Mongo shell commands can be executed in console mode. The inputs are directly forwarded to the native mongo shell and are not formatted or modified by the application.
This is a new feature since version 1.2.0! The former console mode (C) is now moved to server side script mode (S).
Here you will find the documentation of the Mongo shell commands: http://docs.mongodb.org/manual/core/crud-introduction/
There is no pager in server side script mode. Just as in the mongo shell, there are only 10 records returned. When you type "it", the next 10 records are loaded.
If you open a shell for a collection which requires authentication you have to authenticate again in the shell. Use the following commands.
