In this lesson we are going to explore Linux task scheduling.
So what are the options?
First option is Cron. That's a classical solution. It allows you to schedule recurring tasks.
It has been around forever and it uses a Chrome daemon and you can use crontab e to edit the tasks.
Then there is add is for tests that you need to run once only.
That's a fun little solution. It's not used that much but it might be convenient if you want to
use it. Make sure that the D daemon is started and use on the command line to schedule tasks.
Then there is a newer solution which is the systemd timer.
So systemd timers are the new alternative to CRON and on some distributions
like Red Hat you will see that timers are used instead of Cron.
They create a timer unit and these timer units are used using systemctl.
In the next couple of videos we will explore how it works.
