Answer 1

Now, according to your words " no need to maintain order/sequence .just insertion is required in any row of CSV ", simple cat command would be enough:

 cat input.csv >> first.csv

---

Final first.csv contents:

11-AUG-17,2,85,18120.4
11-AUG-17,4,112,2920
11-AUG-17,5,23,4181.92
11-AUG-17,6,284,74767.86
11-AUG-17,3,0,0
11-AUG-17,8,0,0
