title: How to find a Git hash from Git commands?
body: <p>I have a list command from some source code:</p>
  
  <pre><code>git clone https://github.com/BVLC/caffe.git
  cd caffe
  git checkout 8c66fa5f3c04e -b unet_patch
  git cherry-pick 458928a
  </code></pre>
  
  <p>I know that the first line will clone a recent version of Caffe code. However, the third and fourth lines will modify the source code. I do not know what <code>8c66fa5f3c04e</code> and <code>458928a</code> are. From these numbers, can I find the Git hash of the Caffe code?</p>
