I have a perl script that I wrote the loops through a list of servers in a
file and I want to create a hash with the server name in it. I want each
server to have its own hash.

for example
$myserver = thor;
hash name
$server_$myserver_name{$some_key}
want to get this hash name
$server_thor_name{$some_key}

How do I get the $myserver name to be interpolated to thor in that line?
I tried this and it failed.
$server_${myserver}_name{$some_key}

You mean a the server name as part of the variable name? Well, maybe you
think that's what you want, but it is A Very Bad Idea (TM). See the FAQ "How
can I use a variable as a variable name?" and gazillions of previuos
discussions in CLPM for details.

I
want each server to have its own hash.

Just use a hash of (references to) hashes.

$server_$myserver_name{$some_key}

Why not
$servers{$myserver_name}{$some_key}

Sounds good. A master hash with server name as the top-level key.

I want each server to have its own hash.

With a hash of hashes, each server has its own hash. The server's hash
just doesn't have a name; it is a member of the master hash.

$server_$myserver_name{$some_key}

$servers{$myserver_name}{$some_key} = $value;


foreach my $server (sort keys %servers) {
print "Processing server $server\n";
foreach my $key (sort keys %{$servers{$server}}) {
print " $key = $servers{$server}{$key}\n";
}
}

P.S. The newsgroup comp.lang.perl is defunct. Use comp.lang.perl.misc instead.
