How to roll back cache code in git

When using Git to manage code, we often encounter situations where we need to roll back the code. In Git, there are three different areas, including the work area, the staging area and the code warehouse, so the methods of rollback are also different. This article will focus on how to roll back the code in the Git cache.

1. Introduction to Git cache area

The cache area in Git (also called the temporary storage area) refers to the area where we use the Git add command to add files to Git. In other words, when we execute the Git add command, the file modifications will be temporarily stored in the Git cache, waiting to be submitted to the code repository. Therefore, if you need to roll back the code in the cache area, you need to use the Git reset command.

2. Roll back the code in the Git cache

1. Use the Git reset command to roll back a single file

If you only need to roll back a certain file To modify the cache area, you can use the following command:

git reset <file></file>

where is the name of the file to be rolled back. After executing the above command, Git will undo all modifications of in the cache area and roll back the file to the state of the previous submitted version.

2. Use the Git reset command to roll back multiple files

If you need to roll back the modifications of multiple files in the cache area, you can use the following command:

git reset <file1> <file2> <file3></file3></file2></file1>

Among them, , and are the names of the files to be rolled back. After executing the above command, Git will undo all modifications to the specified files in the cache area and roll back these files to the state of the last submitted version.

3. Use the Git reset command to roll back all files

If you need to roll back all the files in the cache, you can use the following command:

git reset

Execute After the above command, Git will undo all modifications to all files in the cache and roll them back to the state of the last submitted version.

3. Summary

In Git, the cache area is a very important concept, and it is one of the keys to achieving code version control. Through the above introduction, we can clearly know how to roll back the code in the Git cache and return it to its previous state. When using Git on a daily basis, if you encounter code problems, you may wish to use the Git reset command to roll back the code in the cache to ensure the stability and accuracy of the entire code base.
