More on scan: extra field at end of line

Hi,

I see that Prof Ripley propose to pre-process the file using sed. I saw that
to do so he used "pipe". I look for it on my system (see below) and the
function doesn't seem to be available. Since I have sed from cygwin32 I
wonder if there would a way to use it in a similar fashion as proposed here?

Thanks

YG
