Cron Issues

By Erik Letson, July 20th, 2020 (blog index)

Recently, I was in the process of implementing an automated system on my server to accomplish some repetitive task. As is usual for jobs like this, I was using cron, as I had done many times before. The script that I was having cron run was a good bit more complicated than most other cron scripts I had run before, but I didn't expect it to be too much trouble, especially coming from cron's end. Boy was I wrong...

The specific ways I got my script working are not really what I wanted to post about here. Rather, in the course of researching my problem, I learned lots of little caveats that have to do with cron in general, and I tought I would compile them here, for my use and others'. If you are having difficulties getting cron to obey you, maybe some of the pointers here can help.
