MongoDB: How To Delete All Records Of A Collection in MongoDB Shell?

Question

I\'ve tried

db.users.remove(*)

Although it returns an error so how do I go about clearing all records?

Answer 1

To remove all the documents in all the collections:

db.getCollectionNames().forEach( function(collection_name) { 
    if (collection_name.indexOf("system.") == -1) {
        print ( ["Removing: ", db[collection_name].count({}), " documents from ", collection_name].join('') );
        db[collection_name].remove({}); 
    }
});
