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.

Grep allows the unquoted string, but it is limited by what BASH will let pass.
Use quotes when you want to be exact, or anytime you are unsure.
You will still have problems with some characters that are specially interpreted.
Then you will have to backslash characters to get the search you want.
>> grep " 17:00" *
- without the quotes, the space would not be in the search string. This applies to arbitrary strings.
>> grep "The quick brown fox went up the twisty road" *
>> grep " fred[" *
- will not work, will get an error message
>> grep " fred\[" *
- backslashed to get the square bracket into the search string as it is.
>> grep " 17:00" * | grep " something else"
- to apply more than one grep test to a line
>> grep " 1:00" *
and look into rgrep and egrep.
