Command Block

“	If you mostly play survival mode, and you're thinking "that sounds a lot like cheating", then you're right – which is why command blocks aren't available in survival mode. They're a feature that we built specifically for creative mode, and for adventure mode mapmakers. Jeb announced their existence in a tweet in July 2012, and they were added to the game in version 1.4.2 – the Pretty Scary Update, which also added spooky anvils, creepy flowerpots and terrifying carrots on sticks.	„

Background

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 and in custom maps.

Command Blocks are not available in the Creative inventory. It can either be obtained by using the pick block control, or by using various commands, such as /give @s command_block, or /setblock ~ ~ ~ minecraft: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 also cannot be broken in Survival mode without operator permissions, are not flammable, cannot be moved by pistons, and have the same blast resistance as bedrock.
