title: In Git, what is the difference between origin/master vs origin master?
body: <p>I know, <strong>origin</strong> is a term for the remote repository and <strong>master</strong> is the branch there.</p>
  
  <p>I am purposely omitting the "context" here and I am hoping that the answer should not depend upon the context. So in git command lines, what is the difference between <strong>origin/master</strong> and <strong>origin master</strong>.  Is there a non-ambiguous way to understand when to use <strong>origin/master</strong> and when I should use <strong>origin master</strong>?</p>
