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.

Is there any file utility in Linux to truncate from beginning of the file. I have a growing binary file and I need to delete part of it whenever it reaches pre-specified limit. I need to delete the old data. Please let me know how can I handle it.
It is work. I used tail with -c to solve my problem. Thank you so much.
I'd like to ask, let said I have few Mbytes data in the file.txt, the 'tail' still can work to redirect output to out.txt (up to how many bytes tail can support)?
