Mongorc.js file

When booting, MONGO checks a JavaScript file in the user's home directory. Mongorc.js. If found, MONGO resolves the. Mongorc.js content before displaying the message for the first time.
If you use the shell to execute a JavaScript file or evaluate an expression, either by using the--eval option at the command line or by specifying a. js file to Mongo,mongo will read the. mongorc.js file after completing the processing of the JavaScript.
You can use the--NORC option to prevent loading. Mongorc.js.
