[opensuse] How to set the time when cron.daily executes ?
Hi, how can I set the time when cron.daily executes ? On earlier setups of OpenSuse the scripts in /etc/cron.daily ran very late at night which is OK. On my latest setup they get started at 09:45am. Can I set it back to 04:00am ? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

DAILY_TIME="" That is one problem with using distribution value-add to system tools. They are not documented in the man pages. "man cron" would not have told you about run-crons. It would have told you about /etc/crontab and you could have seen run-crons there, but then "man run-crons" does not exist so you are left having to do what I did above, actually go look at the file and hope it's a script and not a binary, and hope you can read the script language well enough to make some sense of it. I'm sure suse documents this somewhere, but apparently you couldn't find it, so it wasn't in a very good spot, because you did at least try, right? -- bkw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Why not "Don't bother"? If you want to run a script late at night, why put it in cron.daily? Why not make a separate crontab entry for it that has it run late at night? Take it out of cron.daily and put it in a separate file. -- They say that if you play a Win cd backward you hear satanic messages. That's nothing!
