll see the `bash_command` in there and thus you could run your operator as such:
   
   ```python
   upload_file_ftp_op = BashOperator(
      task_id='upload_file_ftp_task',
      bash_command="python3.6 /home/ubuntu/airflow/scripts/ranker.py  product_dwh-{{ execution_date.strftime('%s') }}.csv" ,
      dag=dag,
   )
   ```
