Undo a commit that hasn’t been push yet

If you made some mistakes in a commit, you can redo it in a new commit using --amend option. Just fix your mistakes, stage(add) them and make a new commit as below:

# Redo the last commit.
# --amend, replace the last commit with a new one.
$ git commit --amend

If above solution does not suit you, reset can be used to just undo the commit (be careful to use reset):

# Discard the last commit. The commit's modifications in working tree are kept.
$ git reset HEAD~

# Discard the last commit. The commit's modifications in staging area are kept.
$ git reset --soft HEAD~

# Discard the last commit. The commit's modifications in working tree are not kept.
$ git reset --hard HEAD~

Undo a commit that has been pushed

If a commit has been pushed to the remote repository, changing the history in the remote repository is not a good idea. You can let Git to make a new commit which reverses the modifications in the last commit.

git revert command works for you :

# Reverse a commit.
$ git revert -m 1 HEAD

Afterwards, push it to the remote repository again.
