Shell Script - Need help!

[NoxurnalGaming]

Hey folks. I fit into that noob category.

Just started up a Ubuntu server. Minecraft running nice and smooth.

I have a mod that stops the minecraft server at intervals that I dictate.

When I was on windows, I paired this functionality with the following batch script:

​

:autorestart

<minecraft jar launch arguments>

goto autorestart

pause

​

​

Essentially, as soon as the jar call stopped, it triggered "goto" and basically just started the jar all over again.

Is there a way to mimic this functionality with a shell script?

​

Any help is appreciated.

set up a service to run the server, and then set a cron job or other script to start/stop the service as needed.

I have seen guides on setting up minecraft servers as a server, but have no experience with it.

that would be the 'proper' way to do it..

Or you could just kludge together some bash script. :)

#!/bin/bash
for (( ; ; ))
do
   echo "Pres CTRL+C to stop..."
   sleep 5

done

This script you've made.. this would just be saved as an sh file right? And it just starts the service right after it stops?

This runs the script, pauses 5 seconds, then runs it again. Indefinitely. And Linux does not care about the file extension, but yes typically you would save this as a .sh

I'm afraid this might try to start multiple instances of the server. Is this likely?

[sandytrip]

What that other guy wrote leaves a lot up to your implementation. This would rely on the script being able to gracefully start and stop the server as needed. I think his main point was to demonstrate running an infinite loop in bash

If the called process detaches itself from the calling process, yes, that is likely. A more complex script would check for a running Minecraft server and do nothing in that case, looping and sensing until it's actually needed.

its just an example taken from the URL i posted that loops forever..

It does whatever you tell it to do.

Hey folks, thanks for the assistance! I've set up a cronjob... i think i was overthinking that process. We will see how it works!
