 |
|
My cron.weekly jobs prevoiusly ran on Saturdays, which was the most convenient day for me. Now they run on Sundays for some unknown reason. Similarly, my monthly cron jobs seem to run near the end of the month, not at the start, as desired. I'm using pretty much the default configuration of cronie.
I'd like my weekly jobs to run on Saturday, and monthly jobs to run on the first day. How to I configure this? It used to be easy with vixie-cron using /etc/crontab. |

/etc/cron.d/dailyjobs might contain the answer.
Anyway, cron and anacron work in different ways:
cron triggers jobs exactly _on_ the specified _time_, and anacron triggers jobs _after_ the specified _delay_. If you want your jobs to run on a specific day of a month, put them in as crontab jobs with a trigger time and not as anacron jobs running on interval.

Thanks. Just checking:

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
5 2 * * * root cd / && run-parts --report /etc/cron.daily
47 4 * * 7 root cd / && run-parts --report /etc/cron.weekly
52 6 1 * * root cd / && run-parts --report /etc/cron.monthly

| Code: | # For details see man 5 crontab
# Example of job definition:

You weekly jobs are set to run on sunday so that matches your findings, your monthly jobs are set to run on day 1 of month.
I don't really know anacron - but going from the config it seems to say to only start jobs between 3 and 22 and with a random delay of 45 minutes - ie. you hourly jobs will not start at 02:05 but at 3:00 (dunno if the delay is added to that or to the 2:05 requested in dailyjobs?) - I would guess |
