git diff
使用git diff --staged比较工作区与暂存区的不同。
使用git diff --cached比较暂存区与本地库的不同。
分支管理分支可以并行推进项目的开发，开发的某一个功能如果失败不会影响项目整体。
查看分支（git branch -v）
niko@niko-notebook:~/StydyGit$ git branch -v * master bcf8ce2 first reset
创建分支（git branch branchName）
niko@niko-notebook:~/StydyGit$ git branch hot_fix
切换分支（git checkout branchName）
niko@niko-notebook:~/StydyGit$ git checkout hot_fix Switched to branch 'hot_fix' niko@niko-notebook:~/StydyGit$ git branch -v # 星号所在分支就是当前分支 * hot_fix bcf8ce2 first reset master bcf8ce2 first reset
合并分支（git merge branchName）
niko@niko-notebook:~/StydyGit$ vim file3.txt # 修改文件
niko@niko-notebook:~/StydyGit$ git status # 查看分支状态
