Writing a cron expression to execute every 15 minutes

I am trying to setup a cron job to run the garbage collector every 15 minutes on my session directory to clean up sessions that are beyond the expiration limit I set in php.ini, in one of my subdirectory locations. I have never used cron jobs before so I was wondering if someone could help me.

What I have so far is:

15 * * * * /home/yadda/something/etc

If you're using anacron (ubuntu default), then the notation is simply */15 as in

*/15 * * * * /home/yadda/something/etc

Visit Cron Maker website if you are using Quartz opensource scheduler.

For every 15 Minute:

0 0/15 * 1/1 * ? *

For Every Day:

0 0 12 1/1 * ? *

The following is an expression that will execute every 15 minutes:

0 0/15 * 1/1 * ? *

So your expression would be:

0 0/15 * 1/1 * ? * /home/yadda/something/etc
