Looking for sites and books on learning Linux
First of all, I want to say that I am not new to computers, so I am not looking for something that will assume you barely know how to turn a system on or use a mouse, or are unfamiliar with standard concepts such as copy and paste and so forth.
I've been using Windows and DOS for over a decade now, so mostly my experiences are limited to the Windows GUI and the DOS CLI, as well as performed dozens of hardware upgrades and system builds.
I have installed small Xubuntu partitions on several of my systems, as an emergency/backup os, my laptop is the main system I am trying to learn Linux on, I triple boot windows and two distros of Linux on it.
My main laptop has Ubuntu using GNOME and OpenSUSE using KDE installed on it. So far I have mostly been using GUI tools, not a great way to start off since Linux is so heavily cli based, and found this to be the hardest os to attempt to self-learn from all the ones I have tried, including other cli based operating systems ( ok ok, on second thought, AS/400 systems were worse....). On top of this I only have academic programming knowledge, I can't actually program anything beyond Hello World, not good since Linux is heavily based on open source as well, haven't had much luck attempting to compile the odd program every now and then that isn't in the repositories either.
Clearly, I am not going to be able to learn how to use this operating system from just attempting to use it, which is why I am asking what sites, or preferably, books you would personally recommend to learn how to use Linux, and eventually even how to troubleshoot and administer it.
