title: tail -f into grep into cut not working properly
body: <p>i'm trying to build a shell script to monitor some log files.
  I'm using a command like this:</p>
  
  <pre><code>tail -f /var/somelog | grep --line-buffered " some test and p l a c e h o l d e r" | cut -f 3,4,14 -d " "
  </code></pre>
  
  <p>the log file is like:</p>
  
  <pre><code>some test and p l a c e h o l d e r 3
  some test and p l a c e h o l d e r 4
  some test and p l a c e h o l d e r 5
  some test and p l a c e h o l d e r 6
  </code></pre>
  
  <p>and so on..
  My issue is that the output of the command does not display the last line</p>
  
  <pre><code>some test and p l a c e h o l d e r 6
  </code></pre>
  
  <p>until line</p>
  
  <pre><code>some test and p l a c e h o l d e r 7
  </code></pre>
  
  <p>is added to the log.</p>
  
  <p>I hope I made clear my issue.  Can anyone help me to solve this?
  Thank you :)</p>
