A command block is a block that can execute commands. Because it cannot be obtained or edited in Survival mode without cheats, it is primarily used on multiplayer servers, in Creative worlds, and custom maps.
An impulse command block is the default block type; it executes only once when activated.
A chain command block executes every time when triggered.
A repeating command block executes every game tick as long as it is activated.
In Java Edition, command blocks are available in the Creative inventory under the "Operator Utilities" tab, if the "Operator Items Tab" setting in the "Controls" Options tab is set to "ON". Across both Java and Bedrock editions, they can either be obtained by using the pick block control, or by using various commands, such as /give @s minecraft:command_block, or /setblock ~ ~ ~ command_block.
Just like other blocks that can store NBT data, using pick block + CTRL copies the command and options inside the command block. This allows it to be placed elsewhere without having to re-enter the data inside.
Command blocks are not flammable, and have the same blast resistance as bedrock. Command blocks, structure blocks, and jigsaw blocks cannot be mined in Survival.
Command blocks can be placed by a non-operator player.
A command block can execute commands when activated by redstone power. It always has permissions of 2 level[Java Edition only]/1 level[Bedrock Edition only], so it can be used to allow a specific use of a command by players who can't use that command in general (for example, allowing anyone to obtain a specific item with /give without allowing everyone to /give themselves whatever they want).
A command block has an orientation that determines the chain command block to activate, and the blocks to be checked to see if a command block in "Conditional" mode executes.
ID
: : 1.ID of block's direct item form, which is used in savegame files and addons. 2.a b c Available with /give command. 3.a b c The block's direct item form has the same id as the block.
Block data
A command block has a block entity associated with it that holds additional data about the block. : •Block entity data •Tags common to all block entities •auto: 1 or 0 (true/false) - Allows to activate the command without the requirement of a redstone signal. •Command: The command to issue to the server. •conditionMet: 1 or 0 (true/false) - Indicates whether a conditional command block had its condition met when last activated. True if not a conditional command block. •CustomName: Optional. The name JSON text component of this command block, replacing the usual '@' when using commands such as /say and /tell. •LastExecution: stores the tick a chain command block was last executed in. •LastOutput: The last line of output generated by the command block. Still stored even if the game rule commandBlockOutput is false. Appears in the GUI of the block when right-clicked, and includes a timestamp of when the output was produced. •powered: 1 or 0 (true/false) - States whether or not the command block is powered by redstone or not. •SuccessCount: Represents the strength of the analog signal output by redstone comparators attached to this command block. •TrackOutput: 1 or 0 (true/false) - Determines whether the LastOutput is stored. Can be toggled in the GUI by clicking a button near the "Previous Output" textbox. Caption on the button indicates current state: "O" if true, "X" if false. •UpdateLastExecution: 1 or 0 (true/false) - Defaults to true. If set to false, loops can be created where the same command block can run multiple times in one tick.
