+- Start a Minecraft server and generate a world if it doesn't exist:
+
+`java -jar {{path/to/server.jar}} --nogui`
+
+- Set the minimum and maximum amount of memory a server is allowed to have (Note: Setting them the same prevents lag caused by heap scaling):
+
+`java -Xms{{1024M}} -Xmx{{2048M}} -jar {{path/to/server.jar}} --nogui`
+
+- Start a server with a GUI:
+
+`java -jar {{path/to/server.jar}}`

+
+`stop`
