1、当生产要上线时需要把开发分支(dev为例)合并master

	git checkout dev
	git pull
	git checkout master
	git merge dev
	git push -u origin master

2、当产品定义好之后需要从master 拉到dev

	git checkout master 
	git pull 
	git checkout dev
	git merge master 

3、当git 冲突时候

	git  stash 
    git stash pop

4、新建分支和删除分支

 git checkout -b dev 新建（然后在提交）
 git branch -d dev 删除本地分支
 git push origin --delete dev 删除远程分支

5、打tag

	git tag  查看本地的所有Tag
	git tag -a v1.0 -m "对Tag的描述信息" 创建tag命令
	git push origin --tags 提交tag命令(远程)
	git tag -d v1.0  删除tag命令
 	git push origin --delete tag v1.0 删除远程tag

6、多个钩子问题

hint: You've added another git repository inside your current repository.
hint: Clones of the outer repository will not contain the contents of
hint: the embedded repository and will not know how to obtain it.
hint: If you meant to add a submodule, use:
hint: 
hint: 	git submodule add <url> proposal
hint: 
hint: If you added this path by mistake, you can remove it from the
hint: index with:
hint: 
hint: 	git rm --cached proposal
hint: 
hint: See "git help submodule" for more information.

解决方案：

rm -rf ./proposal/.git
