How to deal with files deleted by 'git pull' command

Git is a very powerful version control tool that makes team development more convenient and efficient. When using Git, the command to pull code - "git pull" is often used. This command is usually used in scenarios such as updating code and getting the latest code, but you may encounter a problem: when you use the "git pull" command to pull the code, you find that a file is missing. What should you do in this situation? This article will detail how to deal with files deleted by the "git pull" command.

1. Deletion situation

When using the "git pull" command to pull the code, if a file is found to be deleted locally, it is most likely because the file is in the remote code The library has also been deleted. At this point, you need to clarify the following two questions:

• Is the file indeed deleted?
• If it was indeed deleted, do you really need the file?

If you determine that the file should not have been deleted, then you need to retrieve it.

2. Retrieve deleted files

After executing the "git pull" command, if a file is found to have been deleted, you can retrieve the file through the following operations:

2.1 Restore files to the latest version

When using the "git pull" command to pull the code, you can use the following command to force overwriting of local content:

git fetch --all  
git reset --hard origin/master

These two lines of commands can force Overwrite local files with the latest version of the remote code base. However, it should be noted that this will cause the local uncommitted code to be lost. Please back up the local code before operation.

2.2 Retrieve the file from historical versions

If you have submitted the file and it has been deleted in the remote code base, you can follow the following steps to retrieve the file:

1. Use the following command to view the historical version of the file:

   git log -- <filename></filename>

2. Select the historical version you need to restore, and use the following command to restore the version:

   Among them, is the historical version number you selected, is the name of the file you need to restore.

3. Avoid files being accidentally deleted

It is very important to avoid files being accidentally deleted when using Git. Here are some common methods:

3.1. Using Git hooks

Using Git hooks can automatically perform some operations, such as checking file status before submitting code to prevent accidental deletion of files. For details, please refer to [Git official documentation](https://git-scm.com/book/zh/v2/custom-Git-Git-hook).

3.2. Use Git aliases

You can configure aliases in Git, which can avoid some repeated commands. For example, configuring the following alias can avoid accidentally running the "git push --force" command:

git config --global alias.force-push 'push --force-with-lease'

3.3. Using Git LFS

Git LFS is a large file version control tool developed by GitHub that supports Large files are tracked and managed. When using Git LFS, even large files can be successfully versioned and are not easily deleted by accident.

4. Summary
