![]() ![]() Rather than messing with all this, it's often easier to just rebase back to the branch you merged off of and leave the extra commits as pick. So HEAD^2~2 is the first grandparent of the second parent of HEAD. HEAD^2 selects the second parent of HEAD. If you want just two commits on the side branch, that's git rebase -i HEAD^2~2. HEAD^2 selects the second parent, which is the first commit in the branch. Using 'git merge', the result of our integration would look like this: Using 'git rebase', the end result looks quite different - especially because no extra merge commit will be created. HEAD^ is the first parent, same as HEAD~. Before we look at the exact steps that occur during a rebase, let's illustrate the differences between merge and rebase. That means HEAD, HEAD~1, and all the commits in the side branch. Git rebase -i HEAD~2 is really git rebase -i HEAD~2.HEAD so you're going to get all the commits reachable from HEAD excluding all the commits reachable from HEAD~2. ~ is a good way to move through history skipping over merged branches. An Example Scenario Let's take a simple scenario with the following two branches. However, it's not your only option: 'git rebase' offers another, slightly different way of integration. That is the left hand side of your graph. Using the 'git merge' command is probably the easiest way to integrate changes from one branch into another. rebase takes a series of commits (normally a branch) and replays them on top of another commit (normally the last commit in another branch). ~ indicates the first parent of a commit. git rebase is used to integrate changes from one branch into another. That argument is passed into git merge-base in order to determine the most recent shared commit between that branch, and the current branch.Merge commits have more than one parent commit. This alias is just a shell script, that is using an argument which refers to the parent branch. My typical flow is to pick the oldest commit (the one at the top), and set all other commits to f (or fixup). You can then use an interactive rebase to pick/reword/edit/squash/etc all commits in your branch, since it diverged from the parent branch. gitconfig: rbi = !sh -c \"git rebase -i `git merge-base $1 HEAD`\". If you instead want to rebase all the commits in your current branch, since the most recent commit it shared with its parent branch, you can add the following alias to. This is only a minor annoyance but it is an annoyance. The whole problem here is that you have to know which commit you have to refer to, either by its SHA, or HEAD~x, etc. The problem with rebasing from a known commit The problem with git rebase -i master is that you may have merge conflicts that you don't necessarily want to deal with at the moment, or you may fix a conflict in one commit, only to fix it again in another commit during the course of the rebase. ![]() The problem with rebasing from a different branch After starting the interactive rebase session, you’ll be presented with an editor window where Git lists a series of commits from the latest commit. This answer applies if you don't actually want to rebase on top of master, but you'd rather just squash all commits into one, since diverging from master. Which will show you all the commits on that branch, and piping to cat will disable the pager so you see the first commit immediately.ĮDIT: combining the above gives a fully automated solution: git rebase -i `git log master.other_feature -pretty=format:"%h" | tail -n 1`~ I'm sure there's some magic way to convince git to figure out the root of the tree automatically, but I don't know what it is.ĮDIT: That magic is this: git log master.other_feature | cat # However, if you remove everything, the rebase will be aborted. It is an integral part of several Git workflows, notably Git Flow. You can use it to clean up a feature branch before publishing or incorporate new commits from another branch. ![]() # If you remove a line here THAT COMMIT WILL BE LOST. Git Rebase is one of the most commonly used ways to rewrite commit history on a branch. # squash = use commit, but meld into previous commit # edit = use commit, but stop for amending Now that I know the root hash I can run this: git rebase -i 38965ed29d89a4136e47b688ca10b522b6bc335fĪnd my editor pops up with this and I can rearrange/squash/whatever as I please. ![]() Then run: git rebase -i įor example, I have a repository that I inspected using gitx: Use gitk (*nix), or gitx (OS X) or similar on other platforms, and have a look at which commit was the root of your branch. ![]()
