Subtitles of the Movie

For the final movie in this section we'll discuss the different ways you can shut down and reboot your system. Of course you can log out of Gnome or KDE as a regular user. And when you do with the appropriate switch you're prompted to shut down or reboot the system. Nothing special there. But in this tutorial we discuss the actual commands which are straight forward. You can invoke the reboot, shut down or halt commands directly or you can invoke the appropriate run level. As discussed in other movies 0 shuts down 6 reboots. Specifically if you want to shut down your system now you can run a command like shut down each now. If there are others connected to your system you can specify a time delay. For example, the shut down command at the etc inittab configuration file shuts down the system two minutes after receiving a power failure signal. But you don't have to wait for a power failure signal. You can use this command directly which waits two minutes and immediately sends the quoted messages to users that are logged onto your system. With Red Hat Enterprise Linux the halt command by itself is sufficient even regular users can use the halt command unless you delete it from the users slash bin directory. Which may be a good idea if you don't want unauthorized shut downs of your system. The regular shutdown and halt commands are also available from administrative users in the espin directory. Two other options to halt your system are power off and init 0 which is actually equivalent to telenet 0, well not exactly equivalent but close enough for our purposes. Either of these commands require administrative privileges. The reboot commands which keeps your system powered up and reboots are just as simple. You can run the reboot command by itself, the shutdown-R now command works just like the reboot command. Alternatively you can move your system to run level 6 with a command like init 6 or telenet 6. That's it for this section, thank you and on to the next video.
