| − | The following is an init script that I wrote for starting, stopping, and monitoring OpenSim on Linux systems. It makes an assumption that the opensim working instance is in OpenSimPath (seen in the script). It also makes some other assumptions on environment, including that you are running mysql, so while it may not be suitable for all environments, it has been very useful for the environments that I run.
