Let's start the class. How to use the git tool in MaTang?

KaikebaMatang is an emerging online programming education institution. Its business scope covers course research and development, teaching services, talent training, consulting services, etc. The courses it offers cover many fields and cover students and entrepreneurs at different levels. Among them, the main languages ​​and frameworks involved in MaTang courses include Python, Java, machine learning, data analysis, Web front-end, mobile development, etc.

In programming teaching, code management is an essential link. KaibaMatang uses Git as the main code management tool to allow students to better practice team collaboration, project management and other aspects of their abilities.

This article will introduce the steps to use the Git tool of Kaikeba Matang, including the basic concepts of Git, common commands, version rollback, etc. I hope it can help readers better understand how to use Git and improve their programming skills.

1. The basic concept of Git

Git is a distributed version control system. It mainly solves the problem of code confusion and irreversibility caused by team development and version iteration during the code management process. Return issues. Git provides the following basic concepts:

1. Version Control

Git can help us store and track modified code versions, so we can easily roll back the code and avoid problem appear. In addition, Git can also record who modified the code at what time, making project management easier.

2. Branch Management

Git provides branch management functions that allow us to create different branches to handle different tasks. These branches can be developed in parallel without affecting the main branch, making it easier for team collaboration.

3. Team collaboration

Git's distributed version control system allows team members to access code from anywhere, and changes between each member can be merged into the code base middle.

2. Common Git commands

1. git clone

This command can clone a Git library to the local and is used to copy a code warehouse from a remote location. For example, we can use the following command to copy a GitHub repository:

git clone https://github.com/user/hello-world.git

2. git add

This command can add files to the Git repository and prepare it for submission for one version. For example, we can use the following command to add all files in the directory to the Git library:

git add *

3. git commit

This command can add all files in the Git library Good files are submitted as a version. When submitting, you need to write down the comments for this version and record the changes. For example, we can use the following command to commit a version:

git commit -m "这是一个示例提交"

4. git push

This command can push a version in the local Git repository to the remote Git repository. For example, we can use the following command to push the local master branch to the Github repository:

git push origin master

5. git pull

This command can pull the latest from the remote Git repository code to the local Git repository. For example, we can use the following command to pull code from a Github repository:

git pull origin master

6. git branch

This command is used to create, list, or delete Git branches. For example, we can use the following command to list branches in the local Git repository:

git branch

7. git checkout

This command is used to switch Git branches. For example, we can use the following command to switch to another branch:

git checkout another-branch

3. Version rollback

Version rollback is a basic function of Git, which can easily retrieve historical versions. Avoid the consequences caused by version problems. The following are some commands for version rollback.

1. git log

This command can view the historical commit records of the Git library. For example, we can use the following command to view the recent commit history:

git log -1

2. git reset

This command can roll back the version of the Git library to the specified version. For example, we can use the following command to roll back the Git library to the previous version:

git reset --hard HEAD^

3. git revert

This command can roll back the version of the Git library to the specified version and generate a new commit record. For example, we can use the following command to roll back the Git library to the previous version and generate a new commit record:

git revert HEAD

Summary

This article introduces the use of the Kaikeba Matang Git tool Methods, including basic concepts of Git, common commands, version rollback, etc. Through studying this article, I believe that readers have understood the basic concepts and operating procedures of Git, and can better apply Git tools for team collaboration and project management. At the same time, readers can also delve into more advanced uses of Git tools based on actual situations and improve their programming level.
