cron jobs configuration

I just checked my cPanel and see there are no cron jobs set up.... What are the basic and needed cron jobs to set up to make the site run smoothly and to do the automatic updates and etc. 

Any advice is appreciated! 

this is what I have set for every miute:

cd /home/blahblah/public_html/periodic; /usr/local/bin/php -q cron.php

Thank you, what parts of that cron job would i need to change to work for my domain?

Here is something I wrote a long time ago that may help you: (pay attention to the bold. it answers your question)

Here are some helpful tips regarding Cron Jobs-

Most common configurations:

* * * * * /usr/local/bin/php -q /home/sitedir/public_html/periodic/cron.php

* * * * * /usr/bin/php -q /home/sitedir/public_html/periodic/cron.php

(to find your exact /home/sitedir/public_html/ edit your /inc/header.inc.php and look for $dir['root'])

-I have also found that some Crons (depending on your host) have difficulties "calling" the cron job to run. I have been able to resolve this by specifying the location of the php configurations and manually entering it into the cron job command: (See below)

* * * * * /usr/bin/php -c /home/sitedir/public_html/php.ini -q /home/sitedir/public_html/periodic/cron.php
