title: github commands to update only single file
body: <p>I am beginner for gitHub. I have used svn before but I am not getting grip on github after going through many tutorials on the net. I have no idea about basic work flow. I created clone by using github. If I make any change in file suppose file_A then what is right step to push this file on server:
  I am assuming :</p>
  
  <p>git status->git commit->git pull -> git push</p>
  
  <p>I have doubt that it push all project files on server But i was expecting to update only file_A. Please  suggest me complete command/syntax with file path.</p>
