Node JS app and a shell script communicating

A Node JS app and a shell script are communicating with each other via a Redis server. This way it is possible to influence the behavior of that shell script and to issue commands via a browser.

Operating System is Xubuntu 12.04 x86. Browser is Chromium 24.0.1312.56. Redis Server 2.2.12 and NodeJS 0.6.12 were used for that experiment.
