ray@ray-ubuntu# git branch --set-upstream-to=origin/dev dev
Branch dev set up to track remote branch dev from origin.

恢復當前版本到某次提交的版本，使用commit記錄值的前幾位就可以了
ray@ray-ubuntu # git reset --hard 62042
HEAD is now at 6204280 fix sted timestamp'0' erro
查看當前分支：
ray@ray-ubuntu ~/P/helloworld> git branch -l
* dev
master
刪除之前追蹤的某個文件：
git rm -rf --cached /path/to/file
git add .
git commit "xxxx"
