You can easily stop, shutdown, and restart the Linux operating system using the shutdown command and its various options.The Linux shutdown command is entered on the Linux terminal that is started by using the keyboard shortcut [Ctrl] + [Alt] + [T].Basic Linux shutdown commands the shutdown command is required to shutdown or restart Linux on a terminal.We can add an option to it, then a time specification and a message.The syntax for Linux shutdown commands is as follows: shutdown [OPTION] [TIME] [MESSAGE] For each of the commands listed here, there is at least one alternative that produces the same result.The standard command to shutdown Linux, shutdown -hlinux, will shutdown in a minute.The -h option explicitly shuts down or shuts down the system.You can usually produce the same result by entering the close command separately.Shutdown The standard command for restarting Linux, shutdown-rlinux, will restart in one minute.The -r option stands for restart or restart.The shutdown -h 0Linux command shuts down Linux immediately.In this case, the close command is followed by the “-h” option and the time specification “0”, which means immediately.Here is another, more common command to shutdown Linux immediately: shutdown now the command shutdown -r 0Linux will restart immediately.In this case, the close command is followed by the “-r” option and the time specification “0”, i.e., immediately.The following are common commands to restart Linux immediately: shutdown -r now The standard Linux shutdown command with a one-minute delay is particularly useful for multi-user solutions, that is, when multiple users are accessing a Linux computer or server.In this case, the network administrator can set up a warning message as a wall message to inform the user that the system will be shut down or restarted soon.If Linux is only used on a single machine, the commands to shut down or restart Linux immediately are usually just as simple.Scheduling Linux shutdown or reboot We can also easily schedule Linux shutdown or reboot to occur at a specific time or after a specific time.To do this, we must add minutes or time after the corresponding Linux shutdown command, as shown in the following example: shutdown -h 20 Linux will be shutdown 20 minutes after you enter the command.The following commands are more commonly used and have the same result: shutdown + Command to restart Linux in 2020 minutes Shutdown -r 20 Linux will be restarted 20 minutes after you enter the command.You can also use the plus sign in this command.Shutdown -r +20 run the shutdown -h 17:30 command to shutdown Linux at 5:30 p.m. Time specifications are based on the 24-hour format in Linux, which complies with hh:mm.In this case, Linux shuts down at 5:30 p.m. (17:30).Again, we can omit the “-h” option that represents shutting down or powering down the system: shutdown -r 17:30Linux will be rebooted at 5:30 p.m.In this case, the “-r” option for “reboot” obviously can’t be omitted — otherwise, Linux will shut down without a reboot.Linux Shutdown – Additional Commands In addition to the Linux shutdown commands mentioned earlier, there are many other commands and options available to stop, shut down, and restart the Linux operating system.These can also often be used in conjunction with scheduled Linux shutdown commands.There is a difference between “stop the system” and “shut down the system”.When it is stopped, all processors (cpus) stop, but when it is turned off, it is also disconnected from the main power supply.Generally, the term “shutdown” is understood to mean the shutdown and power outage of the system.Linux shutdown -p This command shuts down the system and cuts off the main power supply.Shutdown ‘WRITE YOUR WALL MESSAGE HERE’ WALL messages are messages displayed on the operating system user’s screen.For example, administrators can use wall messages to notify users that the system is shutting down.The shutdown -c command is used to cancel the scheduled shutdown or restart.
