Add the below line (with tweaks) to the end of /etc/crontab
:
30 23 * * * root shutdown -h now
At 23:30 (11:30 PM), the kiosk will shut down. No matter what user is logged in, the shutdown command runs as root.
(If you don't want to use the global crontab, log in as root and use
crontab -e
. Use the same above syntax without the
root
).
Cron Format:
MM HH DD OO WW command
MM
: Minute, 0-59
HH
: 24-hour hour
DD
: Day of month
OO
: Month
WW
: Day of Week (Sunday is 0, Monday is 1)
command
: Self-explanatory
如在22:00自动关机:
00 22 * * * root shutdown -h now
