I'm trying to get a cron job to run every 5 min on my localhost. Using the Cronnix app I entered the following command

0,5 * * * * root curl http://localhost:8888/site/  > /dev/null

The script runs fine when I visit http://localhost:8888/site/ in my browser. I've read some stuff about getting CI to run on Cron, using wget and various other options but none make a lot of sense.

In another SO post I found the following command

wget -O - -q -t 1 http://www.example.com/cron/run

What is the "-O - -q -t 1" syntax exactly?

Are there other options?
