This article will help you quickly understand git

With the rapid development of software development, version control has gradually become an important topic. Git is one of the most popular version control systems currently. It provides programmers with an effective way to track the change history of code, collaborate on development, and manage different versions. Although Git can be slightly complex for beginners, But as long as you follow the steps below, you can quickly understand Git.

1. Install Git, and set the name and email

Git can be downloaded for free from the official website https://git-scm.com/downloads. After installation, you need to run it in the terminal Set name and email. For example:

git config --global user.name "your name"
git config --global user.email "your email"

2. Creating a warehouse and preliminary operations

You need to create a warehouse before using Git. You can use the following command to create and enter the warehouse directory:

mkdir my_project
cd my_project
git init

Git's local warehouse contains three areas: work area, staging area and version library. Our modifications to the code first occur in the workspace, and then we need to add the modifications to the staging area and finally submit them to the repository.

The following are some commonly used Git operation commands:

• View the current status: git status
• Add files to the temporary storage area: git add [file name]
• Submit the staging area file to the repository: git commit -m "message"
• View the version history: git log
• Undo the last submission: git revert HEAD
• Go back to a certain version: git reset [commit id]

3. Branch and merge

One of the most powerful features of Git It's a branch. Use branches to quickly work on different parts of the project, develop new features or resolve bugs without directly affecting the main version. The following are some common commands for Git branching and merging:

• Create a new branch: git branch [branch name]
• Switch to a branch: git checkout [branch name]
• View all branches: git branch
• Merge branches: git merge [branch name]
• Delete branches: git branch -d [branch name]

4. Usage of Github

Github is a very popular Git remote hosting service. You can share code and interact with the open source community through Github. Here are some commonly used commands on Github:

• Pull code from Github: git clone [repository url]
• Will Push local code to Github: git push
• Get the latest updates from Github: git pull
• Create a new branch or PR (Pull Request) on Github
• In Github Conduct code comments and diagnosis on the website, and conduct collaborative development

Blindly using Git will lead to wrong delays in completing your work, so it is very necessary to have an in-depth understanding of Git and practice it in the project. Mastering the Git version control system will help achieve more efficient development and fewer code conflicts, improving code quality and maintainability.
