Most of us shutdown
our computers using the power button given in the Start menu. Some of
us use the physical power button on our machines. Very few people
actually use other means of shutting down a computer and even less is
the number of people who use the command prompt to shutdown a computer.
A reason for this is that most of us don't know that the command prompt
can be used to not only shutdown, restart or log off
our computer
instantly but also to shutdown a remote computer provided you have
administrative access. It can also be used to hibernate a computer and
give a comment containing the reason for shutdown. This post will show
you how to do all this.
Required
A computer running Windows (XP, Vista, 7 or 8) with the command prompt working perfectly, i.e. not disabled by a virus
Initial Steps
1) Press Windows Key + R.
2) Enter CMD and press Enter.
This will start the command prompt. Follow the instructions below depending on what you want to do.
Shutdown Local Machine (Your Computer)
Type "shutdown -s" without the quotes in the
command prompt and press Enter. Shutdown is the command being executed and the switch -s tells the computer to shutdown.
Restart your Local Computer
Type "shutdown -r" in the command prompt and press Enter. In this case,
the command switch -r is telling the computer to restart after shutdown.
Log Off the Current User
Type "shutdown -l" in the command prompt and press Enter. The -l command switch tells the computer to log off.
Shutdown a Remote Computer
Type "shutdown -s -m \\name of the computer" in the command prompt and
press Enter. Replace \\name of the computer with the actual name of the
remote computer you are trying to shutdown. As mentioned earlier,
you must have administrative access to the computer you are trying to
shutdown. To know if you have administrative access, press Windows key +
R and then type the name of the computer and press Enter.
Note: If you don't remember the name of the remote computer, you can
look for it by opening a list of all the computers you are connected to
by executing "net view" in command prompt.
If you can connect to the computer, you will be asked to login with your
username and password. Upon entering them, a window will display the
list of all the directories available to you. This should help you know
whether you can or cannot shutdown the remote computer.
Hibernate a Local Computer
Type in "Rundll32.exe Powrprof.dll,SetSuspendState" without the quotes
and press Enter. Your computer should hibernate, if it does not, then
you must enable hibernation to do this.
Shutdown your or a remote computer after a specific time
Type "shutdown -s -t 60" to shutdown your computer after 60 seconds.
Upon executing this, a countdown timer displaying a warning message will
be shown. This command uses the -t command switch followed by a
variable (which is 60 in this case) which represents the number of
seconds after which the computer will shutdown.
Display a Message containing the reason for shutdown
Type
shutdown -s -t 500 -c "I am tired. I don't want to work anymore."
(with the quotes) in the Command Prompt and press Enter. The -c switch
is used in the code to give the reason for shutting down and what is
followed in quotes will be displayed in the dialog box as the
reason. This can be used to display all sorts of funny messages.
One example :-
Skynet has become self aware. John Connor did not stop me. You can not use your PC anymore.
Stop a System Shutdown
Type "shutdown -a" and press Enter. This will stop the system from
shutting down if the countdown to shut down has not reached 0.
