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.

bash-3.1$ cut -c 3-10 test
whichever characters you need, it looks like your example is wrong.
I was about to put a note about it. The example is moved automatically leftwards when I submitted it, but all you guys gave me the answer. Thanks again. BTW how do I thank each of you using the option by this forum? I tried and still it showed I thanked nobody.
In terms of execution speeds/memory sizes:
cut > sed > awk
Why did you pick the slowest of the tools?
Sorry for not responding sooner. I picked the slowest one because it is in awk. I started my script in awk and I prefer not to mix other commands unless necessary. The speed is not noticeable though because I have only about 200-300 lines of input.
