How do I get those line in green deleted as i do not know when is the last 'calls' line?
And how do I loop to remove those lines in all the txt files?

Anyone can help?

Let me get this straight. You want to delete the lines in green. But you don't know which lines these are until you come across "the last pattern"? And then you want to delete the lines above it? So what is special about the line that tells you that you need to delete it and the other lines?
