Would you care if waiting on such identifications for background pr

Bash is very powerful for its ability to use all kinds of commands and pipe
information through them. But there is a single thing that is impossible to
achieve except using files on the hard drive or on /tmp. We need a new
declare -g (global) where a variable would have its contents changed by
subs

Yes, superglobal is great.
Example, from the manual:

Shared memory allows one or more processes to communicate via memory that

Is it doable?
Of course it's doable; all that takes is requirements, definition, and
implementation. The
