How to undo git commit

There are three ways to undo Git commits: use git reset to undo the commit directly; use git revert to create the opposite new commit; use interactive rebase to modify the commit history and skip unwanted commits.

How to undo Git's submission

In Git, submitting code changes is an operation of saving a snapshot of your code into your code history. However, sometimes you may make unnecessary submissions or need to revoke them. This article will explain how to undo Git commits.

Method 1: Use git reset

This is the easiest and straightforward way:

 <code>git reset <commit-ish></commit-ish></code>

Where <commit-ish></commit-ish> is the commit hash or commit flag you want to undo the commit (for example, HEAD~1 means the previous commit).

Method 2: Use git revert

The git revert command creates a new commit that is opposite to the commit you want to revoke. This is often used to preserve the history of commits while undoing changes to the code base.

 <code>git revert <commit-ish></commit-ish></code>

Method 3: Use interactive rebase

Interactive rebase allows you to modify the commit history. Start the interactive rebase with the following command:

 <code>git rebase -i <upstream></upstream></code>

Where <upstream></upstream> is the branch you want to reassociate the branch with. In the editor, you can select the commit you want to undo and mark it as the commit you want to skip with the following command:

 <code>s <commit-ish></commit-ish></code>

Then, save and exit the editor. The rebase command will rewrite the history, skipping the commits marked as being skipped.

Things to note

• Revoking a commit may result in missing code changes. It is recommended to create a backup before revoking the submission.
• If the commit has been pushed to the remote repository, it cannot be revoked.
• Do not revoke the commit after other developers pull the commit.
