split file problem

Hi All,

I have a parent file with 10 million records. I want to split the parent file in to child files.

Each child file contains 5000 records.

I am using the following command for splitting:

split -5000 parentfile.txt childfile.1

It will split the Parent file as childfile.1aa, childfile.1ab, ... childfile.1zz
It will split only 676 files (=> 3.38 million records only) .

I am not able to split the parentfile into childfile (More than 676 files) at single shot. Please provide your suggestions for splitting.


Regards
Hanuma
