如何一次删除大量的mongodb集合？ [英] How to delete lots of mongodb collections at once?

问题描述

在我的数据库中有很多mongodb集合，我需要删除。它们都有类似的名称，如果只能使用通配符，那么很容易删除它们。但它看起来不像他们可以。

There are a lot of mongodb collections in my database that I need to delete. They all have similar names, and it would be easy to delete them if only wildcard characters could be used. But it doesn't look like they can.
