David Cantrell 🏏Today I hate <a href="https://fosstodon.org/tags/InnoDB" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#InnoDB</a> fragmentation, and incompatible <a href="https://fosstodon.org/tags/crontab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#crontab</a> files across different versions of <a href="https://fosstodon.org/tags/cron" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cron</a>

Martin PughHay there fediverse. Do we have any <a href="https://bsd.network/tags/bash" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#bash</a> <a href="https://bsd.network/tags/cron" class="mention hashtag" rel="nofollow noopener noreferrer" 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.

NormI've had my <a href="https://fosstodon.org/tags/crontab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#crontab</a> setup for ages to execute `trash-empty 30` (from the <a href="https://fosstodon.org/tags/TrashCLI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TrashCLI</a> package) each day, but just realised it hasn't been working.Running manually shows a confirmation prompt, so I assume that's the reason. Apparently trash-empty can detect when it's in interactive mode, but this appears to be buggy.Thankfully there's an `-f` flag to force the command with no prompt, so changing my crontab to `trash-empty -f 30` hopefully works instead.<a href="https://fosstodon.org/tags/Bash" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Bash</a> <a href="https://fosstodon.org/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> <a href="https://fosstodon.org/tags/Cron" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Cron</a>

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 noreferrer" target="_blank">#rsync</a> <a href="https://mastodon.social/tags/cron" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cron</a> <a href="https://mastodon.social/tags/macOS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#macOS</a> <a href="https://mastodon.social/tags/security" class="mention hashtag" rel="nofollow noopener noreferrer" 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. A modern approach to running cron-like job-scheduling.<a href="https://yieldcode.blog/post/working-with-systemd-timers/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://yieldcode.blog/post/working-with-systemd-timers/</a><a href="https://mstdn.social/tags/cron" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cron</a> <a href="https://mstdn.social/tags/backups" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#backups</a> <a href="https://mstdn.social/tags/SelfHosting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SelfHosting</a> <a href="https://mstdn.social/tags/server_management" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#server_management</a> <a href="https://mstdn.social/tags/homelab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#homelab</a>

ferricoxideA couple months back, I bought an external (Samsung) USB SSD. It's a bit aggressive about spinning down for power-saving.
