How to reboot or shut down a Mac via terminal

[berndschimmer]

Hi,

i'm trying to get back the old keyboard shortcuts for reboot and shut down on a Mac keyboard.
What I tried as a simple start is remap the f13 key to a shell command "reboot" or "sudo shutdown -r now".
For both commands I need sudo rights. Is this even possible with karabiner elements and if yes, how?
Thanks for the help.
