The Command Block is a redstone-powered block that was made available in the 1.4 patch for Minecraft. The Command Block will perform server commands when attached to a redstone circuit. This block cannot be crafted, and only server administrators are allowed to place them. Command blocks can only be obtained when cheats are activated, and can still only be used in creative mode, preventing survival players in a server from accessing "staff" abilities. Command blocks are invincible outside of creative mode. With Command blocks, you can perform commands that players can not perform.

To get a command block using cheats, type /give @p minecraft:command_block <amount>.


When attached to a redstone circuit, the Command Block can perform a variety of server commands, such as changing the difficulty or giving players items. There are also gamerules, which are unique commands.

This table shows the list of gamerules:

 Gamerule  What it does
commandBlockOutput Enables/disables text output of command block commands to console


Enables/disables fire spread.
doMobLoot Enables/disables mob drops.
doMobSpawning Enables/disables the spawning of mobs unless you want them to ex: eggs and mob spawners will still spawn mobs.
doTileDrops Enables/disables blocks dropping items when broken (includes TNT destroying blocks).
keepInventory Enables/disables keeping inventory on death.

Enables/disables creepers, ghasts, and Wither blowing up blocks, endermen picking up blocks and zombies breaking doors.

naturalRegeneration Enables/disables regenerating health when hunger is full or close to full.
spectatorsGenerateChunks Whether players in Spectator Mode can generate chunks.
showDeathMessages Whether a message appears in the chat when a player dies
logAdminCommands Whether to log admin commands to server logs
spawnRadius The number of blocks outward from the world spawn coordinates that a player will spawn in when first joining a server or when dying without a spawnpoint
doDaylightCycle Whether the day-night cycle and moon phases should progress
sendCommandFeedback Whether the feedback from commands executed by a player should show up in chat.
reducedDebugInfo Whether the Debug Screen shows all or reduced information
randomTickSpeed How often a random block tick occurs (e.g. plant growth, leaf decay, etc.) per chunk section per game tick.

Gamerules are case sensitive.

You must type in /gamerule before the name of the actual gamerule. True/false tells whether you want to disable the gamerule (false), or enable it (true).

An example of a gamerule command is /gamerule mobGriefing true.

This table shows that commands can be restricted to players on the server.

Shorthand Restriction
@p Nearest player
@r Random player

All players


Furthest Player

An example of a command is:

/give @p minecraft:cobblestone 64

This command will give the nearest player a stack of Cobblestone.

Command Blocks can also be used on other entities as of release 1.8, not 1.7. Watch the snapshot videos. They are the 1.8 ones that talk about the @e selector, using the shorthand @e. This can be used to create custom spawners, and therefore is a very useful tool for mapmakers. Here is an example:

/tp @e 10 64 255

This command  will teleport all entities to the coordinates X=10, Y=64, Z=255

You may also check for a specific quality of a Player or Entity

/tp @p[r=10] ~ ~10 ~

This command will teleport the nearest Player in a radius of 10 up 10 blocks.


  • You can spawn in a command block with cheats enabled by typing "/give (player name) 137" or /give (player name) "minecraft:command_block".
  • You can spawn mobs that are in the game, but cannot be spawned naturally. For Example, /summon Giant ~2 ~ ~ will summon a Giant Zombie 2 blocks away from the command block.
  • If you set the command to /testforblock x y z a open, where x,y,and z are the coordinates of the bottom half of a door, and a is the blockid for the door, by placing a comparator facing away from the command block, you can test if a door is open or shut.
  • Command blocks can hold an unlimited amount of text.
  • If you name a command block in an anvil, the name will appear when it's activated.
