I mean the output should be "the line I need to get". The example wasn't originaly quoted correctly (meantime I have corrected it). But if I understand your proposal well, only one more ';n' should...

Hi everybody,...

thanx for your posts, but your solution with grep is not universal as limited by -A option.
