Thanks for further explanation! Yes, the naming is confusing, but I think it is difficult to find a better name to those commands that are internal of nsh. At this point calling them built-in like in Linux will make things more confuse because the "external" apps are already called built-in. It is something that everyone using NuttX get grasped too fast. BR, Alan
