Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Can someone tell me something about learning from the "Info bash" on the console . I just managed to move around and i would like to know about it's importance for someone that don't have a clue on linux like myself. I mean would you recomend it , and , if you please, where does it really stand on linux learning.It looks like those who did where dead serious about it .
I actually don't have a specific topic , i want to know more about linux in general . It seems that most of sites and books material i went through are assuming that you have the skills to understand wich i don't .
Are shells important to the new linuxers?
what are their utility?
This is a fairly decent analogy. BASH is the "equivelant" of DOS prompt or DOS command line. I don't know how much time you've spent there, but DOS was the actual operating system years gone by. Now windows rides on top and in NT it uses it's own platform. The similarities are in the facts that it allows you to move around and perform your operating system functions. To list the directory contents, instead of DIR (which works though) it's 'ls'. Bash and other "shells" all perform system functions and that's pretty much it. X as the old windows did, "rides" on top of linux as a server. The shells are definately important, without them you don't have Linux. As the 'kernel' is the core of a Linux system, the shells are the access to that core. That's how i'd explain it. Someone may be able to give you a better explaination...Hope it helped some either way.
Originally posted by jamaso thanks . I would like to ask you if there's any real damage than can happen if you mess with the console to learn about the commands, syntaxe , and so on ?
Unless you are root (which you shouldn't be for experimenting), or important bits of the system are world writable (which they shouldn't be), the the worst that can happen is that you blow away your data files and user configuration files.
PS: Is there a way to erase all the input you typed on the console before you close the session?
Are there commands that shouldn't be messed with "unless you know what you're doing" ?
Not really, as I said above your system should be secure enough that you wouldn't be able to run any commands like that, or if you could they wouldn't be able to do any damage.
