Copy Files To Dev Null Minecraft
Build a Minecraft Server on Linux Build a Vanilla Minecraft Server on Linux The Aquatic Update 1.13.2 Building 1.13.x Spigot.jar works. It is recommended to build a new world but upgrading existing 1.12 worlds should be done with caution. If you decide to upgrade an existing world then build the latest spigot jar file as new builds are released daily. I have not had any problems upgrading to 1.13.2, but make sure you backup your world just in case.

Copy to something like a NULL device etc? This is the only way I can think of that will actually attempt to open files for at least read access to perform a copy on the file but send it off to a bit bucket. 3/8 inch to mm.

Spigot 1.13.2 is still considered developmental but it has been solid, especially the latest builds. Minecraft Server Version: 1.13.2 Oracle Java Version: 8u201 Approximate time to complete: 15 to 30 minutes depending on your server. This also depends on your comfort level working from the Linux command line.
