To place a command block and change the commands, you need to be in Creative Mode and must have the “maphack” privilege. A new command block does not have any commands and does nothing. Rightclick the command block (in Creative Mode!) to edit its commands. Read the help entry “Advanced topics > Server Commands” to understand how they work. Each line contains a single command. You enter them like you would in the console, but without the leading slash. The commands will be executed from top to bottom.
All commands will be executed on behalf of the player who placed the command block, as if the player typed in the commands. This player is said to be the “commander” of the block.
You can optionally use the following placeholders in your commands:
• “@nearest” is replaced by the name of the player nearest to the command block
• “@farthest” is replaced by the name of the player farthest away from the command block
