The commands in pipelines have to be executed in subshells, apart
from  the  last command, which technically can be executed in the
current shell. Most shells do it this way, the bash does not.  It
runs the last command in a subshell as well.

I searched for a shortcut where there is none.  Either  one  goes
non-portable or one has to make use of temporary files or such.

The discussion exploded quickly after a zealot appeared, who told
how stuff has to be done, without providing a rationale grounding
for his statements.

I took this from the topic:

1) Several (imperfect) ways to solve my problem

2) The open question why the bash  behaves  differently  (without
technical necessity and with greater complexity)

3) More alertness for such explosive topics and the goal to  stay
calm even when others write in a destructive manner
