How to undo git commit --amend done instead of git commit

Question

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

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

You can always split a commit  From the manual   Start an interactive rebase with git rebase -i commit   where commit is the commit you want to split  In fact  any commit range will do  as long as it contains that commit  Mark the commit you want to split with the action  edit   When it comes to editing that commit  execute git reset HEAD   The effect is that the HEAD is rewound by one  and the index follows suit  However  the working tree stays the same  Now add the changes to the index that you want to have in the first commit  You can use git add  possibly interactively  or git-gui  or both  to do that  Commit the now-current index with whatever commit message is appropriate now  Repeat the last two steps until your working tree is clean  Continue the rebase with git rebase --continue

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

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

Maybe can use git reflog to get two commit before amend and after amend   Then use git diff before commit id after commit id  gt  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

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  lt SHA BEFORE THE AMMEND gt   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  lt your-branch gt  --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

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

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

Simple Solution Solution Works Given  If your HEAD commit is in sync with remote commit   Create one more branch in your local workspace  and keep it in sync with your remote branch  Cherry pick the HEAD commit from the branch  where git commit --amend  was performed onto the newly created branch   The cherry-picked commit will only contain your latest changes  not the old changes  You can now just rename this commit
