比较差异：git diff
提交到本地仓库：git commit -a -m "xxx"
提交到远程仓库：git push origin develop
创建分支: git branch branch1
进入分支: git checkout branch1
创建并进入分支: git checkout -b branch1
将本地分支进行改名: git branch -m old_branch new_branch
将本地分支的远程分支删除: git push origin :old_branch
将改名后的分支push到远程，并让本地分支关联远程分支： git push --set-upstream origin new_branch
