Install cron-Run regular program

Let's install cron . Cron is a resident application for executing periodic programs. I think it is installed by default, but if it is not installed, follow this procedure to install it. Use the apt command.

sudo apt install -y cron

Check systemctl that cron is installed and running.

sudo systemctl status cron

If you see active, cron is installed and running.
