To get an overview of the available options provided by the management script, be sure to have a look at the help page or read the according section on the ArchWiki article [1].

You can quit the console without shutting down the server by press ctrl+a d (first ctrl+a and after releasing the buttons press d). This will detach your input from the server console. The attaching and detaching is done with GNU screen since it lets you view and type into the console, send single commands to it and keep it alive without a connected user. Take a look at the the command overview at the ArchWiki [2] to get a feel for its power. (@carmelo12341)

@Synthead
Though I agree that it probably is not the way most Arch developers do it, I still think it makes sense. Not disabling a service might leave broken symlinks on the filesystem and IMHO it is the job of a packager manager to cleanly remove a package when asked to.
Nevertheless I will do whatever the majority wants to. If people start wandering what is going on, I will remove the according lines.

P.S. the package is "nonstandard" in several ways:
* I remove the minecraft user on un-installation. However you must consider that the ownership of the server root is changed and the user is exclusively used by this package.
* The server root is on /srv which is also unusual. IMHO this is simply where it belongs [1].
No general rule can fit every package and like above I am willing to debate.

It's a really bad idea to disable and stop the minecraft-server service in the .install script. The user probably wants this, but it's not the Arch Way (tm) to do it this way.

@bronze
You (your user) cannot view a process which is owned by a different user however root can see everything. If you have the according sudo capabilities you can execute a single command as a different user by using `sudo -u minecraft <command>`. I assume you can construct the necessary command from there.
Either way all of the above would have been unnecessary if you would have continued reading the Wiki [1] or if you would have taken a look at the help page ;D The simplest solution to your problem is using the management script: Type `minecraft --help` for a list of available option, spoiler use `minecraftd console` to connect to the console. In order to disconnect, see the pinned comment.

The minecraft arch wiki mentions "Either way the server is encapsulated in a screen session which is owned by the minecraft user." However, screen -ls didn't return any screens.
I checked if screen was running. I did find SCREEN running ps -aux:

root 5302 0.0 0.0 23932 2656 ? Ss 07:53 0:11 SCREEN -dmS minecraft /bin/bash -c cd '/srv/minecraft'; java -server .....

How do I "connect" to the screen named "minecraft"? Why is screen written in all caps?

[EDIT] I managed to connect to the screen via "su root" and "su minecraft" (user minecraft doesn't have a password). Is that the only way to connect to the screen?

@Tmk
I am thrilled to hear that you intend to use it in an production environment. Should you encounter any setbacks be sure to let me know how I may help. My mail address is contained within the PKGBUILD and the code is hosted at github [1]. Keep in mind that the idle server is a somewhat hacked solution since netcat occupies that port as long as the server is down and it takes some time (depending on your setup) to get it back up.
Btw. the script should also work with multiple parallel servers (e.g. on different ports) simply by setting unique environment variables (especially SESSION_NAME). However I have not tested this setup yet.

EDIT: Concerning your question about the graceful shutdown depends on your setup. If you start the server by hand (using `minecraftd start`) you must also shut it down by hand (using `minecraftd stop`). If there is no player online the server will shutdown immediately, otherwise it will grant players a few seconds to clean up leftover work. However if you use the provided systemd service file, a graceful shutdown (`minecraftd stop` with the same effect as stated above) should be automatically trigger on a system reboot.

Ah I see, thank you for the change! It work's. Don't worry being "late", you were not. I will switch to production with your script, the idle_server saves me headaches with stuff running in the always-loaded-chunks. I have one more question, will the running Minecraft server be gracefully stopped if I reboot the system or would that be a crash? Thanks again!

@Tmk
Thanks a lot for the bug report and sorry for the late response!
Previously screen was used to select a session with a specific well defined name however apparently screen selects anything starting with the specified pattern. This let to some confusion between the server and the idle_server. To circumvent this behaviour I simply changed the naming schema for the idle_server.

Hello, thanks for the nice package!

The idle server is not working for me, "An error occured while trying to reset the idle server!". Once the minecraft server sleeps I cannot reconnect from the game client. I don't understand the script enough, unfortunately. I made a screenshot [1], maybe somebody has an idea?

@leifurhauks
Strange, it is working well for me on two different machines and on a clean installation. The game_command function in the script [1] apparently is not working as expected for you. The logic of this function is like this: enable logging for the screen session to file /tmp/minecraftd_screen_command_dump.txt, trigger the command, wait, disable logging for the screen session, cat file, rm file. I assume you installed screen properly, performed no partial upgrade, your /tmp folder is configured and you have shut down your server at least once since you updated to screen version 4.4.0, then I would guess the logfile is not set correctly. Try issuing the following command:
sudo -u minecraft screen -S minecraft -X logfile "/tmp/minecraftd_screen_command_dump.txt"
and see if that fixes the issue for the currently running server. Be sure to check every of the above mentioned pitfalls before!

Thank you for this great package!

When I run minecraftd command <command>, I always get the following:

cat: /tmp/minecraftd_screen_command_dump.txt: No such file or directory
rm: cannot remove '/tmp/minecraftd_screen_command_dump.txt': No such file or directory
