NOTICE: The virtual chapters are often under revision and can change throughout the semester. You should refresh your view of this page each time your read it.

BASIS

If you are new to this virtual textbook, you should read the Virtual Textbook Orientation page before continuing below.

USAGE

Chapter Labels
This virtual textbook is grouped into virtual chapters labeled A, B, C, etc. (to minimize confusion with online tutorial chapters labeled as 1, 2, and 3).
Abstract Pages
Each chapter has a separate abstract page that provides an introduction to the chapter content. These pages are accessible by selecting the "Chapter Abstract" link beneath the topic title for each chapter in the second column. Links on the abstract pages are optional and need be read only to provide clarity about the underlined terms if needed. After viewing the abstract page, return to this page to select the links to the other readings for the chapter.
Link Depth
With the exception of the abstracts, all of the links below will open their own browser windows. Students will be responsible only to read the pages directly linked to the Table of Contents, but not to follow their linked content (unless by choice). In the case where the home page of a website is referenced, students should simply browse the linked site to become familiar with the resources it offers them; but they will not be required to know specific content from that site. When you are through reading the linked item, just close the new window and resume from this page.

F Installation
Chapter Abstract
The following articles are intended for review and consideration, but you are not expected to actually try to perform all of the steps described in each one. Linux installation practices are specific to each individual distribution. Read these articles for information about the installation process in general. But do not try to perform them.
General discussions - applying to all distributions:
[Instructor's page about Installation Issues].
[Guide to disks and disk partitions in Linux]
[Boot Managers: Introducing GRUB and LILO].
The next item relates to the Ubuntu 16.04 LTS distribution of Linux because Mint 18.3 is based on that version and there is far more information posted on the Internet about Ubuntu than Mint. The basic concepts are the same and apply to most distributions of Linux, but the specifics can be distribution dependent.
First, browse (rather than detailed reading of all pages) the [Ubuntu 16.04 Installation Guide] to develop an understanding of the scope of knowledge involved in the installation of Linux. Give detailed attention to the section entitled [Section 3.6: Pre-Installation Hardware and Operating System Setup]
Next, read the variety of pages below about installing Linux based on different Linux access methods (as described on pages 7-9 from the first article/link in this virtual chapter):
Pages 8-20 of the PDF document [Official User's Guide - Linux Mint 18.3 - Cinnamon Edition]. You can quickly scroll to any page by dragging the scroll box. The page number should appear near it. Save a copy of this file locally or print it out for later reference.
[Guide To Install Linux Mint 17 & 16 in Dual Boot With Windows 7] or view the related [How to Dual Boot Windows 10 and Linux Mint].
Next, read the general instructions about [How to create a persisitent bootable USB installation of Linux using Linux Live USB Creator]
Then browse the resources linked to the instructor's web page about the [creation of "Live" versions of Linux on DVD's or USB memory sticks] (including the video tutorials) in preparation for the first class project.
After an initial installation, there are a variety of additional steps often recommended to complete an optimal working environment. Read one of these entitled "[Things To Do List After installing Linux Mint 17]".
Finally, read your instructor's page about Linux Fundamentals.
Read about (and optionally try performing) [Practice Exercise F]
G Introduction
to Linux
(not distribution
specific)
Chapter Abstract
Briefly review the Linux Fundamentals document from Chapter F
Then read the page about Linux Shell Basics
Then read about how shells interpret Special Characters and view the list of Linux Keystroke Shortcuts
Now read about basic things you should know about the Linux Command Line Interface (that also will be studied in more depth in later chapters):
[The 5-Minute Essential Shell Tutorial]
Download and read [Rute User's Tutorial - (A general introduction to) Basic Commands] (you can skip Table 4.1 and sections 4.10 and 4.11)
Read about (and optionally try performing) [Practice Exercise G]

and [Linux file access permissions reference], and [File security]
Read about (and optionally try performing) [Practice Exercise I]
J The Shell
Chapter Abstract
Review instructor's page about [Linux Shell Basics] from Chapter D following the links in the Shell Syntax section.
Read all 10 sections of [Learning the shell]. Some will serve as a review of previous reading; but it is a very clear summary of many concepts and may help to fill in some gaps.
Then revisit [Linux Metacharacters] and study [Regular Expressions and the grep Commands]
Next read about [An Introduction to Linux I/O Redirection] and [Processes and Environment Variables]
Finally, browse (lightly) and bookmark for future reference the following sites:
[Bash Reference Manual on the GNU.Org site]. It covers more than just the shell, but is the best and most straight-forward overall reference on Bash that I have found to date.
[Bash Reference Manual from FAQS.Org]. It is a more chapter oriented reference.
[Bash Commands - Quick Reference] - a great summary listing of most important bash commands.
Read about (and optionally try performing) [Practice Exercise J]
K Shell Programming
Chapter Abstract
Read [A quick guide to writing scripts using the bash shell] and [Positional Parameters in bash]
Then read the following definitive essay about the use of different types of quoting in Linux shell commands and how those commands are interpreted. Note that because the article discusses so many different characters used in quoting that it uses its own special symbols (» and «) as literal quotes for that discussion. Those symbols are not used in Linux for quoting. The artice is entitled [A Guide to Unix Shell Quoting].
To summarize and reinforce the topic of shell scripting, follow each link (one click deep) on the page [Writing shell scripts].
Read about (and optionally try performing) [Practice Exercise K]

P Networking and the Internet
Chapter Abstract
OPTIONAL: I have some [tutorial Internet web-handouts] that you might find useful for general background on Internet and its services that is not specifically related to Linux.
REQUIRED: Obtain a general understanding of networking by reading a few chapters from an early (but still pertinent) online text [Linux Network Administrator's Guide]:
[Chapter 1: Introduction to Networking]
[Chapter 2: Issues of TCP/IP Networking]
[Chapter 5: Configuring TCP/IP Networking] (Ignore details, but read for general concepts)
[Chapter 6: Name Service and Resolver Configuration] (Read up to the heading: The DNS Database)
[Chapter 12: Important Network Features] (Essential knowledge if you plan to run servers)
ALSO REQUIRED: The concepts and practices discussed above are fairly generic and not targeted to any specific Linux distribution. Most of those pages are fairly old and discuss foundational concepts related to the the Internet and to networking in general. The following reading is more specific to the Linux Mint 13-17 distributions that we have been working with as our primary model in this course. Because Mint 17 is so closely based on the Ubuntu 14.04 LTS distribution which is thoroughly documented, there is not a much documentation (tutorials and reference resources) for Mint as one might expect. However, the Ubuntu documentation is extensive and closely related. So read the following:
The [Ubuntu 14.04 LTS Networking Guide]
[Ubuntu 12.04 LTS Precise Pangolin: Networking tips and tricks]
Read about (and optionally try performing) [Practice Exercise P]

Read about (and optionally try performing) [Practice Exercise R]
S Security Systems
