This paper delves into the technical details of managing ignored files in the Git version control system after they have been committed to the repository. It begins by explaining the fundamental workings of the .gitignore file, highlighting that it only affects untracked files and cannot automatically remove committed ones. The paper then details the specific steps for removing committed files using the git rm --cached command, including command syntax, parameter meanings, and practical examples. Additionally, it analyzes supplementary methods, such as clearing the entire cache and re-adding files, to offer a comprehensive solution. Through code examples and step-by-step explanations, this paper aims to help developers understand core Git concepts, avoid common pitfalls, and master practical techniques for efficiently managing ignored files in real-world projects.

With specific historical diagram illustrations, the article discusses applicable scenarios and potential risks of different methods, helping developers understand the underlying principles of merge reversion and master correct re-merge workflows.

This article addresses the issue where git pull may fail to fully synchronize code from a remote repository during server deployments. By examining a common scenario—local uncommitted changes preventing complete pulls—it delves into the merge mechanism of git pull and its limitations.
