With the increasing popularity of modern software development, Git has become one of the most commonly used version control tools among developers. The powerful functions of Git help developers manage and collaborate on development projects more conveniently and efficiently. However, in the process of using Git, sometimes we accidentally delete or modify some important files or code. At this time, we need to restore the files or code in the Git repository. Below, this article will introduce the steps of how to restore files or code in Git.

1. How to restore files in Git?

  1. If you already know the name of the deleted file, you can restore the file in the local warehouse through the following command:
$ git checkout -- <filename>
Copy after login

In this command, -- represents the end of the parameter, <filename> is the name of the file to be restored. When using this command, Git will start from Pull the latest version of the file from the local repository and restore it to the staging area.

  1. If you need to restore the historical version of a file, you can use the following command:
$ git checkout <commit-hash> -- <filename>
Copy after login
Copy after login

In this command, <commit-hash> is the hash value of the historical version of the restored file, <filename> is the file name. When using this command, Git will pull back the specified version of the repository and restore the files specified by that version to the local repository.

2. How to restore code in Git?

  1. If you just want to see the difference between the deleted code before and after modification, you can use the following command:
$ git diff <commit-hash-1> <commit-hash-2>
Copy after login

In this command, <commit-hash-1> and <commit-hash-2> are the hash values ​​of the two versions to be compared, use When running this command, Git will compare the code differences between the two versions and output these differences in the terminal.

  1. If you need to restore the historical version of a file, you can use the following command:
$ git checkout <commit-hash> -- <filename>
Copy after login
Copy after login

In this command, <commit-hash> is the hash value of the historical version of the restored file, <filename> is the file name. When using this command, Git will pull back the specified version of the repository and restore the files specified by that version to the local repository.

3. How to restore all codes in Git?

Sometimes, we not only need to restore a single file or code, but also need to restore the entire warehouse. At this time, the easiest way is to clear the local warehouse and pull the remote warehouse again. This process can be completed by following the following steps:

  1. Clear the local warehouse:
$ git reset --hard HEAD
Copy after login

In this command, --hard HEAD means reset to current version.

  1. Pull the remote repository:
$ git pull origin <branch-name>
Copy after login

In this command, <branch-name> is the name of the branch you want to pull.

After you execute the above command, your local code base will be restored to the latest version. It should be noted that clearing the local repository will delete all uncommitted code modifications, so please use it with caution.

In this article, we introduce the steps to restore files and code in Git. By mastering these commands, you can more quickly retrieve deleted or modified code and continue moving forward with your project. Of course, in order to ensure the security of your code, we recommend following best practices when using Git and backing up your code base regularly.
