branch

1、删除分支

git branch -d branch_name
error: The branch 'branch_name' is not fully merged.
If you are sure you want to delete it, run 'git branch -D branch_name'.

2、重命名分支

 git branch -m ord_branch_name new_branch_name

3、比较分支的不同

git diff branch1 branch2 .  branch1和branch2 的不同 
git diff branch_name  . branch_name 和当前分支的不同

4、剪切别分支的文件

git checkout master -- xxx/xxx.txt
