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.

What is binary file in linux?
A binary file is usually an executable, but could also be an image--eg a jpeg. More generally, any file that cannot be decoded to text using ascii, utf-8, etc.
I assume your error will be the same if you just do "cat pruebased"
You added "-e" in you second example---why? (It means gets instructions from a script)
Note also that you can use the "-i_ switch to have sed edit the file "in place.
I always thought -e meant extended... it doesn't mean run a script file as such, just run the following as if it were a script i think, so the language of the regex is enhanced or summat... never actually written a full grep script before...
Your error seems to indicate that you use back-quotes (`) instead of single quotes (') or double quotes ("). The kind you used in your first post (’) is yet another (invalid) kind.
Apart from that, just a small note: the 'g' in your expression is useless as the /$/ pattern can appear only once per line (this means "end of line").
As for the extended regexps, this is done with the -r option in sed. -e is the same for grep.
