Linux Starmade Startup Script

[WASasquatch]

I needed a way to start my server without human interaction when the server restarts (or w/e happens) and a easier way to restart and issue commands (since the console goes nuts with notifications and you can't even execute commands via the console) This script is based on my modified version of the MineCraft startup script I had released some years ago. Feel free to use it!

Installation

Firstly, you will need screen installed. If you do not have it, run apt-get install screen

CD into /etc/init.d/ and create a new file called "starmade" with nano or your favorite editor. Paste in the script above and make the changes to the paths as needed. Save the script.

Next give the script proper permissions with chmod a+x /etc/init.d/starmade

Next update your serice with update-rc.d /etc/init.d/starmade defaults


Usage

You server should start with your linux machine upon it's next reboot. To start the server manually run service starmade start

Additionally run service starmade help for a list of commands.

If anyone is interested I will upload a systemd compatible version soon, once I\'m implemented a config file for it.
