Hi everyone,

Here is my problem:

For my research I need to work with files of 700 Mb. I get "Segmentation Fault" error and while my code works for smaller files, I assumed the large size of the file leads to this problem. That is why I think that I need to split the files into smaller ones.

A simplified version of a sample file looks like:

[TEX]

Line #

1 Day 1 Month 1 1

2 Day 2 Month 2 1

3 Day 3 Month 3 1

4 Day 4 Month 4 1

5 Day 5 Month 5 1

6 Day 6 Month 6 1

7 Day 7 Month 7 1

8 Day 8 Month 8 1

9 Day 9 Month 9 1

10 Day 10 Month 10 1

11 Day 11 Month 11 1

12 Day 12 Month 12 1

13 Day 1 Month 1 2

14 Day 2 Month 2 2

15 Day 3 Month 3 2

16 Day 4 Month 4 2

17 Day 5 Month 5 2

18 Day 6 Month 6 2

19 Day 7 Month 7 2

20 Day 8 Month 8 2

21 Day 9 Month 9 2

22 Day 1 Month 10 3

I want to store data related to each number in a separate file. In other words I want to collect data in line 1 to 12 into one file, and from 13 to 21 in another and so on. I am ale to find the line numbers where the file needs to be cut. But I do not know where to go from there. I would appreciate any suggestion.
