Oh what whall I say...
That "-> https://www.unix.com/shell-programmi...-new-post.html <-" was really costing my nerves!
Thanks here again to Made In Germany (MIG) for his 'echo wrappers' (and the additional help)!

Luckily at least ask seemed to work 'out of the box' for the pipe tweaks today. Smilie

Allthough the average load & output time was around 0.150 s (0.097-0.210), it recently became 'jumps' up to 0.300 or higher.
As a natural tweaker, I wanted to fix this, one breaks things along the way - which helped to make the load sequence more stable.

As I had prepared a subshell process if no $COLUMNS and no $LINES should be available,
to have them calculated and exported, but since my sytem has them at hand, well, I just assumed the code would work,
since there were subprocess and I had seen with set -x that the code indeed was executed in the shell.

Regardless, the exported variables were not to be found in the shell I sourced the file with the the sub process in from.
Something like this:
Code:
[sea/ .bin]$ cat testfile 
(
	declare -g my_test_a="a test"
	export my_test_b="an exported beer"
)
[sea/ .bin]$ . testfile 
[sea/ .bin]$ echo $my_test_a

[sea/ .bin]$ echo $my_test_b

Well, something like this, but with a looped sleep while grep checked the ps output for the $PPID as actual sub process.

That was quite, disencouraging.
This would have been so cool, real multi-tasking in console!
Guess I'm too much of a dreamer Smilie

Next will be alot of small utility functions, and to finalize the current core commands with 'help' functionality - before adding new core (usualy slitly bigger/ more complex command functions..

Inline::Wrapper::Module(3)				User Contributed Perl Documentation				Inline::Wrapper::Module(3)

NAME
Inline::Wrapper::Module - Internal object wrapper for individual Inline modules. SYNOPSIS
use Inline::Wrapper::Module; DESCRIPTION
Inline::Wrapper::Module is used internally by Inline::Wrapper, and should not be used directly. It will croak if you attempt to do so. It is a descendent class of Inline::Wrapper. METHODS
new() Takes the same arguments as "new()" in Inline::Wrapper, but also requires a module_name and lang_ext argument. Don't use this. It will croak if you try to use it directly. initialize() Initialize the object instance. DESTROY() Destructor to clean up the object instance, and wipe the private code module namespace created when binding the symbol list. INHERITANCE
As Inline::Wrapper::Module is an inherited class from Inline::Wrapper, all methods that apply to the base class also apply to objects of this class. However, note that this has the following effects, due to the semantics of the load()/run() steps: auto_reload settings vs. when method effects take place: auto_reload value: | FALSE TRUE --------------------+------------------------------------------ set_base_dir() | no effect after next reload / run() set_language() | no effect after next reload / run() add_language() | no effect after next reload / run() Please read through "load()" in Inline::Wrapper and "run()" in Inline::Wrapper for insight into why the implementation works like this. SEE ALSO
Inline::Wrapper The Inline documentation. The Inline-FAQ list. The examples/ directory of this module's distribution. AUTHOR
Please kindly read through this documentation and the examples/ thoroughly, before emailing me with questions. Your answer is likely in here. Also make sure that your issue is actually with the Inline::Wrapper modules, and not with Inline itself. Jason McManus (INFIDEL) -- "infidel AT cpan.org" LICENSE
Copyright (c) Jason McManus This module may be used, modified, and distributed under the same terms as Perl itself. Please see the license that came with your Perl distribution for details. perl v5.18.2 2010-03-10 Inline::Wrapper::Module(3)
