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
Crontab is deprecated,theres a better way now. Dont ask me though because im working on servers that havent had an upgrade in 10+ years
My servers are up to date and there is not a single Linux distro that has removed cron or marked it for removal yet. Probably will stay that way for a long time.
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…
You mean running systemd timers? Yes, they are great, but for a beginner I think understanding crontabs is still better.
Also, who said crontabs are deprecated? Do you have a source for that?
Idk i remember reading that theres a new way. Maybe it isnt deprecated? Yes systemd timers is the new way
systemd timers are not actually universal. not everyone uses systemd, some use sysvinit, openrc, etc. systemd timers are also much more difficult to set up.
cron is not “deprecated” and is still widely used industrially and locally.
