Undo a commit & redo
$ git commit -m "Something terribly misguided" # (0: Your Accident)
$ git reset HEAD~ # (1)
# === If you just want to undo the commit, stop here! ===
[ edit files as necessary ] # (2)
$ git add . # (3)
$ git commit -c ORIG_HEAD # (4)
git resetis the command responsible for the undo. It will undo your last commit while leaving your working tree (the state of your files on disk) untouched. You'll need to add them again before you can commit them again.- Make corrections to working tree files.
git addanything that you want to include in your new commit.- Commit the changes, reusing the old commit message.
resetcopied the old head to.git/ORIG_HEAD;commitwith-c ORIG_HEADwill open an editor, which initially contains the log message from the old commit and allows you to edit it. If you do not need to edit the message, you could use the-Coption.
Alternatively, to edit the previous commit (or just its commit message), commit --amend will add changes within the current index to the previous commit.
To remove (not revert) a commit that has been pushed to the server, rewriting history with git push origin main --force[-with-lease] is necessary. It's almost always a bad idea to use --force; prefer --force-with-lease instead, and as noted in the git manual:
You should understand the implications of rewriting history if you amend a commit that has already been published.

You can use git reflog to determine the SHA-1 for the commit to which you wish to revert. Once you have this value, use the sequence of commands as explained above.
HEAD~ is the same as HEAD~1. The article What is the HEAD in git? is helpful if you want to uncommit multiple commits.

HEAD~ is the same as HEAD~1. The article What is the HEAD in git? is helpful if you want to uncommit multiple commits.
Undoing a commit is a little scary if you don't know how it works. But it's actually amazingly easy if you do understand. I'll show you the 4 different ways you can undo a commit.
Say you have this, where C is your HEAD and (F) is the state of your files.
(F)
A-B-C
↑
master
Option 1: git reset --hard
You want to destroy commit C and also throw away any uncommitted changes. You do this:
git reset --hard HEAD~1
The result is:
(F)
A-B
↑
master
Now B is the HEAD. Because you used --hard, your files are reset to their state at commit B.
Option 2: git reset
Maybe commit C wasn't a disaster, but just a bit off. You want to undo the commit but keep your changes for a bit of editing before you do a better commit. Starting again from here, with C as your HEAD:
(F)
A-B-C
↑
master
Do this, leaving off the --hard:
git reset HEAD~1
In this case the result is:
(F)
A-B-C
↑
master
In both cases, HEAD is just a pointer to the latest commit. When you do a git reset HEAD~1, you tell Git to move the HEAD pointer back one commit. But (unless you use --hard) you leave your files as they were. So now git status shows the changes you had checked into C. You haven't lost a thing!
Option 3: git reset --soft
For the lightest touch, you can even undo your commit but leave your files and your index:
git reset --soft HEAD~1
This not only leaves your files alone, it even leaves your index alone. When you do git status, you'll see that the same files are in the index as before. In fact, right after this command, you could do git commit and you'd be redoing the same commit you just had.
Option 4: you did git reset --hard and need to get that code back
One more thing: Suppose you destroy a commit as in the first example, but then discover you needed it after all? Tough luck, right?
Nope, there's still a way to get it back. Type this
git reflog
and you'll see a list of (partial) commit SHAs (that is, hashes) that you've moved around in. Find the commit you destroyed, and do this:
git checkout -b someNewBranchName shaYouDestroyed
You've now resurrected that commit. Commits don't actually get destroyed in Git for some 90 days, so you can usually go back and rescue one you didn't mean to get rid of.

Is there a way to remove all local commits while keeping the changes?
How do I undo the last commit without losing changes?
I would like to organize my PR after my feature is done by removing all of my 'work in progress'-commits and creating new commits that group files to improve the readability of my PR.
I have tried using git reset, but that only unstages changes that have been added using git add . & all files that are already committed seem to be out of reach.
