Diesen Befehl kann man in der Commend Line wie folgt ausühren, ohne es erst in einem Skript zu speichern:

tux@earth:~$ perl -e 'print $_." = ".$ENV{$_}."\n" foreach ( sort ( keys %ENV ) );'

Will man das Skript als CGI Skript und die Ausgabe in HTML haben, kann man folgendes verwenden:
#!/usr/bin/perl
# file: env.cgi
print "Content-Type: text/html\n\n";
print "<b>".$_."</b> = <i>".$ENV{$_}."</i><br/>\n" foreach ( sort ( keys %ENV ) );
