I have been asked to tune up a server that keeps crashing. I'm looking at the cron jobs and found this one:
* 3 * * * wget -O /dev/null "http://www.domain.com/index.php?option=com_acymailing&ctrl=cron" > /dev/null 2>&1
Aside from invoking a PHP script by calling wget to the local web server and routing the output to dev/null, I'm wondering if there are other problems.
1) Am I correct in thinking that this script will run every minute from 3am to 4am? The pattern is *3***.
2) What does the 2>&1 bit at the end do?
Any help would be much appreciated.
