==== 创建和合并分支 ====



<code>



#git branch 显示当前分支是master



#git branch new-feature  创建分支



# git checkout new-feature 切换到新分支



# vi page_cache.inc.php



# git add page_cache.inc.php



Commit 到本地GIT



# git commit -a -m "added initial version of page cache"



合并到远程服务器



# git push origin new-feature







如果new-feature分支成熟了，�
��得有必要合并进master



#git checkout master



#git merge new-feature



#git branch



#git push 



则master中也合并了new-feature 的代码



</code>



==== 通过tag创建Branch,并提交 ====

  git tag v1.0.0 2c1b73235f77e6204e0b584cfae692486ccf3e92

  git branch leili-v1.0.0 v1.0.0

  git checkout leili-v1.0.0

  git push origin leili-v1.0.0





==== 删除服务器branch ====
  git push origin  :server-branch-name

==== git checkout remote branch ====
Check the remote branch list
  git branch -rv
Then create a local branch from the remote branch
  git checkout -b test origin/test
  
Commit to a remote branch:
  git push origin proguard
  
Reference:http://stackoverflow.com/questions/1783405/git-checkout-remote-branch
  
==== git add local to the remote  ====

  * http://stackoverflow.com/questions/2364147/how-to-get-just-one-file-from-another-branch

  git checkout branch_name -- path/to/file
  
==== git revert ====

github support revert the pull request, so after you have revert the pull request, and still want to merge the feature branch, then you need to find the revert commit id, and revert it again

  git revert ce8731f5cbc55ab50723ee2a8ec615b462b3b0e6 -m 1

So the full log will be like
<code>
