We really can't just "tell you about things". This is a help forum, so if you need specific help, please ask. Otherwise there is a HUGE volume of discussion from others already on here for you to search for. Thanks.

Here is a good starting point: Rute User's Guide

I think not one person on this planet knows everything from A-Z about Linux, especially because there are different distros which different approaches how to assemble a Linux system.
For a starter follow the RUTE guide linked by jkirchner. This will give you a good understanding how to administer a Linux system and work with it. If you want learn more about Linux' inner workings you should have a look at LFS, but to master that you need to be proficient on the command-line and in compiling software.

Part of learning the whole Linux is to:
1. Touch the Command-line (terminal).
2. Make a Linux Distribution for educational-purpose.
3. Read the man page.
4. Contribute to Linux.
5. Code in C.
6. Use a more advanced Linux Distribution, Ubuntu is for babies. Try, uh... Debian? etc...
7. Get a kernel from kernel.org and compile it by yourself.
8. Learn how to use git and use more free and open-source software to get the taste of it.
9. Know who's who.
10 *IF* you want to learn deeper, you might want to take a look below:

Here is how Ubuntu is created, it took these steps of mankind:
1. In 1970, Unix was created as an Operating System kernel by Bell Labs and Lucent Technologies and was coded in the C Programming language.

2. In 1991, Linux is later created as a free and open-source Operating system kernel based on UNIX, it is created by a loosely-knit team of hackers, Linus Torvalds started it first as a hobby.

3. In 1993, Debian is later created and it is based on the Linux Kernel Directly with the package manager called "apt" by Ian Murdock.

4. In 2004, Ubuntu is later created and it is based on Debian GNU/Linux also grouped in a "Debian-based Distribution". It is started by Mark Shuttleworth and Canonical.

Summary:
UNIX => Linux => Debian => Ubuntu => and so on...
1970, 1991, 1993, 2004, 2004-present

This is the longest post I have ever posted in the forums. I give free knowledge, I help people and I've got nothing to lose.

No problem---all you have to do is follow the following steps:

• Install Linux and use it.
• read
• try things
• ask specific questions when you get stuck
• repeat as required
• 
  
• and---for extra credit---get into "distro-hopping": Keep at least 4 different distros on your machine and rotate in a new one at least once a week.

+1 for Rute.
Almost every Linux hard copy book published in the last "few" years will spend 4 to 5 chapters going over the fundamentals of the Linux OS.

I suggest the Library or purchase a recent Linux-specific book.

Thank u for information

I would also suggest the Going Linux podcast. It's specifically oriented to new Linux users.

In addition to the podcast archives, they have a large store of articles and screencasts produced with new Linux users in mind.
