Previous Section: Logging In and Out
During your login process, a shell is started for you (the POSDI shell in our case). The shell is responsible for issuing the prompt and interpreting the commands that you enter. We will be discussing various commands for the remainder of this module that allow you to access the online reference manual, find out about users who are logged in to your system, and communicate with other users on your system.
As you can see from the slide, the shell has many other functions that supplement command interpretation.
