On Linux system, there are a lot of commands to shutdown and reboot your system.
This tutorial aims to detail some existing possibilities.
The init_ command interact on the __run level system and announce to each process that the system will restart or shutdown and log this action.
#Restart init 6 #Shutdown init 0
The shutdown command has the same effect as init with the following additional elements :
- warning users of the current action with a display on their terminal,
- forbid new connections to the system,
- program the execution of the command,
- report to processes of extinction with a SIGTERM signal.
#Restart (reboot) shutdown -r #Shutdown now(halt) shutdown -h now #Shutdown at 10:15 / Shutdown in 60 minutes shutdown -h 10:15 shutdown -h +60
The poweroff command is also useful since it allows direct shutdown without the shutdown command actions, which is equivalent to a halt -p:
#Alimentation's shutdown poweroff halt -p
