Glad you were able to solve it by yourself.
Not only can you insert, you can append and change also.

Also, there is a way you can avoid the last line (the move command).
Do a little more research on "w" option. Of course, it has its own limitations. But if the file size is really big, then you save a lot of time and resources.
