[CentOS] Single crontab entry for every 15 minutes beginning & ending on the hour
We have a cron job that needs to run every 15 minutes throughout business hours. The first run is at 8:00, the last run is at 17:00. Is it possible to specify this time range in a single line? */15 8-17 * * 1-5 will run 8:00 - 17:45. That's not what I want. Likewise */15 8-16 * * 1-5 will have the last run at 16:45, not 17:00 This is more of a brainteaser than a real problem. I can easily configure the job with multiple entries, but I'm a little obsessive-compulsive so I want to try to do it with one entry. # rpm -qa vixie-cron vixie-cron-4.1-49.EL4 -- Jeff

You can do it with a bit of shell too: */15 8-17 * * 1-5 [ `date +\%H\%M` -lt 1715 ] && /do/my/job.sh Cheers Tony -- Tony Mountifield Work: tony at softins.co.uk - http://www.softins.co.uk Play: tony at mountifield.org - http://tony.mountifield.org
