GIT: How do I rebase nested branches?

Question

My structure looks like this->

master
  develop 
    project
      
        

I work on the task_number

Answer 1

In this way, all of the commits on project are sprints, and all of the commits on sprint are task

You don't need to do it this way. simply use the pull request you have created since all the code will be merged into develop at the end.

As soon as you open the pull request you can also delete your local branches and keep only the latest one for future changes if you will need any.
