The first million lines goes to file1 and the remaining lines to file2:

Code:
awk 'NR<1000001{print $0 > "file1";next}{print $0 > "file2"}' file

It's not allowed to bump up questions! Please read the rules.

Have you tried the solution above? Maybe you can also use the commands head and tail. Read the regarding manpages.
