OK sorry if confusing.
Testing $> itself should be false when sudo - yes.
Goal is to allow sudo when needed by files permissions and user otherwise,
Info I had said that when running administrator these should be called:
use strict;
use warnings FATAL=>"all";
if($>)
{
exec { "/path-to-wrapper-program" }
( "/path-to-wrapper-program",$0,@ARGV);
}
My confusion was that Id assumed the exec call was for sudo but now seems pointless, as application runs fine without.
