Perl script to show the environment variables
The following Perl code returns the environment variables which are set as part of the interaction between the browser and the web server, in alphabetic order:
<![CDATA[#! /usr/bin/perl
#
# displays environment variables
#
print "Content-type: text/html\n\n";
print '<html><head><title>Environment variables</title></head>';
print '<body bgcolor="#ffffff">';
print '<pre>';
for $key (sort keys %ENV)
{
print "$key=$ENV{$key}\n";
}
print '</pre>';
print '</body></html>';
