RE: use Variable as a hashname?

[Timothy Johnson]

Here's one way to go about it.  It sounds to me like an array of hashes will
work just fine for you.

Let's say you have an array:

  my @routers = ();

You can do a 

  push @routers,"stimpy";

to add a scalar to the end, but you can also add an entire hash indirectly
by using hash references:

  #Example 1:
  push @routers,\%infohash;
  #Example 2:
  push @routers,{name => "stimpy", brand => "ren", model =>
"powdered_toast"}

In example 2, I created an anonymous hash and added it to the end, which has
the same effect as example 1 except that I didn't have to already have a
hash created.

The end result is that once I've created an array of hash references, I can
do this:

  foreach(@routers){
    print(sort keys %{$_});#dereference
    print "$_->{name}\n";  #access indirectly
  }

Check out "perldoc perllol" (list of lists) for more info.

It a little bit misunderstandable...

let´s say i got 100 hashes named after each of my routers.

a list auf my routeres is in @allmyrouters.

My hashes contains fileds: ip, interfaces, admin.

I want to access each hashes field admin in a loop.

How do i do that?
