title: How to delete multiple bigquery datasets of a project in single bq command
body: <p>I have around 200 <code>BigQuery</code> datasets in my project. I want to delete them as I am doing some cleanup activities. I see the command <code>bq rm -r -f -d &lt;var&gt;project_id:dataset&lt;/var&gt;</code> which is for single dataset and i need to run each time. Is there anyway to delete bulk datasets in a project ?</p>
