git 分支管理总结

1.创建分支

git co -b 20140501-yunpeng-dev

2.切换分支

git co 20140501-yunpeng-dev

3. 切换回master

git co master

4. merge

git merge 20140501-yunpeng-dev

这里注意一点是git会自作聪明的自动帮你ci，而svn 的merge只在本地。如果还想在本地再check一下文件改动，可以使用git reset

5. reset

git reset --mixed  origin/master

应该等效git reset origin/master，没试过

本地创建分支

git checkout -b 20140109_rpcspan_jiangyunpeng master

本地分支push到remote

yunpeng@yunpeng-duitang:/duitang/dist/app/branches/eagleeye$ git push origin 20140109_rpcspan_jiangyunpeng

从remote获取到分支

git clone -b 20140109_rpcspan_jiangyunpeng  [email protected]:middleware/xxx.git

把分支merge到master

#切换到master
yunpeng@yunpeng-duitang:~/test/temp/eagleeye$ git checkout master
Branch master set up to track remote branch master from origin.
Switched to a new branch 'master'

#查看分支情况
yunpeng@yunpeng-duitang:~/test/temp/eagleeye$ git branch -r
  origin/20140109_rpcspan_jiangyunpeng
  origin/HEAD -> origin/master
  origin/master

# 对开发分支进行合并，这条命令git会合并完成之后自动commit
git merge --no-ff 20140109_rpcspan_jiangyunpeng 

#如果不想自动ci ,参考：http://stackoverflow.com/questions/8640887/git-merge-without-auto-commit
yunpeng@yunpeng-duitang:~/test/temp/eagleeye$ git merge --no-commit --no-ff origin/20140109_rpcspan_jiangyunpeng

查看代码变更

#使用git diff没有效果，参考：http://stackoverflow.com/questions/4944376/how-to-check-real-git-diff-before-merging-from-remote-branch

yunpeng@yunpeng-duitang:/duitang/dist/app/branches/eagleeye$ git diff origin/master

如果提交了代码想revert掉，怎么办？

yunpeng@yunpeng-duitang:~/test/temp/eagleeye$ git st
# On branch master
# Your branch is ahead of 'origin/master' by 4 commits.

yunpeng@yunpeng-duitang:~/test/temp/eagleeye$ git reset --hard origin/master
HEAD is now at d2c6808 Add: 增加对一个目录下有错误的 seq 文件的修复功能。增加 ListFiles 查看各个目录、文件的数据备份数和实际占用空间
