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.
