I'm pretty sure that there isn't a command for that, but it says what everyone does in the server hosting thing. (Only the host can see it)
There is no command block in minecraft. If you go to the Minecraft WiKi it will have all the information you need for anything in the game.
First, you must turn cheats on in your world. Then, you do the command /gamerule keepinventory true.
You need to be in creative mode in order to input commands into the command block.
The only way to get a command block in Minecraft is to have cheats on in your world.Once you generated a world like that, type in the following command:/give [your Minecraft character's name] 137 [amount up to 64]That will give you a command block.
/toggledownfall
the command block doesn't have an ip.
/toggledownfall to stop or make rain in minecraft
/summon primedTnt
Its when you are in command to do something the gov. Tells you to.
If you're using WorldEdit. The command is, /tree redwood
You can't have commands on minecraft classic but you can in multiplayer classic
not that is made yet
