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..

NAME
Locale::Codes::Script - standard codes for script identification SYNOPSIS
use Locale::Codes::Script; $script = code2script('phnx'); # 'Phoenician' $code = script2code('Phoenician'); # 'Phnx' $code = script2code('Phoenician', LOCALE_CODE_NUMERIC); # 115 @codes = all_script_codes(); @scripts = all_script_names(); DESCRIPTION
The "Locale::Codes::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924 four-letter codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying scripts. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $script = code2script('phnx','alpha'); $script = code2script('phnx',LOCALE_SCRIPT_ALPHA); The codesets currently supported are: alpha, LOCALE_SCRIPT_ALPHA This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician. It also includes additions to this set included in the IANA language registry. The Zxxx, Zyyy, and Zzzz codes are not used. This is the default code set. num, LOCALE_SCRIPT_NUMERIC This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician. ROUTINES
