This article addresses a common issue in Git version control where developers accidentally work on the wrong branch (e.g., master) and need to migrate uncommitted changes to the correct topic branch (e.g., branch123) without polluting the main branch history. Focusing on the best-practice solution, it details the workflow using git stash, git checkout, and git stash apply commands, with code examples and explanations of how this approach avoids committing to master. The analysis covers underlying Git mechanisms, potential risks, and alternative methods, providing a reliable strategy for branch management.

This paper provides an in-depth analysis of best practices for handling uncommitted changes in Git version control systems. When developers edit files on the main branch and later decide to move these changes to an experimental branch, complex file copying operations are unnecessary. Through detailed examination of the git checkout -b command mechanism, the paper explains how Git intelligently preserves modifications in the working directory while creating new branches. The discussion extends to branch push configuration, ensuring local branches synchronize correctly with corresponding remote repository branches, covering .git/config file settings and various usages of git push commands. With code examples and step-by-step explanations, this guide offers a complete and safe workflow solution for developers.
