Code:
awk -F, '{
  fn[f = $1 ".txt"]++ || c++ 
  if (c >= l) {
    for (F in fn) close(F)
    c = x
    }
  print >> f
  }' l=10 infile

Set l to the desired value (the # of open files).
thanks it's working well and also very fast. never think it's can be done by single line awk. i want to know also how to calculate the number of record base on value on column 1 and 2 , so the data after i extract is

Code:
8,7282012,343
7,7282013,0
6,7282012,0
6,7282012,0
6,7282012,0
6,7282012,0
8,7282012,277

the output that i want is
Code:
8,7282012,2
7,7282013,1
6,7282012,4

thanks in adv
