title: grep command on Solaris 9
body: <p>I faced a strange behavior of a grep command on Solaris 9.
  For example , I have a host file with two lines:</p>
  
  <p>1.1.1.1 host</p>
  
  <p>1.2.3.4 host-MY</p>
  
  <p>I'd like to grep the line contains host string only (not the other line that contain host-MY)</p>
  
  <p>I use:
  grep -Fxq host /etc/hosts</p>
  
  <p>but I receive</p>
  
  <p>grep: illegal option -- F</p>
  
  <p>grep: illegal option -- q</p>
  
  <p>grep: illegal option -- x</p>
  
  <p>in spite of the fact that this options I can find in grep manual on my Solaris machine  </p>
