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 have a file which is continuously receiving new data throughout the day. Currently I use the tail -f command to view the last line to be written to the file as it happens in realtime. However, the data that I am reading in the format of a long, non-delimited string that looks like this:
I wrote a script to parse the string and return only the info that i want in a readable form and it works fine. But I am simply using a sample string as the value of variable $x in the script to test it. In other words...
What I NEED is to have the last line of the file read into the script as the file is updated and set equal to the variable $x. And then of course overwritten each time a new line is written to the file so that the script will return to me the PARSED VERSION of the string to appear on my screen in realtime. Can this be done??
