I dont think so - the docs suggest you get a full Linux that your code runs on, not just a limited sandbox, one of the blogs mentioned running binary code. So I don't think it is being sandboxed at the language level. Especially as they talked about adding more languages soon.

Yes, the Lambda function is run in an Amazon Linux environment.

I published some explorations of that environment here: http://alestic.com/2014/11/aws-lambda-environment

Let me know in the comments on that article what other commands you'd like to see output for.
