title: Git how to update local repository and keep my changes
body: <p>OS: ubuntu 16</p>
  
  <p>I use git clone for copy remote repository to my local machine.
  I made some changes (via nano) in some code lets say in 5-10 files (repository have more then 2000 files i think).</p>
  
  <p>But now this repository get some nice updates. And i want get all this updates, but i want keep my custom changes. I cant commit to this repository because i believe my code and fixes are "bad" and not perfect.</p>
  
  <p>Which command i should use to get all updates and keep my changes in files?</p>
