I wanted to merge in some changes from another repo so I added the remote, fetched and merged. But I did not think that the commits of the other branch would be added.
I backed one commit from my merge and manually added the changed files and pushed that commit.
So now I have two disconnected commit trees in one branch. Something like this:
A-B-C-D-master
1-2-3-4
And I just want to remove the 1-2-3-4 commits. I don't care about history or any child/parent commits or the files.
I want to keep the A-B-C-D commits with all history.
I have tried:
git reflog expire --expire-unreachable=now --all
git gc --prune=all --aggressive
git rebase [hash]
But nothing seems to work.
