javascript - How to delete lots of mongodb collections at once?

Question

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.

Is there a way to select a bunch of collections at once to delete them?

Answer 1

For regex you can use string.match

db.getCollectionNames().forEach(function(c) {
    if(!c.match("^system.indexes")) { 
        db.getCollection(c).drop();
    }
  });
