A brief analysis of how to build a Git environment locally

With the development of software development, code management has become crucial. Git is one of the most popular version control systems today and is widely used in open source and private projects. In this article, we will introduce how to set up a local Git environment to better manage and collaborate on your code.

Preparation

Before starting, you need to install Git first. If you have not installed Git, you can download the Git installation package suitable for your operating system from the Git official website (https://git-scm.com/downloads). After the installation is complete, enter the following command to check whether the installation was successful:

git --version

This should output the installed Git version, for example:

git version 2.22.0

Create repository

In Git, A repository is where you store your code. You can use the following command to create a new repository locally:

mkdir myproject
cd myproject
git init

After executing these commands, Git will create a new repository in the myproject directory. Now you can add your code to the repository and manage it.

Adding and Submitting Code

When you add code to a new repository, you need to add them to Git tracking. You can use the following command to add files to the repository:

git add file1 file2 file3

If you want to add all new or modified files, you can use the following command:

git add .

After adding all the files, You need to commit your changes to the repository. You can commit your changes using the following command:

git commit -m "initial commit"

This will commit the changes to the repository and leave a message in the commit record.

Branch Management

Git is very suitable for branch management of code. A branch is an independent code development path that allows you to experiment without affecting the main code. You can create a new branch named new_branch using the following command:

git branch new_branch

To switch to the new branch, enter the following command:

git checkout new_branch

Now you can modify the code on that branch while Will not affect the main branch. To merge the changes in the new branch into the master branch, enter the following command:

git checkout master
git merge new_branch

This will merge the changes in new_branch and apply them to the master branch.

Remote repository

You can synchronize your local repository with a remote repository to share code among multiple team members. To push a local repository to a remote repository, enter the following command:

git remote add origin git@github.com:username/myproject.git
git push -u origin master

The first command will add a remote repository named origin. The second command will push your local branch onto the remote branch and track downstream changes.

To pull changes from the remote repository, enter the following command:

git pull origin master

This will merge the remote changes into your local branch.

Summary

Git is a very powerful version control system that can help you better manage and collaborate on your code. In this article, we introduce how to set up a local Git environment and perform basic code management and collaboration. I hope this content can help you better master the use of Git and improve code management and development efficiency.
