App - Script

I’m currently working on level 8 right now.

I found a way to execute a script directly with the help of the available command but I can’t start a new shell over that (results in empty screen, like a text editor).
So I thought it would be a good idea to compile a binary file which opens a shell with rws rights. But this only results in uid=level7 and euid=level8 and seems to be a dead end.

Is there something I have overlooked ? Am I going into the right direction or should I take a step back and try again from the beginning ?

EDIT :
I managed to solve it !
For others who may need some advice : I was not going into the right direction. Start over from the beginning and keep in mind that copying files locally isn’t the same as copying files on localhost..
