title: Pipe data to redis
body: <p>When I pipe the echo to redis client, I get an error.</p>
  
  <pre><code>[root@server ~]$ echo "abc43345" | redis-cli set my_passwd2
  (error) ERR wrong number of arguments for 'set' command
  </code></pre>
  
  <p>But the following works as expected.</p>
  
  <pre><code>[root@server ~]$ redis-cli set my_passwd2 `echo "abc43345"`
  OK
  </code></pre>
  
  <p>Is there any way to make the first example work?</p>
