anchor.diff:   :~/Calavera$ vagrant ssh manos5

    vagrant@manos5:/home/hijo$ git checkout -b feature/add-numbers master
  - Switched to a new branch 'add-numbers'
  + Switched to a new branch 'feature/add-numbers'
   
   You have added a new branch and switched to it. You can test this:
   
  
positive.code: Switched to branch 'master'
  vagrant@manos5:/home/hijo$ ls
  build.xml  src  target
  vagrant@manos5:/home/hijo$ git checkout add-numbers
  Switched to branch 'add-numbers'
  vagrant@manos5:/home/hijo$ ls
  build.xml  src  target  x
  
  ....
  
  See how that works? The file "x" is visible in the "add-numbers" branch, but not in the master branch. Delete it:
  
   vagrant@manos5:/home/hijo$ rm x
  
  
negative.code: Your branch is up-to-date with 'origin/master'.
  vagrant@manos5:/home/QA/hijo$ git pull
  Already up-to-date.
  vagrant@manos5:/home/QA/hijo$ git pull origin feature/add-numbers
  From ssh://cerebro5/home/hijo
   * branch            feature/add-numbers -> FETCH_HEAD
