Yadayada, 1) wrong site (should belong to StackOverflow), 2) poor question, 3) you won't get full source code here, because people want so see that you have put at least some effort into your question (like formatting it properly). – slhck Mar 31 '11 at 7:11
grep <number> <file> -C 4 | head -n 1 – Sirex Mar 31 '11 at 8:40
