Sometimes you want to list the jobs you scheduled (reboots) for a Red Hat Enterprise Linux 7 server. This is how you can list the shutdowns:
root@tasus:~# shutdown -r 19:02 "This system will reboot at 19:02 for updates"
Shutdown scheduled for Tue 2016-09-20 19:02:00 CEST, use 'shutdown -c' to cancel.
root@tasus:~# systemctl status systemd-shutdownd.service
