If you are a web developer or a software engineer, it is very likely that you are pushing a lot of commits to your Git repository every day. Sometimes you committed some files that should not be pushed to your Git repository or you may want to perform additional changes before issuing the commit. Here is how you can revert a commit to GIT. 

How to Access the Last Commit

To get the hash of the specific commit you can run 

git log

You can simplify the output by running

git log --online

To test a specific commit (e.g.: <before last commit hash>), that you think has the last working version, you can type the following: 

git checkout <commit hash>

How to Revert or Undo the Last Commit

You can undo or revert the last commit by using the commit hash that you get from the git log command:

git revert <commit hash>

This command will create a new commit with the “Revert” word in the beginning of the message.

You can check the status of your repository after this command 

git status 

You’ll notice that you have the HEAD detached at the commit you tested before.

To fix this and attach back the HEAD to your working repository, you should check out the branch you are working on:

git checkout <current branch>

Common Options

-e
--edit

With this option, git revert will let you edit the commit message prior to committing the revert. This is the default if you run the command from a terminal.

--no-edit

With this option, git revert will not start the commit message editor.

-n
--no-commit

Passing this option will prevent git revert from creating a new commit that inverses the target commit. Instead of creating the new commit, this option will add the inverse changes to the Staging Index and Working Directory. These are the other trees Git uses to manage state the state of the repository.
