env perl shell script

env perl shell script

You don’t need a script. A one liner easily does the trick.

perl -e 'printf("%25s --> %s\n", $_, $ENV{$_}) for keys %ENV'

All those variables are available to the scripts started from the a shell; depending on the actual user and process running the script. You probably have a built-‌in env command too if that’s all you need. Try man env.
