I just want to run a .js script against a particular mongodb database, but can't seem to get the correct syntax.

echo "print(db.address.find().limit(1));" > test.js
mongo test.js

How do I select the database that this will be executed on, I've tried various combinations of use foo with no success.

> show dbs                      
admin   (empty)
local   (empty)
foo 0.203125GB
bar 0.203125GB

I would like to use foo in this case.

You can use the db.getSiblingDB() method, as mentioned here and in the MongoDB documentation.

// Equivalent for "use <db>" command in mongo shell
db = db.getSiblingDB('foo')

This is particularly useful when writing scripts using the mongo shell where the use helper is not available. Or when you cannot refer to the DB on the connection string.
