But this isn't *silent* correction. The shell tells you where it's putting you when it does this, same as in a 'cd' that happens via $CDPATH. Admittedly, you have to be paying attention, but Unix has always demanded that of its users. Note that I am not arguing with the idea that silent correction is bad; I'm merely pointing out that this is not an instance of that. Thanks, Arnold
