Startscript für OpenSim etc

[Bogus Curry]

Hallo zusammen ;D

Ich hab ein schönes Startscript gefunden das eigentlich für einen Minecraft Server gedacht war. Das ganze wurde dann von einen lieben User umgeschrieben, so das dieses auch für OpenSim/Arriba oder halt WhiteCore Sim brauchbar ist.

Hier der Code

Code:

#!/bin/bash
