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.

This is just an example, but if i were to use the 2nd option to copy say 30-40 specific files/types of files would that be lighter on the system, then the option with 1 variables, or does it really matter. typically this would be run ONCE on a system to transfer data from old computer to new.
The variable expansion is only performed once on the call to copy, it doesn't matter how many files are actually copied. If you're only calling the copy 30-40 times, then you're only doing the variable expansion 30-40 times, and it will have no effect on the speed of the process. If this was inside a high speed loop that was iterating thousands/millions of times in a matter of seconds, then it might start to make a difference, but the copy itself will use FAR more time than the variable expansion in this case, so it'll make no practical difference.
