Hi RudiC,
You may indeed object. But, you need a very recent version of bash to get that shopt option. On the latest release of macOS, the bash installed is version 3.2.57 which produces the following when trying to set that option:
Code:
bash-3.2$ shopt -s lastpipe
bash: shopt: lastpipe: invalid shell option name
bash-3.2$

and a man bash | grep lastpipe produces no output.

Yes - I should have mentioned my bash version: 4.4.19(1)-release
