Editing Tutorials/Setting up a server (section)

=== Writing a script to launch the server ===
It's definitely boring to have to remember the command-line options for your server every time you launch it. Luckily, we can write it down in a file and just run that instead.

==== On Windows ====
The windows version of a script is called a batch file. Create a text file in the folder where you put the jar as "start.bat", and then right click it to edit using notepad. Paste the following in:

<syntaxhighlight lang="bat">
@ECHO OFF
java -Xms1024M -Xmx2048M -jar minecraft_server.jar --nogui
pause
</syntaxhighlight>

Double click the file to start your server. You may get a "Class_Not_Found" and ServerGuiConcole error, just ignore these errors
and you should see your "Server Thread/INFO" dialog start the server.

The "pause" command is there to keep the window open so you can read what happened after the server stops.

==== On macOS, Linux, and FreeBSD ====
All these systems use a common scripting language called the "POSIX shell script" on the command line. Create a text file in the folder where you put the jar as "start.sh" and write the following in:

<syntaxhighlight lang="sh">
#!/bin/sh
cd "$(dirname "$0")"
exec java -Xms1G -Xmx1G -jar server.jar --nogui
</syntaxhighlight>

Now save the file. Run {{code|chmod a+x start.sh}} (or path to wherever you put the script) to make it executable. You can now run the file by double-clicking or by running {{code|./start.sh}} in the folder (or using a whole path from outside there).

If you want to add a pausing part like the Windows example, remove the {{code|exec}} word, and add a line of {{code|read -n 1 -p "Waiting..."}} to the end. This is useful if you are running the script by double-clicking on the GUI.

==== On Plan 9 ====
(I don't use Plan 9, so I have absolutely no idea how to use the rc, psh, acme, snarf magic. Someone please add it.)
