How to test if in a specfic UE(unified enviroment)?

[Ashcraft]

I test to see if I'm in a UE with this
if( ! exists $ENV{‘WARD’})
Is there a way to test more specfically? So sometimes to run certain programs you have to be just not in a UE but like one that has only permissions for a certain group like Integration or Validation?

Can you clarify how this relates to Perl?

I'm writing my script in Perl.

What do you mean by "unified enviroment"?
