I am on Mint XFCE and Redshift is just so inconsistent and I have tried its forks, also inconsistent. So instead I have been using sct in the terminal to adjust the temperature, and have set a command that resets it back to normal every time that I log on. However, I was wondering if there is a way to make it so that “sct 2750” runs every day at 10 pm or during a specific period of time.
Edit: I figured out the solution which was to create a crontab with the following line in it: 0 22 * * * env DISPLAY=:0 XAUTHORITY=$HOME/.Xauthority /usr/bin/sct 2750
Yes, it’s usually still available, but systemd timers are the more “modern” way, which is why distros like Arch use them by default:
https://wiki.archlinux.org/title/Cron
that’s because we’ve understood there’s a line between what is reasonable for most users to implement - cron - and what is more reasonable for the OS to implement - systemd timers.
you don’t want a user who doesn’t know what they’re doing to accidentally brick a key OS timer (for instance, when they’re setting up their own), so systemd helps to segregate while still allowing experienced users to easily stop timers.
meanwhile, for users, cron is much easier to work with…
