How to delete a folder in git? Notes on sharing

In the process of using Git for project management and version control, we often encounter situations where we need to delete folders. However, due to the characteristics of Git, it is not easy to delete the folder directly. This article will give you a detailed introduction to how to delete a folder on Git, as well as precautions and solutions to common problems.

1. Why is it troublesome to delete folders in Git?

Git is a distributed version control system. It is different from other version control systems in that it uses snapshots to store file changes. In this process, the so-called version control actually compares each snapshot to find out the changes brought about by each submission. In this process, Git assumes many functions, one of which is folder management.

However, this also makes deleting folders on Git more troublesome. Because Git not only deletes the files in the folder, but also deletes the folder itself, and the folder itself may also contain other subfolders and files, and these subfolders and files also need to be deleted. It should be noted here that if you directly use a regular deletion command (such as rm -rf) to delete a folder, Git will not immediately record the deletion operation in the file change list recorded by Git. Instead, Git will record this operation as a modification operation, and then delete the corresponding folder during the next commit. The reason for this is that Git cannot know whether the files in the folder really want to be deleted, because it is possible that this operation is only temporary and needs to be used again later.

2. How to delete a folder on Git?

To delete a folder on Git, it is recommended to use the following two methods:

Method One: Use the git rm command

Delete files and files by using the git rm command folder, this command will record the operation in Git's file change list, and the deletion operation can be submitted normally. Before deleting a folder, you need to make sure that your current working directory is the parent directory of the folder. Just enter the following command in the terminal:

git rm -r <文件夹名>

where -r means to delete recursively. If there are other files or subfolders in the folder, they will also be deleted. After performing this operation, you also need to record the operation as a commit through the git commit command. For example:

git commit -m "删除文件夹 xxx"

Method 2: Manual deletion

Manual deletion may not be a safe thing, because during this process, unrecoverable errors or file omissions may occur. . Therefore, we recommend using the git rm command to delete the folder. If you still want to try manually deleting the folder, make sure you have backed up important files or use the delete function in your version control system.

3. Precautions and solutions to common problems

When deleting a folder, please pay attention to the following points:

1. Please ensure that you are performing the deletion operation Back up important files beforehand to avoid accidentally deleting important data.

2. If there is a misreading problem when deleting a folder, you can use the git checkout command to restore the folder, as shown below:

git checkout -- <文件夹名>

3. If your deletion operation is not successfully recorded In commit, it might be because you didn't commit after deletion. You can use the following command to view the file change record:

git status

4. If the git rm command cannot delete the file (the file has been locked by another program), you can try using the following command (this command will forcefully delete the file) Files):

git rm -f <文件名>

In short, the process of deleting folders and files should be handled with caution to avoid data loss and incorrect operations. At the same time, when using Git for team collaboration, you should also comply with the team's collaboration specifications and code management process.
