NAME

String::ShortHostname - extracts the first field from an FQDN

VERSION

version 1.000

SYNOPSIS

This module will take a fully qualified domain name and return the first field which is normally the short hostname (mostly equivalent to hostname -s on Linux).

    use String::ShortHostname;
    my $fqdn = 'testhost.example.com';
    my $hostname = short_hostname( $fqdn );
    print $hostname; 
    # prints 'testhost'

If an IPv4 address is passed to it, it will be returned verbatim. Otherwise the logic is simply to return everything before the first ..

Alternatively, it can be used in an OO way, but without much benefit:

    use String::ShortHostname;
    my $fqdn = 'testhost.example.com';
    my $short = String::ShortHostname->new( $fqdn );
    my $hostname = $short->hostname;
    print $hostname; 
    # prints 'testhost'
