title: Saving the entire git diff between two commits in a text file
body: <p>is there a way where I could save the entire difference between two diff in a text file?</p>
  
  <p>Suppose I wanted all the changes between <code>A1</code> and <code>A10</code> on <code>master</code> branch.</p>
  
  <pre><code>--A11-A10-A9-A8-A7-A6-A5-A4-A3-A2-A1-master
  </code></pre>
  
  <p>Or, is there a way where I could get the entire diff in Terminal which I could copy+paste?</p>
