I accidentally amended my previous commit. The commit should have been separate to keep history of the changes I made to a particular file.
Is there a way to undo that last commit? If I do something like git reset --hard HEAD^
, the first commit also is undone.
(I have not yet pushed to any remote directories)
What you need to do is to create a new commit with the same details as the current HEAD
commit, but with the parent as the previous version of HEAD
. git reset --soft
will move the branch pointer so that the next commit happens on top of a different commit from where the current branch head is now.
# Move the current head so that it's pointing at the old commit
# Leave the index intact for redoing the commit.
# HEAD@{1} gives you "the commit that HEAD pointed at before
# it was moved to where it currently points at". Note that this is
# different from HEAD~1, which gives you "the commit that is the
# parent node of the commit that HEAD is currently pointing to."
git reset --soft HEAD@{1}
# commit the current tree using the commit details of the previous
# HEAD commit. (Note that HEAD@{1} is pointing somewhere different from the
# previous command. It's now pointing at the erroneously amended commit.)
git commit -C HEAD@{1}
You can always split a commit, From the manual
Maybe can use git reflog
to get two commit before amend and after amend.
Then use git diff before_commit_id after_commit_id > d.diff
to get diff between before amend and after amend.
Next use git checkout before_commit_id
to back to before commit
And last use git apply d.diff
to apply the real change you did.
That solves my problem.
You can do below to undo your git commit —amend
git reset --soft HEAD^
git checkout files_from_old_commit_on_branch
git pull origin your_branch_name
====================================
Now your changes are as per previous. So you are done with the undo for git commit —amend
Now you can do git push origin <your_branch_name>
, to push to the branch.
None of these answers with the use of HEAD@{1}
worked out for me, so here's my solution:
git reflog
d0c9f22 HEAD@{0}: commit (amend): [Feature] - ABC Commit Description
c296452 HEAD@{1}: commit: [Feature] - ABC Commit Description
git reset --soft c296452
Your staging environment will now contain all of the changes that you accidentally merged with the c296452 commit.
Simple Solution Solution Works Given: If your HEAD commit is in sync with remote commit.
The cherry-picked commit will only contain your latest changes, not the old changes. You can now just rename this commit.
If you have pushed the commit to remote and then erroneously amended changes to that commit this will fix your problem. Issue a git log
to find the SHA before the commit. (this assumes remote is named origin). Now issue these command using that SHA.
git reset --soft <SHA BEFORE THE AMMEND>
#you now see all the changes in the commit and the amend undone
#save ALL the changes to the stash
git stash
git pull origin <your-branch> --ff-only
#if you issue git log you can see that you have the commit you didn't want to amend
git stash pop
#git status reveals only the changes you incorrectly amended
#now you can create your new unamended commit
Checkout to temporary branch with last commit
git branch temp HEAD@{1}
Reset last commit
git reset temp
Now, you'll have all files your commit as well as previous commit. Check status of all the files.
git status
Reset your commit files from git stage.
git reset myfile1.js
(so on)
Reattach this commit
git commit -C HEAD@{1}
Add and commit your files to new commit.
Possibly worth noting that if you're still in your editor with the commit message, you can delete the commit message and it will abort the git commit --amend
command.
use the ref-log:
git branch fixing-things HEAD@{1}
git reset fixing-things
you should then have all your previously amended changes only in your working copy and can commit again
to see a full list of previous indices type git reflog
Almost 9 years late to this but didn't see this variation mentioned accomplishing the same thing (it's kind of a combination of a few of these, similar to to top answer (https://stackoverflow.com/a/1459264/4642530).
Search all detached heads on branch
git reflog show origin/BRANCH_NAME --date=relative
Then find the SHA1 hash
Reset to old SHA1
git reset --hard SHA1
Then push it back up.
git push origin BRANCH_NAME
Done.
This will revert you back to the old commit entirely.
(Including the date of the prior overwritten detached commit head)
Find your amended commits by:
git log --reflog
Note: You may add --patch
to see the body of the commits for clarity. Same as git reflog
.
then reset your HEAD to any previous commit at the point it was fine by:
git reset SHA1 --hard
Note: Replace SHA1 with your real commit hash. Also note that this command will lose any uncommitted changes, so you may stash them before. Alternatively, use --soft
instead to retain the latest changes and then commit them.
Then cherry-pick the other commit that you need on top of it:
git cherry-pick SHA1
