title: error while executing lua script for redis server
body: <p>I was following this simple tutorial to try out a simple lua script</p>
  
  <p><a href="http://www.redisgreen.net/blog/2013/03/18/intro-to-lua-for-redis-programmers/">http://www.redisgreen.net/blog/2013/03/18/intro-to-lua-for-redis-programmers/</a></p>
  
  <p>I created a simple hello.lua file with these lines</p>
  
  <pre><code>local msg = "Hello, world!"
  return msg
  </code></pre>
  
  <p>And i tried running simple command</p>
  
  <pre><code>EVAL "$(cat /Users/rsingh/Downloads/hello.lua)" 0
  </code></pre>
  
  <p>And i am getting this error</p>
  
  <pre><code>(error) ERR Error compiling script (new function): user_script:1: unexpected symbol near '$' 
  </code></pre>
  
  <p>I can't find what is wrong here and i haven't been able to find someone who has come across this. </p>
  
  <p>Any help would be deeply appreciated. </p>
