Git & github 最常用操作笔记

基本配置

 git config --global user.name "foobar"		
 git config --global user.email "foo@bar.com"	
 git config --global core.editor vim		
 git config --global color.ui true
 git config --global merge.tool vimdiff

查看已有配置信息可用 git config --list

开始使用git

到项目所在的目录，执行 git init

添加与提交文件

 git add *.c
 git commit -m "first commit"

生成SSH密钥过程（用于连接github）
1. 查看是否已经有了ssh密钥：
```
 cd ~/.ssh
```
  如果没有密钥则不会有此文件夹，有则备份删除
2. 生成密钥：
```
 ssh-keygen -t rsa -C "foo@bar.com"
```
  最后得到了两个文件：id_rsa和id_rsa.pub
3. 登录github，添加 id_rsa.pub 里面的公钥。
4. 测试：ssh git@github.com
  
  The authenticity of host ‘github.com (207.97.227.239)’ can’t be established.
  
  RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
  
  Are you sure you want to continue connecting (yes/no)? yes
  
  Warning: Permanently added ‘github.com,207.97.227.239′ (RSA) to the list of known hosts.
  
  ERROR: Hi tekkub! You’ve successfully authenticated, but GitHub does not provide shell access
  
  Connection to github.com closed.

本地已有代码，推送到一个远程仓库上

 git remote add origin https://github.com/foo/bar.git
 git push -u origin master

克隆一个远程仓库

 git clone git@github.com:billyanyteen/github-services.git

将本地repo与远程的origin的repo合并

推送本地更新到远程仓库
```
 git push -u origin master
```
远程仓库更新到本地
```
 git pull origin master
```
