No, that didn't work either.

There is no variable 'z' in the ctl file, but there is 'zg'. 'd zg' should display geopotential height.

Here is the output of what I tried. Right off it seems to fail:

If you mean the tutorial, yes it does work. If you mean other example online, those example might be openGrADS example, which is based on GrADS itself. Therefore it the tutorial is not working, and you are absolutely sure you can't open the tutorial file itself, and not mistaking the path or anything, I would say you have a faulty installation.
