reboot: Halt the system (same as `halt`).
$ reboot --halt
try on your machine
The command "reboot --halt" is used to initiate a system shutdown and stop all processes running on a computer.
When you execute this command, the "reboot" part indicates that the system will restart once it is halted. The "--halt" option specifies that the system will shut down completely rather than just halting or suspending it.
During the shutdown process, all running processes are terminated, and the operating system ensures that all data has been safely written to the disk before the system powers off. Once the shutdown is complete, the computer will either turn off or restart depending on its configuration.
