hope to be useful

well I am not very good in Linux...i've just used it's GUI and that for a short while.....never tried to explore it.
I think these books might help me......but just wanted to know...do you have any good E-Books for the starters in Linux?

This is quite a collection of books just for a not very broad topic like this. If I ever switch to Linux (not likely I can't live without the games that I own for Windows only) I will be sure to check out one of these books.

well,I have some ebooks for starters , send PM

well, I'm gonna tell more books, but they're in network security section .
