Is it possible to add a line to a crontab to so that a program will run every 15 minutes? how will this line look?

Thank you.

every 15 min 24/24 ?
This is every 10 min, so I let you figure out 15...
Code:
05,15,25,35,45,55 * * * * /usr/sbin/dmesg - >>/var/adm/messages 2>&1

crontab

Should run every 15 minutes 24 hours a day, 7 days per week.

15 * * * * /bin/nnkill

Cron

Ups ... I realized the logic:

10,25,40,55 * * * * /bin/nnkill

No, the above runs at 15 minutes after the hour, every hour, not every 15 minutes

Thank you.
The crontab entry below runs every 15 minutes, 24 hours a day, every day of the year.
Code:
*/15 * * * * /usr/sbin/dmesg - >>/var/adm/messages 2>&1

Cron

10,25,40,55 * * * * /bin/nnkill

The above should work.

Do I have to leave a space after each comma?
I read somewhere that if crontab file is not formated properly it will be deleted. Is this true?
