Cron jobs, strange minute parameter?

[johnd0827]

Hi everyone,

First, please forgive me if this is a simple question, but I've just been given a linux box that I need to maintain now, and of course there are problems with it.

I also haven't had to administer a linux box in YEARS, so I'm very rusty.

My question...

There's a cron job that runs, and the way the job was set up confuses me. Here's the line (this is displayed from crontab -l command)

*/15 * * * * /usr/local/backer/utils/crontask.sh $2>1 > /dev/null

What I don't understand is the */15 parameter. I know this is supposed to be the minutes value, but I don't know what this */15 syntax means.

Thanks in advance for any help!
John.

I found the answer.

man crontab

To finish this thread...

*/15 means to run every fifteen minutes.
