Login and Shutdown
After rebooting your PC, you'll be able to log in to a Linux session. If X11 wasn't configured during the installation, you'll log in at a text-based login prompt. If you configured X and enabled a graphical login, the screen will clear after Red Hat Linux boots, and you'll be presented with a graphical login screen.
To log in, type root and press Enter. Next, type in your root password and press Enter to start using Linux as the system administrator. If you use a graphical login, you can use the shutdown or reboot menus in the dialog box to shut down or reboot your system. To shut down your system from the command line of a text-based session, use the shutdown command with its -h or halt option and the keyword now or the numeral 0 like this:
# shutdown -h now
You can also use
# shutdown -h 0
You can also use the shutdown command halt to reboot your computer like this:
# shutdown -r now
Or you can use
# shutdown -r 0
For new users, installing Red Hat Linux is just the beginning of a new and highly rewarding journey on the path to learning Linux. For Red Hat Linux system administrators, the task ahead is to fine-tune the installation and to customize the server or user environment.
