Git Quick Start: Master Basic Operations in 30 Minutes

Git is a distributed version control system (VCS) used to record file modification history, enabling team collaboration and personal history回溯 (retrospection). Its core advantages include version rollback (to prevent accidental modifications), multi - person collaboration (code merging), and local security management (operations first local, then cloud - based). Basic concepts are metaphorized by "areas": Working Directory (drafts), Staging Area (items to be committed), Local Repository (file cabinet), and Remote Repository (cloud - based shared library). Basic operations are divided into five steps: 1. Initialize the repository (`git init`); 2. Configure user information (`config`); 3. Track and commit changes (`status` to check status, `add` to stage, `commit` to save); 4. Version management (`log` to view history, `reset` to roll back); 5. Branch operations (`checkout - b` to create a branch, `merge` to combine branches); 6. Remote repository operations (`clone`, `push`, `pull`). The core principles are "timely commits, branch management, and version rollback", with a key command chain: `init→add→commit→log/reset→branch→push/pull`. Basic operations can be mastered in 30 minutes. For common issues like modifying commit messages, use `--amend`.
