MongoDB从控制台运行javaScript文件并输出

Question

I am trying to create some mongoDB script (files upload to collections, find, create new collections etc). Though get confused. When I run in console:

> use importCSV    
> db.people.find().pretty()

I get documents from collection on my screen, though when I run load command

> load('e:/work/parse/script.js')

i get output

true

Here javaScript file list

db = db.getSiblingDB('importCSV');
db.people.find().pretty();

I do it for debug purpose, so I create javaScript line by line to get what I want, and I need to see step by step some commands output. If I put to javaScript file command like this

print('Print from javaScript file');

it prints to console without any problems.

Why I get "true" when run from file instead of console output, and how to get list of documents printed when run from javaScript file?

Thanks

This is an expected behaviour. You need to iterate through the cursor and print each document explicitly using a .forEach loop because you are not using the interactive shell.

db = db.getSiblingDB('importCSV');
db.people.find().forEach(function(doc) {
    printjson(doc);
}
