Remove an old Git commit from a branch without using a reverse patch? [duplicate]

Answer 1

Use interactive rebase. For example, to go back 5 commits:

git rebase -i HEAD~5

Then in the editor which pops up, delete the line containing the commit you want to remove.

Answer 2

Interactive rebase works, but to do it with just one command:

git rebase --onto B C

Still see the comments on the "interactive rebase" answer. They apply here, too.
