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.

Typing
echo $PATH
Will show you what your full current path is. Then, you can retype the whole thing without the parts you don't want, like this;
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/bin/X11
If you want to get fancy and automatic, you can use the sed program to remove the last entry automagically.
export PATH=`echo $PATH | sed 's/:[^:]*$//'`
Just copy and paste that to a terminal.
Remember, everything you export is forgotten when you log out anyway, unless you put the command in your ~/.bashrc file.
