I’m working with a collection that someone else created, and I need to find out whether an index is unique. Is there anyway to do this from the mongo shell?

You can search for indexes with:
db.system.indexes.find();To search for a unique index:
db.system.indexes.find({"unique": true});With that, you can also add more search parameters to find specific indexes by namespace, key, etc.
