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.
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:
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
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..
this is the output i am getting here..

Hi,
I am trying to capture runtime stats of a shell script (c shell). Are there system variables to call? Or should I create a date variable at the start of the script and at the end of the script? I am trying to capture the time if the script stops or ends with error.
Please help.

alzabo::runtime::uniquerowcache
Alzabo::Runtime::UniqueRowCache(3pm) User Contributed Perl Documentation Alzabo::Runtime::UniqueRowCache(3pm)NAME
Alzabo::Runtime::UniqueRowCache - Implements a row cache for Alzabo
SYNOPSIS
use Alzabo::Runtime::UniqueRowCache;
Alzabo::Runtime::UniqueRowCache->clear();
DESCRIPTION
This is a very simple caching mechanism for "Alzabo::Runtime::Row" objects that tries to ensure that for there is never more than one row
object in memory for a given database row.
To use it, simply load it.
It can be foiled through the use of "Storable" or other "deep magic" cloning code, like in the "Clone" module.
The cache is a simple hash kept in memory. If you use this module, you are responsible for clearing the cache as needed. The only time it
is cleared automatically is when a table update or delete is performed, in which case all cached rows for that table are cleared.
In a persistent environment like mod_perl, you should clear the cache on a regular basis in order to prevent the cache from getting out of
sync with the database. A good way to do this is to clear it at the start of every request.
METHODS
All methods provided are class methods.
* clear
This clears the entire cache
* clear_table( $table_object )
Given a table object, this method clears all the cached rows from that table.
* row_in_cache( $table_name, $row_id )
Given a table name and a row id, as returned by the "Alzabo::Runtime::Row->id_as_string" method, this method returns the matching row
from the cache, if it exists. Otherwise it returns undef.
* delete_from_cache( $table_name, $row_id )
Given a table name and a row id, as returned by the "Alzabo::Runtime::Row->id_as_string" method, this method returns the matching row
from the cache.
* write_to_cache( $row_object )
Given a row object, this method stores it in the cache.
AVOIDING THE CACHE
If you want to not cache a row, then you can pass the "no_cache" parameter to any table or schema method that creates a new row object or a
cursor, such as "Alzabo::Runtime::Table->insert()", "Alzabo::Runtime::Table->rows_where()".
