Why can't git delete it?

Git is one of the most popular version control systems currently, but many beginners will encounter a problem when using Git, that is, they cannot delete files or folders. This article will provide an in-depth analysis of this problem and provide solutions.

First of all, we need to understand the three areas in Git: workspace, staging area and repository. In Git, we can add files or folders in the workspace to the staging area through the add command, and submit the contents of the staging area to the repository through the commit command. If we want to delete files or folders, we need to delete them in the workspace, perform a series of operations, and finally submit the deletion to the repository.

However, in some cases, we may find that the deletion operation cannot be submitted to the repository, for example:

1. The files or folders in the workspace have been deleted, But when executing the git status command, it still shows that it is not deleted.
2. After executing the git rm command, the prompt "fatal: pathspec 'xxx' did not match any files" means that the file or folder to be deleted cannot be found.

These problems usually occur due to the following reasons:

1. Git manages the file content, not the file name. If the deleted file does not have any modifications, Git will not regard it as a modified file, so the deletion will not be included in the commit.
2. The file or folder is not tracked by Git. If you use the git add command to add a file or folder to Git tracking but remove it before Git commits it, Git will treat it as an untracked file or folder. In this case, Git logs nothing, so the delete operation cannot be submitted.
3. Git caches something. In some cases, Git may cache some data before deletion, including indexes, hash values, etc. This will cause Git to be unable to find the file to be deleted, causing the problem of being unable to delete it.

In order to solve the above problem, it is recommended to take the following measures:

1. Make sure that the deletion operation has been performed. If you have deleted files or folders in your workspace, run the git status command to see the status. If the file still appears as undeleted, you may need to execute the git add command to add the deletion.
2. Check whether the file or folder is tracked by Git. Run the git status command to check whether a file or folder exists in the Git repository. If it is not tracked, you can use the git add command to add it to the Git tracking before performing the deletion operation.
3. Clear Git cache. You can run the git rm --cached command to clear the indexes and hashes in the Git cache. Then try the delete operation again.

To summarize, when we encounter a situation where we cannot delete a file or folder when using Git, we need to first check whether the deletion operation has been performed and determine whether the file or folder is tracked by Git. If the above method still does not solve the problem, you may need to clear the Git cache or reset the Git repository. Finally, it is recommended to read the documentation carefully and master basic Git operations when using Git to avoid similar problems.
