Tools I got a start on this
But, I will need some awk help (or to think a little clearer after eating lunch)

Code:
> cat big_file4
a stuff to 1 file
b stuff to 2 file
c stuff to 3 file
a stuff to 1 file
b stuff to 2 file
c stuff to 3 file
a stuff to 1 file
b stuff to 2 file
c stuff to 3 file
d stuff to 4 file
a stuff to 1 file
b stuff to 2 file
c stuff to 3 file
a stuff to 1 file
b stuff to 2 file
c stuff to 3 file
a stuff to 1 file
b stuff to 2 file
c stuff to 3 file
d stuff to 4 file

What I initially wrote does not capture the file line of text - and where I think I need some HELP!
Code:
> cat -n big_file4 | awk '{printf "%1s %-15s \n", substr($1,length($1),1), $2}'
1 a               
2 b               
3 c               
4 a               
5 b               
6 c               
7 a               
8 b               
9 c               
0 d               
1 a               
2 b               
3 c               
4 a               
5 b               
6 c               
7 a               
8 b               
9 c               
0 d

Because from here, my theory is that

Code:
grep "^[147] " <infile >outfile_a
grep "^[258] " <infile >outfile_b
grep "^[369] " <infile >outfile_c
grep "^[0] " <infile >outfile_d

May need to cut before writing to each output.
