Please refer to the following link for a very basic explanation of bash variables.

http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-5.html

It's a relatively short document, and I recommend reading the whole thing. I also recommend reading the Advanced Bash Scripting guide, here:

You might also like to look at cut &/or awk.
