Help with script that reads and writes java console Minecraft


I am looking for an easy way to lock game mode (0) for everyone included op on a Minecraft server. It can be a script that every time a player changes game to 1 the script changes back to 0. What the player writes is visible in the java console. I am not good at script programming and my guess is that this is easy for someone who is good script programming. The OS is OSX. I appreciate all help on this.

gamemode <playername> <0|1> Changes the game mode for playername to Survival (0) mode or Creative (1) mode.

Example player player1 writes to set gamemode 1:
gamemode player1 1
Example player player1 writes to set gamemode 0:
gamemode player1 0

I want gamemode to be set to 0 always so I am looking for something like:

Example player player1 writes to set gamemode 1:
gamemode player1 1
2012-02-20 19:59:26 [INFO] player1 issued server command: gamemode player1 1
The script writes:
gamemode player1 0

The script code for the test is something like this
if echo $line | grep -q 'gamemode'
if echo $line | grep -q ' 1'; then
echo $line | sed s/' 0'/' 1'/ >> stdin.commandlist

AIRPORT2-CONFIG(1)					      General Commands Manual						AIRPORT2-CONFIG(1)

airport2-config - Configurator for the Apple AirPort Extreme Base Station ("Snow") SYNOPSIS
airport2-config DESCRIPTION
airport2-config allows you to manage your AirPort base station, just like the AirPort software on Mac OS X. OPTIONS
airport2-config accepts no command-line options. airport2-config is a wrapper script around the Airport2BaseStationConfigurator.jar jar file located in /usr/share/java/airport-utils. You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ- ment variable to 1 to get the debug output from the wrapper script. ENVIRONMENT VARIABLES
DEBUG Set this variable to 1 to get the debug output from the wrapper script. JAVACMD The full path to the Java Virtual Machine to use. By default, the wrapper uses JAVACMD; if it is not set, it looks for JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can be configured using the Debian alternatives system (see update-alternatives(8)). JAVA_HOME The full path where your JDK/JRE is installed. JAVA_BINDIR The full path to the directory where the java executable is located. JAVA_ARGS Extra command-line arguments to be passed to the Java Virtual Machine. AUTHOR
airport2-config was written by Jon Sevy <>. This manual page was written by Julien BLACHE <>, for the Debian project (but may be used by others). May 20, 2006 AIRPORT2-CONFIG(1)
