What does @$ mean in makefile?

Question

What does @$ mean in the below make recipe ?

@$(OBJCOPY) -S --set-section-flags .bss=alloc,contents -O binary $(BINARY).elf $(BINARY).bin

Thanks

The @$ is not a single token. It's two different tokens: @ followed by $. You could a space between them if that makes it clearer for you... make doesn't care. — MadScientist, Commented Nov 12, 2021 at 17:10

The @ sign in the beginning of the recipe command means "do not echo the command".

The $(OBJCOPY) in your recipe command means "substitute here the value of the OBJCOPY variable".
