I think I found that "perlvar", and I saw that $^O, but I didn't think it would give me what I want. After thinking about it, I guess it would work in most cases, but not in my specific case.

I have a PC that has Cygwin on it (and Perl comes with the Cygwin), and I also have ActivePerl on it. I brought up a Cygwin window, and wrote a little script like this:

#!/usr/bin/perl
#!C:/Perl/bin/perl
print "^O\n";

When I run it like that I get: Cygwin

If switch the two comment lines (so #!C:/Perl... is the first line), I get: MSWin32

What I really want to know is that if I am the running the script from a Cygwin window, regardless of which of those two builds of Perl runs the script, it will tell me I am running in a Cygwin environment. If I run the script from an XP CMD window, I want it to tell me I am running in a windows environment.
