Iterate through all collections of all the dbs in MongoDB

I need to Iterate through all the collections of each db. For each collection i need to do a collectionName.find() and print the json

Below is what i have tried:

#db_get_all_collections.js

db.adminCommand("listDatabases").databases.forEach(function(d) {
mdb = db.getSiblingDB(d.name);
mdb.getCollectionNames().forEach(function(c) {
s = mdb[c].find();
prinjson(s)
}
});


I am dumping the output to a file as below

mongo admin -u <<user_name>> -p <<password>> < db_get_all_collections.js > output.json


However in output.json i see

MongoDB shell version: 3.0.3
connecting to: admin

bye
