Use UNIX

UNIX is a user-friendly system. It is only sometimes that there is something unique about the choice of friends.

Perhaps this phrase particularly characterizes UNIX. It's actually easy to use and not that difficult to learn. But you have to do a little more than click randomly on pictures with the mouse. You don't learn UNIX through trial and error, but rather by using the aids offered to understand what is happening.

The first chapter should show how to move on the console under UNIX and convey the simplest basic commands. Some technical terms are explained in the glossary in the appendix.

In times of graphical user interfaces you don't have to work with the text-based user interface, not even under UNIX. But under UNIX in particular, it would be a loss not to know them. The command line opens up possibilities for combining the very powerful UNIX tools, which cannot be implemented in this form on graphical interfaces. The use of the command line, which most UNIX users still use in addition to the graphical user interface, does not express that the graphical user interfaces are unusable, but that the command line is extremely powerful.

But a text screen has other advantages as well. It is important for the administrator to be able to carry out remote maintenance even over the slowest telephone line.
