Git Getting Started Tutorial

1. What is Git?

Git is an open source distributed version control system. Can effectively and quickly handle project version management from very small to very large.
Generation background:
Git is an open source version control software developed by Linus Torvalds to help manage Linux kernel development.

2, Features and Advantages

Distributed:
Divide and conquer, summarize and integrate, more efficient and convenient.
The biggest difference between distributed and centralized is that developers can submit to local, and each developer can clone (git clone //command statement, detailed explanation below). Copy a complete Git repository on your local machine.
Can be rolled back:
Git can completely record the iteration and corresponding status of the development version. In the event of an unexpected situation, you can roll back to the previous stable version.

Another major advantage of git is the support of Github, which is very beneficial to team collaboration.

3, Function

From the perspective of a general developer, git has the following functions:
1. Clone the complete Git repository (including code and version information) from the server to On a single machine.
2. Create branches and modify the code on your own machine according to different development purposes.
3. Submit the code on the branch you created on a single machine.
4. Merge branches on a single machine.
5. Fetch the latest version of the code on the server, and then merge it with your main branch.
6. Generate a patch and send the patch to the main developer.
7. Look at the feedback from the main developer. If the main developer finds that there is a conflict between two general developers (a conflict that can be resolved cooperatively between them), they will be asked to resolve the conflict first, and then one of them will Submitted by people. If the lead developer can resolve it himself, or there are no conflicts, pass.
8. Generally, developers can use the pull command to resolve conflicts. After resolving conflicts, they can submit patches to the main developer.

From the perspective of the main developer (assuming that the main developer does not need to develop code), git has the following functions:
1. Check emails or check the submission status of general developers through other methods.
(You can see how much code you have submitted at work, and whether you are at work or playing games. Well, let’s have a cup of tea.)
2. Apply patches and resolve conflicts (you can resolve them yourself, or you can ask the developer Resubmit it after solving the problem. If it is an open source project, you also need to decide which patches are useful and which ones are not).
3. Submit the results to the public server and then notify all developers.

Maybe you are not clear about pull fetch and other git commands. Here, I will give you a picture~~

4, usage

Create a local warehouse
Register a Github account and create a warehouse.
Set SSH key
If it is an existing project (usually this is the case, the company often already has a complete project) fork to your own account, clone to the local warehouse, and perform related development and maintenance.
For a new project, you only need to develop it locally, then upload it to the warehouse on Github, submit it, and jointly debug it.
