title: Show ip address when os boot
body: <p>I want to make when CentOS start in init 3 to show me my ip addr, before log in.
  For Example:</p>
  
  <pre><code>CentOS Realese 6.5(Final)
  Kernel 2.6..
  ip addr: 192.168.1.1
  </code></pre>
  
  <p>or something like that.</p>
  
  <p>I make script which is:</p>
  
  <pre><code>    #!/bin/bash
      ifconfig eth0 | grep 'inet addr'
  </code></pre>
  
  <p>but, I don't know where I put it.</p>
  
  <p>I try in rc.local (with "cat" and him path) but obviously it is not right place, or I make something wrong.
  And I try in /etc/issue , but and there maybe I make something wrong.</p>
