CUDA: commands don't work after nvcc

I am trying to compile a .cu program with nvcc and after every time I try and compile in Unix, my commands no longer work. I get an error:

'command': command not found.

Why is that? I have to logout/exit after each time I compile.

[EDIT] I actually found that setting the path: setenv PATH /usr/local/cuda/bin causes the problem. Commands like: ls, pico, cd, etc. do not work. I can exit and logout

You don't want to do setenv PATH /usr/local/cuda/bin You want to do setenv PATH $PATH:/usr/local/cuda/bin or some variant of that like setenv PATH $PATH":/usr/local/cuda/bin" When you do it your way, you are replacing your existing PATH definition, so you lose the command path to all those other commands. Try echo $PATH to see what it looks like before you change it. You want to add to it, not replace it.

You are deleting your path, you need to append to the PATH instead of overwriting it.

setenv PATH ${PATH}:/usr/local/cuda/bin
