I'm working in room 5025 if you want to come chat.

Context: Previously, in version 2.4, our javascript parser would allow me to pass javascript files with shell commands such as "use agg" to switch context to the agg database.

Problem: In the 2.6.0 shell, I can't pass the shell .js files with "use agg" because it isn't valid javascript.

Instead, I'm reassigning db with something like

db = new Mongo().getDB("agg")

but this causes its own problems. For instance, if I have test.js:

db = new Mongo().getDB("agg")
db.foo.insert( { a : 1 } )

then if I type mongo test.js, I get:

$ mongo test.js
MongoDB shell version: 2.6.0
connecting to: test

This is confusing for students taking the class.

I can type

 
mongo agg test.js
MongoDB shell version: 2.6.0
connecting to: agg

but the agg is doing nothing.

Is there any elegant way to specify, in a .js file, which database we're dealing with in a way that's consistent with the behavior of the script?
