G'day yourself Ken,
I stole a fantastic Aussie plum when I married in Sydney one of your country-persons. That cmd code that choroba cited is a simple Perl script. I downloaded it to macOS and tested. It works as advertised, except it is not a native env. If you want to print the environment you must say:cmd env
Mine will emulate env and replace GNU env, because I run multiple Perl's in multiple locations in the file system, and the scripts must not be aware of this. Next I'll try it in debian, but looking at the code, I can't imagine it not working. I may still implement it in C, just for grins. It should work for you too. Best...
