hi,
pls help me with linux for beginners guide

What help are you looking for? Could you please provide more specifics?

Which distribution or "distro" are you using? All of the good ones have help/wiki pages, for example:

https://help.ubuntu.com/
https://fedoraproject.org/en/get-help

etc.

What things do you want to know? All the best distros have a manual or a wiki which will get you off to a good start, like
http://community.linuxmint.com/tutorial/view/20
http://www.fuduntu.org/wiki/index.php/Main_Page
http://www.mepis.org/manual
http://www.salixos.org/wiki/index.ph..._Startup_Guide

When you've installed, the user interfaces have their guides, accessible with F1, and their websites
http://www.xfce.org/
http://mate-desktop.org/
http://kde.org/

Programs have their help and websites.

The mysterious command line (great when you get to know it) is best explained by the old but good RUTE:

Above all, try things out! So long as you always make a backup of a file before altering it, you can recover from any mistakes. Unlike James Bond, you can't make your computer explode from the keyboard!

My own favorite when I was first learning Linux:

http://tille.garrels.be/training/tldp/. Machtelt Garrels's Intro to Linux.

I'd like to recommend the Arch Linux wiki https://wiki.archlinux.org/. I find it to be useful. Other than that I think that installing and using a bunch of different distros and not being afraid to break something is the best way for a beginner to learn linux.
