Martin PughHay there fediverse. Do we have any <a href="https://bsd.network/tags/bash" class="mention hashtag" rel="nofollow noopener" target="_blank">#bash</a> <a href="https://bsd.network/tags/cron" class="mention hashtag" rel="nofollow noopener" target="_blank">#cron</a> experts that can help me figure out how to fix things?TL;DR - I need to reference the `$USER` variable as a parameter in a shell script that forms part of a dynamic path in a backup routine (the location varies by host so trying to automate as much as possible). Running the script as a logged in user over SSH works perfectly but when I add a crontab entry under the same user to run the same script is fails to parse the `$USER` part so the destination is incorrect and it throws an error.I should also note that if I specify the path manually in the script it also works, but then it's a pain to automate across different hosts so I'm trying to avoid that if possible.I now been going round in circles trying to figure this out for a couple of days so it's time to ask for help.

Pete Prodoehl 🍕I forgot you can't just run a shell script with rsync calls via cron on macOS because of... security. I think my workaround will do though.I write a shell script and then create an Automator application that calls the shell script. I then add a cron job to open the application. I need to check if it runs when the screen is locked. I'm pretty sure it does but I will test again.<a href="https://mastodon.social/tags/rsync" class="mention hashtag" rel="nofollow noopener" target="_blank">#rsync</a> <a href="https://mastodon.social/tags/cron" class="mention hashtag" rel="nofollow noopener" target="_blank">#cron</a> <a href="https://mastodon.social/tags/macOS" class="mention hashtag" rel="nofollow noopener" target="_blank">#macOS</a> <a href="https://mastodon.social/tags/security" class="mention hashtag" rel="nofollow noopener" target="_blank">#security</a>

Dmitry KudryavtsevSo I needed to run some periodic backup jobs, both for personal and professional needs. If were you ever tasked with such a request, you probably looked at cron. But cron has shortcoming: it does not survive power off events, it does not support any logs, and you can’t easily tell when, and if it was ran.Meet systemd timers.
