Let's talk about how to delete and add files on git

When using git to manage projects, we need to continuously add files and folders to the repository for version control and collaborative development. However, sometimes we may add wrong files or unnecessary files, and at this time we need to delete them from the repository. This article will introduce in detail how to delete added files in git.

1. Check the git status

Before deleting the file, we need to check the git status to determine whether the file to be deleted has been submitted to the repository. You can use the following command to view the git status:

$ git status

If the git status contains files that need to be deleted, you can continue with subsequent deletion operations.

2. Delete a single file

If you need to delete a single file, you can use the following command:

$ git rm [file]

where [file] represents the name of the file that needs to be deleted. After executing this command, git will delete the file from the repository and add the deletion operation to the staging area. At this time, you need to use the following command to submit the modification to the repository:

$ git commit -m "delete file"

Note that if you need to undo the deletion operation, you can use the following command:

$ git restore [file]

where [file] represents the file that needs to be restored name.

3. Delete folder

If you need to delete the entire folder, you can use the following command:

$ git rm -r [folder]

where [folder] represents the folder that needs to be deleted name. After executing this command, git will delete the folder and all the files it contains from the repository, and add the deletion operation to the staging area. You also need to use the following command to submit the modification to the repository:

$ git commit -m "delete folder"

If you need to undo the deletion of the folder, you can use the following command:

$ git restore [folder]

where [folder] represents the name of the folder that needs to be restored. .

4. Recover deleted files

If you need to recover deleted files, you can use the following command:

$ git checkout [commitID] -- [file]

where [commitID] indicates the need to restore The commit ID, [file] indicates the file that needs to be restored. After executing this command, git will restore the file to the specified commit ID version.

5. Deletion error handling

In the process of using git to delete files, in some cases, files or folders that should not be deleted may be deleted, causing unnecessary Loss. At this time, we can handle it through the following methods:

• Re-add the accidentally deleted files or folders
• Restore the deleted commit ID version

If a submitted file is accidentally deleted, you need to directly restore the submitted commit ID version. If the accidentally deleted file is not submitted to the repository, it can be remedied by re-adding it.
