http://www.itechster.com In this tutorial we will go over on how to use the init command in Linux. This is very similar to using Reboot or the Shutdown command but with more options as well. Here are some examples.
Sudo init 0 = Shutdown
Sudo init 1 = Single User Mode
Sudo init 3 = Multi User No GUI
Sudo init 5 = Multi User With GUI
Sudo init 6 = Reboot
Have Fun & Enjoy.
