git 新建分支并关联远程分支

## 1、在当前分支下（一般是master分支），创建feature的本地分支分
$ git checkout -b feature
Switched to a new branch 'feature'

## 2、将feature分支推送到远程
$ git push origin feature

   Total 0 (delta 0), reused 0 (delta 0)
   To code.aliyun.com:1273398724/test.git
   * [new branch] feature -> feature

## 3、将本地分支feature关联到远程分支dev上  
$ git branch --set-upstream-to=origin/feature
Branch 'feature' set up to track remote branch 'feature' from 'origin'.

## 4、查看本地分支和远程分支的映射关系
$ git branch -vv

   dev b87904a [origin/dev] test
   * feature b87904a [origin/feature] test
   master b87904a [origin/master] test

## 5、查看远程分支
$ git branch -r

   origin/dev
   origin/feature
   origin/master

## 6、查看本地各个分支目前最新的提交
$ git branch -v

   dev b87904a test
   * feature b87904a test
   master b87904a test

## 7、查看远程各个分支目前最新的提交
$ git branch -r -v

   origin/dev b87904a test
   origin/feature b87904a test
   origin/master b87904a test
