Hello this is a question pertaining to my Raspberry Pi but since it is a general Linux question, I posted here instead.

I'm running a Nukkit Minecraft server on my Raspberry Pi (I know it doesn't have good hardware but I'm experimenting) and googling different ways to make a bash file for Linux. I have made the file startNukkit.whateverextension. I have come to this:

!#/bin/bash/

gnome-terminal -e "java -jar home/pi/Desktop/Nukkit/nukkit.jar; exec bash""

But there are multiple things I want to solve. First, when I double click the bash file it will prompt me to: "Execute", "Execute in Terminal", "Open", and "Cancel". Instead, I would like to run it right away without this prompt.

And because this is a Minecraft server, I can only see the results of the server in the terminal, such as who connects to my server. But if I click on "Execute in Terminal", the terminal will show and then close. I thought this could be solved by "exec bash"" as explained here. To keep the terminal window open.

And finally, I would like to make this execute in startup similar to how in Windows has a startup folder where any file you place in this folder will execute in startup.

If you found that this is a duplicate question of a similar post. Please notify me before downvoting or deleting this post. I have made this post only because I want all these questions answered as one to help those who are googling the same thing. Thank you! And sorry for the disclaimer!

As a systemd service

(You didn't mention a specific GNU/Linux distribution, I think most common ones have systemd available though)

If you move your .jar file to some accessible place like /opt then you could have systemd run your server after startup as nobody or some other low-privilege user.

In addition to potentially running without access to home directories, etc. you can also configure systemd to restart a service after failure and many other things.

See man systemd.service, man systemd.exec, man systemd.unit, etc.

nukkit.service

[Unit]
Description=Nukkit Server
After=syslog.target
After=network.target

[Service]
Type=simple
User=nobody
Group=nobody
ExecStart=java -jar /opt/Nukkit/nukkit.jar

[Install]
WantedBy=multi-user.target

Watching output

Where you have /etc/systemd/system/nukkit.service and have:

• systemctl enable nukkit


• systemctl start nukkit

then journalctl -f -u nukkit should follow the most recent log messages from systemd unit nukkit. Your system may be using syslog or some other facility though; in that case you could configure logging to a specific file, etc.
