Steps to reprocedure1. Place a command block2. But in a testfor command3. See how it is a "unknown command".
You're seeing the output of the previously run command (therefore the text field is captioned with "Previous Output")Fire the command block and after that you'll see the output of testfor
You've got to put a / before testfor
Try /testfor
/ is not necessary in command blocks.
