cronie

In archlinux, using crontab need to install a package named cronie

sudo pacman -S cronie

make it start at boot and start it

sudo systemctl enable cronie
sudo systemctl start cronie

edit crontab with vim, because default editor is vi

EDITOR=vim crontab -e

list all crontab

crontab -l

it seems that cannot use notify-send command and i don’t know how to resolve it.
