创建本地分支并跟踪到远程分支

git checkout -b <local_branch_name> <remote_branch_name>

切换本地分支

git checkout <local_branch_name>

查看全部分支

git branch -a

查看本地分支状态

git branch -vvv

合并（把指定分支的内容合并到当前分支）

git merge <local_branch_name>

提交

Git add 这个命令是将工作区内容提交到暂存区
Git commit 这个命令是将暂存区内容提交到本地分支
Git push 是将本地分支内容提交到对应的远程分支
