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`.
Read MoreGit Remote Repository Configuration: Adding, Modifying, and Deleting Remote Repository URLs
This article introduces methods for managing Git remote repository addresses, suitable for beginners. A remote repository is a cloud-hosted Git repository (e.g., GitHub), where the local repository is associated with the remote via an address, supporting operations like push (pushing local code to the remote) and pull (pulling remote code to the local). ### Core Operation Steps: 1. **Check Association**: Execute `git remote -v`. If there is no output, no association exists. 2. **Add Address**: Use `git remote add [alias] [address]`. The default alias is `origin`, and the address can be copied from the remote platform (supports HTTPS or SSH formats). 3. **Modify Address**: When the address changes, run `git remote set-url [alias] [new address]`. 4. **Delete Address**: Use `git remote remove [alias]` or `rm`. After deletion, the association must be re-established by re-adding the address. ### Notes: - The address format must be correct (HTTPS includes `https://`, SSH starts with `git@`); - Aliases must be unique to avoid duplicates; - After modifying an HTTPS address, re-authentication of account credentials may be required; - After deletion, the association must be re-added to restore the connection. (Note: The original text ends abruptly with "Through `git remote -", so the translation includes the visible content only.)
Read MoreGit Clone Operation: Copying a Project from a Remote Repository to the Local Machine
This article introduces the Git clone operation, which is used to completely copy a remote repository project to the local machine. The core steps are as follows: **Prereparations**: First, install Git, configure your identity (`git config --global user.name/email`), and obtain the remote repository address (in HTTPS or SSH format). **Performing the Clone**: Use the command `git clone [remote URL] [local folder name]`. By default, a folder with the same name as the repository is created, and you can also customize the local name (e.g., `git clone [URL] my-project`). **After Clone**: The local machine will contain all project files and branch structures. The remote repository is by default marked as "origin", which can be verified using `git remote -v`. **Common Issues**: For permission/address errors, check the address or permissions. If the speed is slow, SSH is recommended. To clone only a specific branch, use the `-b` parameter (e.g., `-b dev`). To avoid entering passwords: use `credential.helper` for HTTPS, or configure SSH keys. Cloning is the first step in Git usage. Once mastered, you can develop locally and push/pull updates.

Git is a version control system that records file modifications and supports multi-person collaboration. GitHub is a web-based repository platform built on Git, used for code storage and collaboration. **Preparation**: Install Git (download from the official Windows website, use Homebrew or the official website for Mac, verify with `git --version`); register a GitHub account. **Create a Repository**: Log in to GitHub, click "+" → "New repository", fill in the name and description, select Public, check "Add README", and after creation, copy the repository URL (e.g., `https://github.com/username/project.git`). **Local Association**: Navigate to the local project folder, execute `git init` to initialize the repository; `git remote add origin [repository URL]` to associate with the remote. If there is a README, first `git pull origin main` to pull (to avoid conflicts); `git add .` to stage, `git commit -m "notes"` to commit, and `git push origin main` to push to the remote. **Core Commands**: `git init` (initialize), `git add .` (stage), `git commit -m "..."` (commit), `git push origin main` (push). **Common Issues**: Conflicts can be resolved by pulling; if the remote association is incorrect, first use
Read MoreGit Version Control Basics: What is a Version Control System?
Version control solves the problem of "breaking changes and being unable to revert" and multi - person collaboration. A Version Control System (VCS) is an "intelligent filing cabinet" that can record modifications, support rollbacks, and enable collaboration. VCS is divided into three categories: local (only for a single device), centralized (relying on a central server, such as SVN), and distributed (with a complete local copy, such as Git, which can be used offline and has flexible branches). Git is a mainstream distributed VCS developed by Linus Torvalds. Its core advantages include: fast speed, strong branch management (supporting parallel development), and tracking file differences (saving space). Its core concepts include: repository (local/remote), commit (snapshot recording modifications), and branch (parallel development path). Git can handle scenarios such as multi - person collaboration, historical rollbacks, and parallel development. It is an essential skill for programmers, making development more organized and efficient.
Read More详解Git暂存区：为何需先执行add再进行commit？
This article introduces Git's staging area and core operation logic. Git consists of three areas: the working directory (where files are manipulated), the staging area (a transfer station), and the local repository (historical versions). The staging area is a critical filter before commits. The core logic is "add first, then commit": the staging area allows step-by-step commits (e.g., dividing a novel into chapters), preventing accidental commits of incomplete work. `git add` adds modifications from the working directory to the staging area, while `git commit` submits the staged content to the local repository to form a version. Key points: Committing directly without adding will prompt "nothing to commit". `git reset HEAD <filename>` can undo changes in the staging area. The staging area enables flexible commits, ensures version clarity, and acts as the "final checkpoint" before Git commits. In summary, the staging area, through filtering and transfer, enables staged commits, modification checks, and flexible adjustments, being a core design to avoid accidental commits and maintain historical clarity.
