Thanks for the kind words Alan. I'm not sure about a bunch of that sed line. It must have come from a google search. But the parts I do recognize (because they work in sed and in vi) are the s/.../.../g parts. Those are search and replace statements. The second one "s/[a-zA-Z&;]//g" looks for all alpha characters and replaces them with nothing. So if the grep line returns "Saskatoon Crazy Heavy Snow -40C" that search and replace will strip out the alpha characters leaving only -40. Have a great day, Robert
