There are times you (as a system Administrator) may want to reboot your PC due to undesired behavior on your PC. During and after the installation of new programs (software and hardware), most times, you may need to restart your device. This will shut off all processes so that the Kernal can be re-established with the new software or hardware. Here are some useful switches (flags) that can be combined to shut down or restart a computer.

Here's how to do the shutdown functions via a the CLI (batch file):
shutdown -r — restarts
shutdown -s — shutsdown
shutdown -l — logoff
shutdown -t xx — where xx is number of seconds to wait till shutdown/restart/logoff
shutdown -i — gives you a dialog box to fill in what function you want to use
shutdown -a — aborts the previous shutdown command....very handy!
shutdown -h — hibernate. Easy mistake - it's not for help

Additional options:
-f — force the selected action
