Hi,  Let us say I have a text file of a million lines, and I want to cut it into smaller (10K lines) ones.  How to do this? I have tried a few ways, none I think is lazy (I mean not reading the file all at the start).

I would just seek to the approximate chunk boundaries (10k, 20k, etc) and the read forward until hitting a newline. Cheers, Johan
