In Kali Linux, the shutdown command is used to stop (halt), shut down (power off) or restart (reboot) the system.
1 Grammar format
The syntax of the shutdown command is as follows
shutdown [OPTIONS] [TIME] [WALL]Among them, OPTIONS represents the parameter; TIME represents the specified time; WALL represents the displayed information.
2 Introduction to OPTIONS
2.1 Stop the system
The -H or --halt parameter means to stop (halt) the system.
Figure 1 Stopping the system
It should be noted that using the -H parameter requires administrator privileges, so add "sudo" before the shutdown command, and you need to enter the administrator's password after pressing Enter. After pressing Enter again, it will display that the system will stop, as shown in Figure 1.
2.2 Shut down the system
The -P or --poweroff parameter indicates to turn off (power off) the system, as shown in Figure 2.
Figure 2 Shut down the system
Using the -P parameter does not require administrator privileges. After entering the command and pressing Enter, the message that the system will shut down in one minute will be displayed, as shown in Figure 2.

When running Kali Linux in a VMware virtual machine, after halting the system, Kali Linux will stop in the interface shown in Figure 3.
Figure 3 halt system
At this time, you need to click "Close Client" in the toolbar of the VMware virtual machine to shut down the system, as shown in Figure 4.

After the poweroff system, Kali Linux will shut down directly without manual shutdown again.
2.3 Restart the system
The -r or --reboot parameter indicates to restart the system. Using the command shown in Figure 5, the system can be restarted.
