hi,
please i want a book or a site or a video tutorial about linux networking command line.

Hi there,
could you be abit more specific about what you are trying to achieve?
Is it generic information about setting up your NIC (network interface card) that you seek?
Perhaps need to configure your wifi?

Assuming you require basic linux networking how-to for your ethernet network card, the Linux Documentation project Networking How-tois always a good start, unless you are using Ubuntu and derivatives.

Then probably better head to Ubuntu's Network how to

To learn alot about networking in Linux from an administrator's perspective this pdf book by the linux documentation project is very comprehensive

what about advanced networking command line?

What 'distro'? (the network commands are different!)

This web-search string might help:
advanced linux intitle:network* command line
(replace the word 'linux' with the distribution of Linux that you use)
Adding intitle:advanced, located an interesting .pdf and more
(note that the three underlined blue things in the above line, are links to click on)

What I do next is:
pick out some of the commands which I am interested in,
then do a web-search with those keywords.

I hope this helps. Best wishes...

man ip
man ss
man netstat
man route

these would keep you busy for a month.

man -k {net,ip\ }
(yea, some 'false positives', but ...)
