git之简单入门及操作～

看了bili的教程，https://www.bilibili.com/video/av23853294?from=search&seid=3300012850779227291

特此整理下。

1、首先安装git，然后最好国内镜像，否则下载很慢
2、其次，可以注册github的账号，后面会用到。
3、把git和github链接起来，就是建立连接，右键打开git bash here，输入ssh-keygen，会中C:\Users\Administrator\.ssh文件夹下生成两个文件，打开id_rsa.pub，把里面的信息全部拷贝的github之SSH and GPG keys中。这样就把git和github建立了链接。
4、新建一个文件，打开文件，右键git bash here，
可以看到如下信息：

a、git init命令

Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git
$ git init
Initialized empty Git repository in C:/Users/Administrator/Desktop/maple_stm_git/.git/

b、git remote add origin命令，把github的链接和本地文件建立连接
Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git (master)
$ git remote add origin https://github.com/liming2013/maple.git

c、git pull origin master命令，下载代码到本地文件夹中
Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git (master)
$ git pull origin master

remote: Total  (delta ), reused  (delta ), pack-reused
Receiving objects: % (/), 7.86 MiB | 74.00 KiB/s, done.
Resolving deltas: % (/), done.
From https://github.com/liming2013/maple
* branch master -> FETCH_HEAD
* [new branch] master -> origin/master
d、git add命令，在文件夹中添加几个文件，然后add到stage区域，中间需要空格。
Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git (master)
$ git add a.c ble_nrf_add.txt

Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git (master)
$ git commit -m "add"
[master d381232] add
 files changed,  insertions(+)
create mode  a.c
create mode  ble_nrf_add.txt

e、git push origin master命令，上传文件之github

Administrator@PC-20150323YSLL MINGW64 ~/Desktop/maple_stm_git (master)
$ git push origin master

f、“git add .”命令，可以添加文件夹中全部的文件
