Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I just ran into the damnedest idiosyncrasy with gnuplot (http://www.gnuplot.info/). I was doing my routine spending/budget plots when suddenly gnuplot bombed with a cryptic message. I spent all morning figuring out what was wrong. In the end, as usual, it was pilot error ...
I am plotting a data file with up to 12 blocks of data (counted as 0, 1, 2, ..., 11), where each block is separated by a blank record. The command
I have an 11-year-old computer with an AMD Athlon XP 2400+ (32 bit) processor and ASUSTeK Computer A7V8X motherboard. The machine has Ubuntu 12.04 installed.

Suddenly, Chromium would no longer run, or even start on this machine, though Chromium 36 is working OK on two other newer Ubuntu machines. When executed from the command...
A friend of mine sent me a Dell Optiplex 740, complete with box only and no hard drive, only 1 Gb RAM. I happened to have two sticks of RAM in my dead HP which fit the bill, and an old hard drive which never too a liking to Windows XP. Turns out I was running Ubuntu 10.04 on it, in 64-bit flavor. Well, that works for me. I turned the computer on and it ran. That's all I wanted. I upgraded to the latest LTS of Ubuntu.
I have two problems. One is that it boots up with sound muted. I...
A few days ago I had a heart-stopping moment on my main linux box running Ubuntu 12.04. I had just deleted two links from my desktop when suddenly I discovered that none of the remaining links on the desktop were working. Worse, clicking on any one of them them produced an error box saying the linked file no longer existed. I actually broke out in a sweat. All of these links are to files on a second internal hard disk where I keep my own data files, as opposed to the files for the OS and the various...
got me to worrying what I would do if my main boot disk failed. I keep my data files on a second hard disk, which I back up to an external drive on a weekly basis. I don't back up much of the boot disk.
Certainly something I should have is an alternate method of booting the machine. Although I know there are several...
