دوست عزیز با دستور shutdown تو تمام توزیع های گنو لینوکس می تونی سیستم Halt, power-off,reboot کنی.
توی ترمینال بنویس :
[tazik@localhost ~]$ shutdown --help
shutdown [OPTIONS...] [TIME] [WALL...]
Shut down the system.
--help Show this help
-H --halt Halt the machine
-P --poweroff Power-off the machine
-r --reboot Reboot the machine
-h Equivalent to --poweroff, overridden by --halt
-k Don't halt/power-off/reboot, just send warnings
--no-wall Don't send wall message before halt/power-off/reboot
-c Cancel a pending shutdown
