The standard Perl Sys::Hostname gives you the function hostname, but
that basically gives you `uname -n' (FQDN on standard Red Hat install,
but unqualified hostname on every other system I've used). The
Net::Domain, from the libnet set of perl modules
CPAN/authors/id/GBARR/libnet-1.0606.tar.gz
gives you three functions: hostname, hostfqdn, hostdomain which try hard
to return unqualified hostname, fully qualified domain name and domain
respectively. I've tested in on Red Hat Linux 5.2, Silicon Graphics
IRIX 6.2 and Digital Unix 4.0D, all work as expected.
