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

      I didn’t say it is not a good solution. It’s a legacy solution replaced by systemd timers.

      With systemd timers you’re entirely more flexible and timers run much more reliable. You also get proper logging and you cleanly separate program execution and scheduling of program execution. And since timers aren’t crammed all in one file line-by-line you can independently version them using Git or backup individual timer configurations.

      If you don’t care for that and don’t really care if a job gets executed reliably and don’t want to specify precisely when (on startup, on shutdown, specific time, repeatedly, etc.) a program is executed, just go with cron - you might need to install a cron daemon and set up the needed service in systemd first.
