Add file to original commit without creating a new commit

Question

I made 10 commits and each commit has already been moved to the central repository. Suppose I committed a commit, for example.

C1-C2-C3-C4-C5

where C5 was my last latch, and all the latches were pressed. I’m a branch master. I want to delete the history and want to keep the last commit in git logs. I don't want anyone to be able to reset reset to any previous commit or push.

someone told me to use git rebase -i head~4, but I want to be clear before introducing it.

I have the following commands

git checkout --orphan newB
git add -A
git commit
git branch -D master
git branch -m master
git push

and after these commands above my git graph becomes according to the given image below

The current graph of my repository is as follows

. . git rebase

$ git rebase -i head~5
fatal: Needed a single revision
invalid upstream head~5

Answer 1

, upstream. ( , , - , , .)

--root, , , .

:

% git log --oneline
072c8fc Modification 3 to master
9bdb3a2 Modification 2 to master
45f0758 Modification 1 to master
96da320 Initial revision

upstream 96da320 ( HEAD~3) . , HEAD~4, , , , .

, --root:

% git rebase -i --root

rebase script :

pick 96da320 Initial revision
pick 45f0758 Modification 1 to master
pick 9bdb3a2 Modification 2 to master
pick 072c8fc Modification 3 to master

Answer 2

git rebase -i head~5 git rebase -i head~4
