How to Undo a Commit in Git ?

  • Last Updated : 19 Oct, 2021

Basically, you did the last commit in your local repository and have not pushed back to the public repository or simply you want to change, basically, you do not want to do that commit so you wanted to undo the commit but in generic, there arise two cases where undo a commit is needed and possible sometimes as follows:

  1. Undo a commit From the local repository
  2. Undo a commit from the public repository

Case 1: Undo a commit from the local repository 

1.1 First check your all commits

#git log

Output: commits are just examples or sample commits

commit 2: second commit  
commit 1:  First commit  

Perception drawn are as follows:



  • commit 2 is the commit you want to undo, the current head is here
  • commit1 is the first commit where you want to go after undo

1.2 To restore everything or undo all the changes we have to reset the commit.

#git reset --soft HEAD^      
#git reset --hard HEAD^  

Note: 

  • soft is used if you want to keep your changes
  • hard is used if you don’t want to keep your changes

1.3 To check your commit is reset or not

#git log

Output:  

commit 1: First commit   
//undo the second commit, now head is at first or previous commit

 One can clearly see last commit (i.e. second commit) is removed.

Case 2: Undo a commit from the public repository

Now if we have already made your commit public then you will have to create a new commit which will “revert” the changes you made in your previous commit (current HEAD) then do follow the certain commands:

  • Reverting changes
  • Checking all commits to see the list of commits

2.1 revert your changes 

#git revert HEAD  

We are now ready for your new commit in order to restore the file that we accidentally have remove with the below command as follows:

#git commit -m 

2.2 Now check your all commits to see the list of commits

#git log

Output:

commit 3: restoring the file that we accidently remove  
commit 2: removing a file we don't need 
commit 1: Needed file 

Now we can revert your last commit.

Also do note that we use the command below specified to undo the last commits in git where the head is a pointer pointing to the last commit in our branch 

git reset HEAD~<no-of-commits>
