Undoing a git rebase - git undo rebase

619 Asked by BenPHILLIPS in Devops , Asked on Apr 20, 2021

Does anybody know how to undo git rebase?

The only way that comes to mind is to go at it manually:

git checkout the commit parent to both of the branches
then create a temp branch from there
cherry-pick all commits by hand
replace the branch in which I rebased by the manually-created branch

In my current situation, this is gonna work because I can easily spot commits from both branches (one was my stuff, the other was my colleague's stuff).

However, my approach strikes me as suboptimal and error-prone (let's say I had just rebased with 2 of my own branches) then, how to undo git rebase?

Any ideas?

Clarification: I'm talking about a rebase during which a bunch of commits was replayed. Not only one.

The easiest way to undo git rebase is, find the head commit of a branch is using the following commands.

  git reflog

and to reset the current branch to it with -- hard option, if suppose old commit was HEAD@{1} in reflog then follow the commands

  git reset --hard HEAD@{1}

If you are using windows system then you need to quote it “HEAD@{1}”.

History of the old commit can find in

  git log HEAD@{1}

If you've not disabled per branch reflogs

  git reflog branchname@{1}

As rebase detaches the branch head before reattaching to the final head.
