mongodb - File write operations in mongo script?

Is this possible to write the query result to the file from mongo js script. I have searched a lot, but I didn't find any solution.

ex:-

cursor = db.users.find();

while(cursor.hasNext()) {
  cursor.next();
  // writing the cursor output to file ????<br/>
}

You could use print and then redirect output:

script.js:

cursor = db.users.find();
while(cursor.hasNext()){
    printjson(cursor.next());
}

then run the script and redirect output to a file:

mongo --quiet script.js > result.txt
