I am searching for a Linux commandline tool to use the rcon to send Command to the minecraft server.

While I found one in the Minecraft Forum it does not work as expected, most time the Auth Succeeds but the Command does not get executed and the programm quit in reading the results from the Server

Any hints for a working program, or how to fix the mentioned one?

  • You want to send commands from the same machine, or a different one? – Maerlyn Jan 22 '12 at 16:59
  • The same one, I have already used HTTPConsole, but since RCon is build in now, would like to use rcon. – Lairsdragon Jan 22 '12 at 19:14

I'm assuming you're running minecraft in a screen session, since it's the most convenient way to not force you to keep an ssh connection always open.

You can send a command to screen that it forwards to the application running inside it. For example, I am running it in a screen session called minecraft, and every few hours a script runs, forces a save, toggles autosave off, does a backup of my worlds files, then turns autosave back on.

This is how you start a new screen session called minecraft:

screen -S minecraft

then you get a shell, you may also pass the command you want to run automatically instead of getting a shell.

Then you can send commands to that session:

screen -p 0 -S minecraft -X eval "stuff save-all\015"
  • -p 0 sends the message to window 0 in the session
  • -S minecraft is the session name
  • the rest tells to print "save-all" and a newline to the application's stdin

  • Thanks for this suggestion. While this works most of the time, I had problems with this way especially if I am already connected to the screen session. Therefore I would prefer a solution for rcon since there is a second commandchannel which does not rely or interfere with the STDIN.. – Lairsdragon Jan 22 '12 at 20:41

  • Welcome to Gaming. While this program may answer the question, you should explain why you think this program is the one the asker needs, and maybe give a little guide on using it. – Jupotter May 4 '12 at 7:19

Maybe this is an old post, but I recommend these tools (written in Java):

They both work great, recommended
