Working with the System
Whether you login using the GUI or a character console, the way you
interact with a Linux system is essentially the same. You must first be
able to identify yourself to the system by providing the appropriate
information. This information is your user name or login name and a
password. As we discuss in other sections, by default Linux will prompt you
for this information when the system is started. Once you have correctly
identified yourself, you are given access to the system.
What happens next will depend on whether you are using the
GUI or a character console.
For simplicities sake, we will first talk about interacting with a system from a
character console, which can also be referred to as a character terminal. One
important reason for this is that even if you are using a GUI, you still have
access to a character terminal window and the way you interact is
the same. Also, when you connect to a remote system (i.e. using something like
telnet) the way you interact is the same as well.
