title: System call in Ruby
body: <p>I'm a beginner in ruby and in programming as well and need help with system call for moving a file from source to destination like this:</p>
  
  <pre><code>system(mv "#{@SOURCE_DIR}/#{my_file} #{@DEST_DIR}/#{file}")
  </code></pre>
  
  <p>Is it possible to do this in Ruby?  If so, what is the correct syntax?</p>
