# 1. git使用手册

## 1.1. 概述

  git是分布式版本控制系统，在多人开发中，git可以很好的管理代码的版本。

## 1.2. 源码托管服务器

  github和gitlab还有gitee（国产）都是开源的代码托管服务器，可以用来管理源码。

## 1.3. git安装

## 1.4. git分支管理

### 1.4.1. git创建本地分支

* 基于远端分支创建一个本地分支，同时新建一个对应的远端分支：

  当主干发生较大变化，例如：原厂更新sdk时，需要新建分支，划分界限。

```
$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/app_test
  remotes/origin/master
$ git checkout -b master-sdk-202405 origin/master
M       ipc-sdk
Branch 'master-sdk-202405' set up to track remote branch 'master' from 'origin'.
Switched to a new branch 'master-sdk-202405'
$ git branch -a
  master
* master-sdk-202405
  remotes/origin/HEAD -> origin/master
  remotes/origin/app_test
  remotes/origin/master
$ git push origin master-sdk-202405:sdk-202405

## 1.5. 存疑

* 不同的分支之间如何同步某个文件？
