Values

trueDefault	On
false	Off

Arguments

true|falseOptional: true turns the rule on, false turns it off. Leave it out to show the current value.

What it does

With true, every command block that runs a command posts a gray message to ops in chat and logs it, which can flood chat on maps with clock circuits. Turn it off on servers with many repeating command blocks.

Run it on your server

On a SLASHPLAY server, type it in the Console tab without the leading slash; in game, operators type it in chat with the slash. New to this? Start a Minecraft server first.
