How to organize fragments without interaction in git?

I know I can add chunks using any of the following commands

git add -i
git add --patch
git add --edit

      

        
        
        
      

    

But I can get all the chunks for the file

git --no-pager diff file1 > /tmp/stageme

      

        
        
        
      

    

I see three chunks, I only want the first and last chunks, so I delete the second chunk of the file /tmp/stageme

How can I execute these chunks in a command? I mean, how can I create information from /tmp/stageme

?
