With Unix, 4th Edition: Visual QuickStart Guide, readers can start from the beginning to get a tour of the Unix operating system, or look up specific tasks to learn just what they need to know. This task-based, visual reference guide uses step-by-step instructions and plenty of screenshots, and includes three years worth of new material based on the latest Unix developments. This reference guide details all Unix commands and options along with tips that put those commands in context. Leading Unix authorities Deborah S. Ray and Eric J. Ray leverage their expertise as technical writers and working in the industry (Sun Microsystems) as they take readers step-by-step through the most common Unix commands and options.

Today I was poking around INTERNET to find out what is the quickest way to find out which shell is in you are. Did a reasonable search and found some better ways

$ env|grep SHELL

$echo $SHELL ( But most of the time we dont know whether this env variable exists or not )

$echo $0 (zero) [i found this is the simplest one]

Before doing this INTERNET search i did some manual page search and where i got why can't i colorfulise my man pages and got MOST package

this is very simple in debain based linux like ubuntu

$sudo apt-get install most

and Then

$export MANPAGER="/usr/bin/most"

After the above two steps i did
$ man man -- awsome i can see all my colors

you can export MANPGER variable permanantly by adding export MANPAGER="/usr/bin/most" to /etc/bash.bashrc file.

If you dont have root access you can edit your ~/.bashrc file and export it.

After exporting MANPGER through any one of the above methods dont forget to source your profile scripts

#soruce /etc/profile (If you edit /etc/bash.bashrc)

Or

$ source ~/.bashrc (If you edit /home//.bashrc)

I love to do #man source :)

Note: I have tested this in ubuntu. If you are using Redhat/Fedora/CentOs use yum to get MOST package.

Linux now offers an exceptionally robust environment for driver development: with today’s kernels, what once required years of development time can be accomplished in days. In this practical, example-driven book, one of the world’s most experienced Linux driver developers systematically demonstrates how to develop reliable Linux drivers for virtually any device. Essential Linux Device Drivers is for any programmer with a working knowledge of operating systems and C, including programmers who have never written drivers before. Sreekrishnan Venkateswaran focuses on the essentials, bringing together all the concepts and techniques you need, while avoiding topics that only matter in highly specialized situations. Venkateswaran begins by reviewing the Linux 2.6 kernel capabilities that are most relevant to driver developers. He introduces simple device classes; then turns to serial buses such as I2C and SPI; external buses such as PCMCIA, PCI, and USB; video, audio, block, network, and wireless device drivers; user-space drivers; and drivers for embedded Linux–one of today’s fastest growing areas of Linux development. For each, Venkateswaran explains the technology, inspects relevant kernel source files, and walks through developing a complete example.

• Addresses drivers discussed in no other book, including drivers for I2C, video, sound, PCMCIA, and different types of flash memory

• Demystifies essential kernel services and facilities, including kernel threads and helper interfaces

• Teaches polling, asynchronous notification, and I/O control

• Introduces the Inter-Integrated Circuit Protocol for embedded Linux drivers

• Covers multimedia device drivers using the Linux-Video subsystem and Linux-Audio framework

• Shows how Linux implements support for wireless technologies such as Bluetooth, Infrared, WiFi, and cellular networking

• Describes the entire driver development lifecycle, through debugging and maintenance

• Includes reference appendixes covering Linux assembly, BIOS calls, and Seq files

RedCar is a TextMate like editor for Linux which supports almost all scripting and programming languages. It is designed to be compatible with Textmate bundles (a work in progress) and is written almost entirely in Ruby - with some Vala thrown in for speed. Redcar is still in its infancy so please be gentle.

As the ultimate resource on the basics of the Linux desktops, servers, and programming tools, this book is written by the ultimate author on all things Linux. This transition resource is ideal if you are making the move from Windows or Macintosh to using Linux as your desktop system, and explains the Linux technology, offers detailed installation instructions, and includes step-by-step descriptions of key desktop and server components. You’ll relish the in-depth descriptions that will help you choose the best Linux distribution to suit your needs.

This Book covers Ubuntu, Fedora, OpenSuSe, Debain and other Top 13 Linux Distributions.

The everyday Linux user can easily get overwhelmed by the complexity of the new software that exists when creating an Ubuntu system. This book covers the basics of creating a new system from scratch and explains what software is installed. You’ll take a tour of installing the Ubuntu Linux distribution system in most environments, including nontraditional situations such as dual-boot and text-based installations. Plus, clear explanations of each of the installed applications show you how to get the most out of each application, rather than simply using them as they exist.

Ext4, the next generation of Linux's Ext3 filesystem, is now available in the latest Ubuntu 9.04 installer images. Ext4 was officially declared stable in version 2.6.28 of the Linux kernel, which was released last month.

Ext4 is designed to provide better performance and increase reliability. It also increases the maximum filesystem size to one exabyte and reduces the amount of time that is required to perform a fsck operation.

Linux hardware site Phoronix has released benchmarks based on extensive Ext4 performance testing that was conducted with a solid-state drive. The most impressive results can be seen in the IOzone test, which measures write performance for a large file. In this test, Ext4 annihilated the competition and significantly outperformed XFS, JFS, ReiserFS, and Ext3. The new filesystem also outpaced its peers in the Intel IOMeter File Server Access Pattern Test.
