#Git undo commit before push how to

When force pushing on GitHub, the UI shows information about the force-pushes that have occurred: This tells us that the last push to the remote was 5e2791da4 and it overrode c574fceb1, so c574fceb1 is the one we need to restore to. $ git reflog refs/remotes/origin/update/wiremock-docs If we're using the branch update/wiremock-docs, on the Git remote origin, then we can use git reflog like so: If you don't have that output any more, we can fortunately use git reflog to recover this. This means that the left-hand side commit hash, c574fceb1 is the one we need to restore to. Git is telling us that it's just force pushed the branch update/wiremock-docs to commit 5e2791da4, when before it was c574fceb1. + c574fceb1.5e2791da4 update/wiremock-docs -> update/wiremock-docs (forced update) Total 5 (delta 4), reused 0 (delta 0), pack-reused 0 Let's say that the output they see is: Enumerating objects: 9, done.

Unfortunately, without a practical example, I can't share too much about how to do that. Note that these are from the viewpoint of your local machine being the one who's pushed it - if trying to recover someone else's, you may need to git fetch -all at some point, and play around with the commands. In the spirit of blogumentation, I thought I'd document it for future me. One of my colleagues recently got in touch with me to say that they'd force pushed to the wrong branch, and needed a hand to recover things if possible.įortunately, this is something I've had to do numerous times - because I've got it wrong myself - so I was able to help. I really like telling a descriptive story with our Git commit history, and spend a fair bit of time making sure that the history provides the right level of information.īecause writing Git commit messages, and having a good commit history, leads to needing to rewrite Git history, I'm quite comfortable with git rebase and rewriting Git history safely.
