Welcome Ashraf! There is LOTS of help at the link you gave, so I'm confused by what you mean. Those are text articles, not video, but they give a lot of information about the basic knowledge of Linux tasks and usage, especially from the command line. Of course, you will probably begin in a graphical environment, but it is still very useful to know the underlying basics.
Almost all "introduction to Linux" learning sites will introduce you to the command line. Maybe you are confused because you are not running a Linux distro yet and you can't follow the command examples? The best way to learn Linux is to download it and burn it to a DVD or USB, then boot it up and use it. You can also install Linux into a "virtual machine" using VirtualBox (free) in Windows. Or if you have a spare computer, go all out and install Linux directly on it.
There are MANY different versions of Linux, but many are very easy for new users... some examples are Ubuntu, Linux Mint, and Linux Lite. Try some out, and if you don't like them, try some others! You can search on Google or YouTube to find lots of Linux training videos, but everything kind of starts "in the middle" somewhere, so you need to use it a bit to start to get an understanding. If you really want to start "at the beginning".... you're back to using the command line!
If you have more specific questions, please open up a new thread in one of the forums, like General Linux or Getting Started. Folks here are glad to help. Good luck!
Welcome to the forums.I wanna know is Linux OS or not?
Welcome to the forums.
No its not,
You have the Linux kernel [the operating system] you have then got a distribution built on top of it, [this is your desktop and applications] which together make what most people call an operating system
GNU-Linux is the full and proper title for the Linux kernel, but everyone just calls it Linux
Linux Foss built distributions do not contain non-free [manufacturer supplied drivers] whereas most general distributions do
GNU is an extensive collection of free software, which can be used as an operating system or can be used in parts with other operating systems. The use of the completed GNU tools led to the family of operating systems popularly known as Linux. Most of GNU is licensed under the GNU Project's own General Public
thanks guys for your full kind responses.

Not a prerequisite at all. Will be helpful on the command line to some extent but not needed. I recommend looking at this page it's helpful in learning Linux and choosing your first distro. Enjoy the Linux journey!I am starting my journey with Linux, do I also need knowledge of Unix as a prerequisite?
Thank you for sharing the link, that's really helpful.
