G'day Fabrizio,

Welcome to the monastery.

Here's a couple of points unrelated to your "pattern matching" query.

I see you've attempted to use lexical variables (with my) throughout your code — which is good. Had you used this line at the top of your code: 

use strict;

[download]

The 'vars' stricture of strict would have alerted you to the fact that you'd forgotten to do this for @hostname_short.

Had you also used this line at the top of your code: 

use warnings;

[download]

The 'syntax' category of warnings would have emitted a message that actually gave you a better way to write @hostname_short[0]: 

Scalar value @hostname_short[0] better written as $hostname_short[0]

[download]

Using both of these pragmata in all of your scripts is a very good idea.

As it turns out, you could have written both of these lines: 

@hostname_short = split(/\./,$fqdn,2);

my $hostname = "@hostname_short[0]";

[download]

as just this single line:

my $hostname = (split /\./, $fqdn, 2)[0];

[download]
