linux常用命令

###git
在github上参与别人的项目或则多人共同开发一个项目的话，fork一个项目的仓库过来，自己做完提交pull request之后，就等着作者review过之后进行merge了。但是之后作者再进行新的改动，我的分支上还是原样，那么怎样让把我的分支上的与最新的仓库一直呢?

#assume you originally cloned from your forked repo,that remote will be called "origin", 
#then you need to add firstguy repo as another remote
git remote add firstguy git://github.com/firstguy/repo.git
#After that is all set up, you should indeed be able to
git pull firstguy mastergit push origin
