That script fails to properly escape environment variables that contain HTML-sensitive characters, a common mistake of course. I'd stick with something this simple: 
#!/bin/sh
echo content-type: text/plain
echo
printenv

Yeah, and if you're not on a system with a shell or printenv, you can do it in Perl if you insist: 
#!/usr/bin/perl
print "Content-type: text/plain\n\n";
print "$_\t$ENV{$_}\n" for sort keys %ENV;

See how much simpler that is? And no problems if there's HTML involved.

Sometimes, HTML is overkill.
