Question

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 

Answer 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
