This article delves into best practices for handling conflicts between remote and local branches in Git collaborative development. By analyzing the default behavior of git pull and its limitations, it highlights the advantages and implementation of the git pull --rebase strategy. The paper explains how rebasing avoids unnecessary merge commits, maintains linear commit history, and discusses the reversal of theirs and ours identifiers during conflict resolution. Additionally, for team collaboration scenarios, it presents advanced techniques such as using feature branches, regular rebasing, and safe force-pushing to help developers establish more efficient version control workflows.

This article provides an in-depth exploration of techniques for effectively squashing multiple commits into one when Git commit history contains merge commits. Using practical development scenarios as examples, it analyzes the core principles and operational steps of using interactive rebase (git rebase -i) to handle commit histories with merge commits.
