db.cloneDatabase(fromhost)
db.copyDatabase(fromdb, todb, fromhost)
db.createCollection(name, { size : ..., capped : ..., max : ... } )
db.getName()
db.dropDatabase()
// runs the collstats] command on each collection in the database
db.printCollectionStats()
db.currentOp() displays the current operation in the db

db.repairDatabase()
db.version() current version of the server

db.foo.drop() drop the collection db.foo.dropIndex(name) db.foo.dropIndexes() db.foo.getIndexes() db.foo.ensureIndex(keypattern,options) - options object has these possible fields: name, unique, dropDups db.foo.find( [query] , [fields]) - first parameter is an optional query filter. second parameter is optional set of fields to return. e.g. db.foo.find( { x : 77 } , { name : 1 , x : 1 } ) db.foo.find(...).count() db.foo.find(...).limit(n) db.foo.find(...).skip(n) db.foo.find(...).sort(...) db.foo.findOne([query]) db.foo.getDB() get DB object associated with collection db.foo.count() db.foo.group( { key : ..., initial: ..., reduce : ...[, cond: ...] } ) db.foo.renameCollection( newName ) renames the collection db.foo.stats() db.foo.dataSize() db.foo.storageSize() - includes free space allocated to this collection db.foo.totalIndexSize() - size in bytes of all the indexes db.foo.totalSize() - storage allocated for all data and indexes db.foo.validate() (slow) db.foo.insert(obj) db.foo.update(query, object[, upsert_bool]) db.foo.save(obj) db.foo.remove(query) - remove objects matching query remove({}) will remove all
