title: redis-cli and value from a file
body: <p>Is it possible to easily set specific value from a file using interactive <code>redis-cli</code>?</p>
  
  <p>I'd like to achieve same result as with following Python snippet:</p>
  
  <pre><code>with open("some.jpg") as f:
      image_binary = f.read()
  
  rd.hset("some_key", "image_binary", image_binary)
  </code></pre>
