Notes: Git version management system

Git is a version management system (VCS). It can save the status of the document as an update record at any point in time, or it can reply to the update record at any point in time

Version management is a way to record file changes so that you can check the content of a specific version of the file in the future

Download git first (https://npm.taobao.org/mirrors/git-for-windows/)
The next step all the way, after the installation is complete, it will appear in the right-click menu of the mouse, the most commonly used Git bash here

切换分支

git branch 分支名称


如果在此分支上的内容没有处理好，那么此分支上的内容会被带到转换的分支上
切换分支之前要保证每个分支互不干扰

合并分支

git merge 来源分支

删除分支

git branch -d 分支名称

先切换到其他分支上
分支被合并后才允许删除

-D 强制删除

git repository: used to store submission records
Temporary storage area: temporarily store modified files
Working directory: project directory managed by git
Every time the developer submits the project status to the git warehouse, he must first submit the modified files from the working directory to the temporary storage area, and then submit the files in the temporary storage area to the git warehouse.

git configuration

Before using git, you need to tell the git information, which is needed when the item git warehouse is submitted

git branch

For ease of understanding, you can think of a branch as a copy of the code in the current working directory
Using branches allows us to separate from the main line of development, so as not to affect the main line of development

Master branch

The first time an update record is submitted to the git repository is a branch automatically generated
To maintain the stability of the code in the main branch

Development branch (develop)

Feature

As a branch to develop specific functions, create based on the development branch

Save changes temporarily

All changes on the branch can be temporarily extracted and stored, so that developers can get a clean working copy, and temporarily move to other work
Find out which branch you are on before executing
