.mongorc.js

The .mongorc.js file is used if you want to have some JavaScript loaded every time you start the mongo shell:

On Linux, Unix, and OS X mongo looks for this file in $HOME/.mongorc.js.
On Windows, mongo.exe looks for this file in %HOME%.mongorc.js or %HOMEDRIVE%%HOMEPATH%.mongorc.js.

Typically you only want to store re-usable functions in your .mongorc.js.

Other ways to load JavaScript into a `mongo` shell session include:

using the load() command in a mongo shell: load("/path/to/something.js").
passing a JavaScript filename as a command line parameter when starting the mongo shell: mongo /path/to/something.js
pasting JavaScript directly into the mongo shell (e.g. copy & paste from a tutorial)
