Any other good reading beyond your answers to learn how to properly code in Bash?
A tutorial book?
Some classical script examples in a book, a website, or maybe a reference developer on github or Code Snippets - Snipplr Social Snippet Repository or something else?
Some other forums maybe too?
If some answers or advice cannot be given publicly, please drop me a quick message.
Many many thanks for your help!
Kindest regards,

If you find my suggestions informative, you can search this site for my 7,000+ posts.

I'm old fashioned and taught myself how to use UNIX utilities and the C programming language by reading a PWB UNIX manual from cover to cover three or four times making sample scripts and programs that used utility options I had never noticed before, used C functions I'd never heard of before, etc., until I figured out how they worked (or found someone with more experience than me to explain it to me). When I found bugs in the man pages, I filed bug reports and suggested better wording and examples. Eventually they started asking me to review man page changes new man pages for new functions and utilities. (But, of course, that was well before there were on-line tutorials or a long list of good books. And, hard copy manuals are harder to find now.)

To learn how to use bash on your system, I would still strongly suggest that you read the bash man page on your system very carefully. At first, some parts of it may look cryptic and incomprehensible, but with a little practice reading other man pages, you'll find a wealth of information there.

To write code that will work on a wide variety of BSD, Linux, and UNIX systems, look at the man pages on this site and select the POSIX 1003.1 man page set. If you restrict yourself to the utilities and utility options described there, most of the code you write will work on most systems.

undocumented

UNDOCUMENTED(7) 					     Linux Programmer's Manual						   UNDOCUMENTED(7)

NAME

       undocumented - No manpage for this program, utility or function.

DESCRIPTION

       This  program,  utility	or function does not have a useful manpage.  Before opening a bug to report this, please check with the Debian Bug
       Tracking System (BTS) at <http://bugs.debian.org/> if a bug has already been reported.  If not, you can submit a wishlist bug if you want.

       If you are a competent and accurate writer and are willing to spend the time reading the source code and writing good manpages please write
       a  better  man page than this one.  Please contact the package maintainer and copy man-pages@qa.debian.org in order to avoid several people
       working on the same manpage.

       Even if you are not an accurate writer, your input may be helpful.  Writing manual pages is quite easy, the format is described in  man(7).
       The most important and time-consuming task is to collect the information to be put in the new manpage.

DIAGNOSTICS

       It  is  possible  that  the man page for the command you specified is installed and that your manual page index caches are out of sync. You
       should try running mandb(8).

       Try the following options if you want more information:

       foo --help, foo -h, foo -?

       info foo

       whatis foo, apropos foo

       dpkg --listfiles foo, dpkg --search foo

       locate '*foo*'

       find / -name '*foo*'

       Additionally, check the directories /usr/share/doc/foo, /usr/lib/foo.

       The documentation might be in a package starting with the same name as the package the software belongs to, but ending with -doc or -docs.

       If you still didn't find the information you are looking for you might consider posting a call for help to debian-user@lists.debian.org.
