I was frustrated that recurrent jobs are not running like I want via the [cron](https://man.openbsd.org/cron) on my laptops. I was looking for something which trigger actions every hours the machine is running, or once every day, or once every week. For a daily task, it doesn't matter if we are the morning or the evening. For a weekly task doesn't matter if we are saturday, sunday or monday. So I wrote a quite simple shell script dealing with this job, I've called it "vdcron" **Note of 2024/11/10**: This post has few days, and I receive questions about "why not anacron?". So, I've just completed this post with this aspect.

I'm a big fan of cron on my servers to trigger several tasks: monitoring reports, backups, security checks, ... But I was annoyed that on laptops such tasks are not possible. Mainly because the laptop does not always run, or is not always connected to the correct network. So, as explained in one of my previous [blog](http://www.vincentdelft.be/post/post_20180521), existing solution does not fully fit my needs. So, vdcron was born. This blog mark the release 0.5.3 of vdcron

I was looking for a simple cron like tool that help me to perform tasks on one specific day on my laptop and desktops. Unfortunately the embedded cron in OpenBSD is not foreseen for workstations or laptop that we shutdown (or hibernate) regularly.
