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.

Ok, thanks, it works now.
But return only takes numeric values apparently.
The value of the special parameter '?' shall be set to n, an unsigned decimal integer, or to the exit status of the last command executed if n is not specified. If the value of n is
greater than 255, the results are undefined. When return is executed in a trap action, the last command is considered to be the command that executed immediately preceding the trap
I should read the man more often.
[I even started reading the source code of true and false. 82 lines for true.c and 2 for false.c ^^.]
So there is no way to access the return value directly as in C?:
