newline - How do I force git to checkout the master branch and remove carriage returns after I've normalized files using the "text" attribute? -

OK, so I've added the file .gitattributes with lines like this

  * .css text * .js text etc ...   
 Then I followed the instructions  
  $ rm Remove git / index # git to reset git to $ git # Scan the working directory $ git position # Show files as normal that add $ git add -u $ git .gitattributes $ git commit -m " Introduce End-of-Line Normalization "  
 but now mer The working copy is still carriage returns! I have unsettled those files which I would like to keep with normalized files, how do I get a git check again in the master branch?  
 I know that the files are normal in the repository, because when I do a repo clone, I have all the files without the carriage return.   
 
 
 Ah! Check the previous commute, then check the master.  
  git checkout head ^ git checkout -f master
