use the %ENV hash
print $ENV{HOSTNAME};
for example
to see a full list of available enviroment settings do
foreach $key(sort keys %ENV) {
print "ENV $key => $ENV{$key}\n";
}

Subject: is there another way to do this?
Is there another way to get access to the environment variables... this
works, but it seems kind of kludgy..
my $machine = `echo \$HOSTNAME`;
Also, is there a way to detemine whether the script is being executed by
root?
I tired doing:
my $is_root = `echo \$UID`
but for some reason this doesn't work, but it works in a bash script...it
appears that $UID isn't available or something...
thanks!
