LINUX BASICS
Linux traditionally operates in text mode or in graphical mode. Since CPU power and RAM are
not the cost anymore these days, every Linux user can afford to work in graphical mode and will
usually do so. This does not mean that you don't have to know about text mode: we will work in
the text environment throughout this course, using a terminal window.
Linux encourages its users to acquire knowledge and to become independent. Inevitably, you
will have to read a lot of documentation to achieve that goal; that is why, as you will notice, we
refer to extra documentation for almost every command, tool and problem listed in this book.
The more docs you read, the easier it will become and the faster you will leaf through manuals.
Make reading documentation a habit as soon as possible. When you don't know the answer to a
problem, referring to the documentation should become a second nature.
Linux is an implementation of UNIX.
The Linux operating system is written in the C programming language.
"De gustibus et coloribus non disputandum est": there's a Linux for everyone.
Linux uses GNU tools, a set of freely available standard tools for handling the operating
system
I found few basic commands that can be used on LINUX Operating system.
