Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have a php script in a web page that needs to run every minute. I'd like to use cron and wget with no output; just hit it and die. In all my research, I've come up with the following and put it in /ect/crontab:
When invoked with this option, Wget will behave as a Web spider, which means that it will not download the pages, just check that they are there. For example, you can use Wget to check your bookmarks:
wget --spider --force-html -i bookmarks.html
This feature needs much more work for Wget to get close to the functionality of real web spiders.
So i took out all the features including dev/null.
I included the direct path and tried it with and without quotes around the url.
Generally, if cron has a problem it'll email the root acct (or whoever owns the relevant crontab).
as the crontab owner eg root
Also, as mentioned try redirecting stdout/stderr to a file until you get it working.
As chrism01 posted, cron should mail you if it has a problem. If that isn't happening for whatever reason, you can try and force it with this (change the path to mail or mailx and the recipient name for your system):
/usr/bin/wget "http://mysite.com/index.php?option=com_acajoom&act=cron" | /usr/bin/mail -s "Output of com_acajoom" root
