I create a hash from a file using format similar to /etc/group:

process:text:action:email

ie:

syslogd:syslogd daemon::user@host.com

I create hash:

@fields = split /:/;
$process = shift @fields;
$hash{$process}{'TEXT'} = shift @fields;
$hash{$process}{'ACTION'} = shift @fields;
$hash{$process}{'EMAIL'} = shift @fields;

And I can do:

print "$hash{'syslogd'}{'EMAIL'}\n"; and get "user@host.com"

But how do I reference not the key ($process) but the sub-key (for lack of better term) in the above hash in a foreach?

foreach my $processKey (sort keys %hash)
{
   print "$_";
   foreach my $hashKey (sort keys $hash{$processKey})
   {
      print ":$daemontable{$processKey}{$hashKey}\n";
   }
}

This ofcourse doesn't work. I don't understand how to get at the "EMAIL", "ACTION", "TEXT" fields of a hash other then specifying them manually (which defeats the purpose)

The idea is that I don't need to manually add code everytime I add a new sub-key into the foreach loop.

I apologize if my terminology is off.
