Indeed, I forgot the double quotes. That works:

setenv PATH "${HOME}/bin:${PATH}"

I confused the message like a length limitation and not for the number of input arguments.

Why do you say both? I don't add /usr/bin anywhere.

Care to explain? How else can I add in the path custom personal commands?
