Hi, I need to extract from the file:

second

I don't really understand what do you want to match. I would not use grep, but one of the following:

tail -2 file         # to get last two lines
head -n +2 file      # to get all but first line
sed -e '2,3p;d' file # to get lines from second to third

(not sure how standard it is, it works in GNU tools for sure)
