title: Turn off crontab log
body: <p>The log file is located at <code>/var/log/cron</code>. Its size grows too fast and it seems to contain a lot of unimportant data that I would never want to see. So I try to find a way to turn it off but still don't know how.</p>
  
  <p>Here are some more details about the crontab:</p>
  
  <pre><code>crontab -l
  */5 * * * * /usr/sbin/ntpdate 10.0.1.10
  */1 * * * * cd /tmp &amp;&amp; netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c &gt; net.tmp &amp;&amp; mv -f net.tmp net.cache
  */1 * * * * /script/svrcheck/openvpn.sh &gt; /dev/null 2&gt;&amp;1
  
  
  tail /var/log/cron
