How the /execute Command Works
The /execute command lets you modify the context before running another command. You can change who runs it (as), where it runs (at, positioned), which dimension (in), or add conditions (if, unless). The final run subcommand specifies what to execute.
Common /execute Patterns
Run as every player at their position
/execute as @a at @s run say Hello from my position!
Conditional: only if a block exists
/execute if block ~ ~-1 ~ minecraft:diamond_block run give @s minecraft:diamond 1
Run in the Nether
/execute in minecraft:the_nether positioned 0 64 0 run setblock ~ ~ ~ minecraft:glowstone
Negated condition
/execute unless entity @a[distance=..5] run say No players nearby
