Startup script for a Red Hat SCL based node.js application which should run on startup - Hubot. http://github.com/github/hubot (Note, this isn't a _good_ example, simply _an_ example).

hubot

#!/bin/bash
# hubot
# chkconfig: 345 20 80
# description: hubot
# processname: hubot

# This script assumes you have a user called "hubot" on your system and that hubot is installed in /opt/hubot
#

# Save Environement Variables in /opt/hubot/hubot/bin/hubot.env

#   export HUBOT_GTALK_USERNAME='[email protected]'
#   export HUBOT_GTALK_PASSWORD='abc123''
