Clone and run this on a new EC2 instance running Ubuntu 12.04.2 LTS to configure your bash and emacs development environment as follows:

cd $HOME
git clone https://github.com/startup-class/dotfiles.git
ln -sb dotfiles/.screenrc .
ln -sb dotfiles/.bash_profile .
ln -sb dotfiles/.bashrc .
ln -sb dotfiles/.bashrc_custom .
mv .emacs.d .emacs.d~
ln -s dotfiles/.emacs.d .

See also http://github.com/startup-class/setup to install prerequisite programs. If all goes well, in addition to a more useful prompt, now you can do emacs -nw hello.js and hitting C-c! to launch an interactive SSJS Original Concept from (https://class.coursera.org/startup-001/lecture/index)

I've since made it my own, with a lot of help / inspiration from others
