1 edit | Debian - cron execution orderOn Debian, just suppose I have a crontab for root account like this:
On July 5, 2009 (which is a Sunday), which task will cron execute first? I read man pages for cron & crontab but found no mention of execution order. thanks! | |

@windstream.net | Re: Debian - cron execution order top-down matching on those applicable to the current date/time. If it is 00:00 on July 05, 2009 then:
scriptblablabla1 will execute followed by scriptblahblabla2 | |

| A note to the FreeBSD regarding general Cron behavior states that there is no determination of order for same time cron jobs.
»lists.freebsd.org/pipermail/free···538.html
That makes sense, considering the granularity available to you for scheduling. There are better ways than alpha-numeric sorting to order operations in cron.

@windstream.net | It's not processed alphabetically, it's processed in a top-down order based on the ordering in the respective crontab. Should "bla2" appear before "bla1" in the respective crontab it would be executed first. | |

@windstream.net | Yock has a good point, to be pedantic, it's top-down but execution is done serially, so bla1 and bla2 will run concurrently but when I was debugging cron bla1 is invoked first followed by bla2. | |

Does cron wait for bla1 to finish first before starting bla2? | |

| Re: Debian - cron execution order Understand that it makes no sense for it to wait. If you need one script to finish before another one runs, why not call it from the script you scheduled?
