When you want something done quickly, or want to
understand what??™s going on under the hood when you ask
Linux to do something, the shell is the place to go.
In this chapter, you will learn the basics of interacting with
openSUSE, from logging in to understanding the file
system to dealing with file permissions.
You??™ll pick out the best shell for your working style and
play with some text editors, too. By the end of the chapter,
you??™ll be able to handle the power of being the Root user
and know when and how to wield that power.
Read this chapter in particular if you are transitioning from a
proprietary operating system, even more so if that operating
system was Windows 98 or earlier, which had no conception
of logging in multiple users and dealing with security via file
permissions. Read this chapter whether you are the administrator
(Root user) of your system, have some administrative
privileges (via sudo), or are just an ordinary user in an office
with an IT staff. If you are more experienced using Unix or
another Linux distribution, you may still find some new
tricks, or just get a refresher on the basics.
