linux - Scheduling scripts with variable frequency -


i want run python script on ubuntu 14.04 server following frequency:

  • monday friday:
    • from 0800 hrs 1600 hrs: run once every hour
    • from 1600 hrs 2300 hrs: run once every 30 minutes

  • saturday , sunday:

    • from 0800 hrs 2300 hrs: run once every 2 hours

  • at other times, don't run

is possible cron? if not, can suggest alternative?

as suggested in comments, adding these cron entries do: (lines starting # comments)

# monday friday, 8 4 pm, once every hour 0 8-16 * * 1-5 <command> # monday friday, 4 pm 10 pm, twice every hour 0,30 17-22 * * 1-5 <command> # saturday sunday, 8 11 pm, once every hour 0 8-23 * * 0,6 <command>
