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 managed to mangle my system trying to add a second disc to my logical volumes. Senior Member here at LQ "WhatsHisName" gave me tremendous help to correct my many errors. However, I had screwed up even worse than I was willing to admit in that thread. I had gone in and edited my fstab in my vain attempts to correct the error myself - with dread results. Working through WhatsHisName's instructions I was able to get to a point where I could remove my needless additions to fstab. But the only way to do it was to use vi.
Now I know this will probably spark fierce debate, but really - there are only people that love vi or hate it (excluding those who don't know what I'm talking about). I am one of the later. Sorry, let me apologize up front - but I really really hate vi. Booting in rescue mode I noticed a file called "joe". WTF - I typed joe. Low and behold, up comes the vi of my dreams. One I can actually use!
After recovering my system, thanks to the wise counsel of WhatHisName, I searched high and low for my beloved joe. Nowhere to be found. Who is this joe and how can I get him back?
If you look in your linuxquestions.org profile, you should be able to find a list of all of the threads that you have participated in. From there, you should be able to recover joe's username. Hope that this helps.
hehe when he says "whatshisname" he means an actual username called that that helped him out.
i think he's after the program called Joe which is an editor simpler than VI.
In answer to the problem, theres a few possible reasons.
1) when you were in recovery mode you were logged in as root, whose path includes wherever Joe is
2) You were runnning from root on the CD not your system root (did you chroot /mnt/sysimage?)
3) you uninstalled it by accident.
*login as root and try the command joe again
*slocate joe (may tell you to run updatedb as root first)
*yum install joe (will either install it or tell you it's installed
