It is not clear where the extra asterisks came from, but the syntax should be */10 * * * * curl Strictly speaking, it is not 10 minute intervals; it is every multiple of 10. So if you save your crontab at 7:09, the job will still run at 7:10, not 7:19--it won't figure out the current time and run every ten minutes from then.

Re: [CentOS] cronjob not running
Kunle, cron does not have the same environment as the user logged in as root. Specifically, it doesn't have the same 'PATH'. So the safest thing to do, when you refer to an executable such as 'curl' is provide the full path to the executable. If you run 'which curl' at the command prompt it will show the location of 'curl'. Probably it will be '/usr/bin/curl'. I would suggest that you modify the crontab to have the full path.

No surprise, another item for sticklers to complain about. Kind of like top-posting ... complain all we want, somebody will do it, and unless we break their fingers or do it for them they will unintentionally do it. :-/ I'll be most certain to make every attempt not to make use of HTML features in the future.

I don't think being sure that what you write is syntactically correct, and won't break on the OP's system, is being a "stickler". If using HTML formatting actually produces something incorrect when a conversion to plain text is done, that's not a nitpick, it's just wrong, and it could screw up another OP's system much worse. > I'll be most certain to make every attempt not to make use of HTML features > in the future. I figured I should explain why my message unintentionally > showed up with asterisks earlier, but that was a can-o-worms. :( Perhaps, but if you saw that your message actually gave incorrect advice to the OP, you should have corrected it as soon as you saw it. It might not be in time to help the OP, but it would be in time to help other people browsing or searching the mailing list archives. > Now if Google/Gmail could let things be -- and not change my settings back > to HTML from the last time I set it to plain text ... plain text is no > longer an option via the webui, swell. Plain text is the default for me on most messages, but gmail configuration is certainly offtopic for the CentOS list. --keith -- kkel...@wombat.san-francisco.ca.us ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I bloody said why the asterisks were inserted and it was not _intentional_. I loathe that this happened because this is a total waste of your and my time. This sets a precedence for me - read on the list and don't reply often (or at all).

I recently discovered a logwatch setup that worked fine on C5, but parts of it were silently failing on C6. Running logwatch from cron was producing different output to running it on the command line. It took a while before it occurred to me to check selinux.
