In the literal, legal sense, UNIX means you had your operating system tested and certified as UNIX-compliant. Apple did this, and Linux hasn't (and perhaps can't, except for a tiny subset of configurations and features.)

In the same sense, Windows NT was partly compliant back in the day. They hastily added enough bolt-on modules and compatibility software it was compliant for a few narrow cases.

Sys::Hostname::Long(3)					User Contributed Perl Documentation				    Sys::Hostname::Long(3)

NAME
Sys::Hostname::Long - Try every conceivable way to get full hostname SYNOPSIS
use Sys::Hostname::Long; $host_long = hostname_long; DESCRIPTION
How to get the host full name in perl on multiple operating systems (mac, windows, unix* etc) DISCUSSION
This is the SECOND release of this code. It has an improved set of tests and improved interfaces - but it is still often failing to get a full host name. This of course is the reason I wrote the module, it is difficult to get full host names accurately on each system. On some systems (eg: Linux) it is dependent on the order of the entries in /etc/hosts. To make it easier to test I have testall.pl to generate an output list of all methods. Thus even if the logic is incorrect, it may be possible to get the full name. Attempt via many methods to get the systems full name. The Sys::Hostname class is the best and standard way to get the system hostname. However it is missing the long hostname. Special thanks to David Sundstrom and Greg Bacon for the original Sys::Hostname SUPPORT

Not Tested Solaris SUN Solaris 7? OK (now) Irix SGI Irix 5?

Unix Most unix systems have trouble working out the fully quallified domain name as it to be configured somewhere in the system correctly. For example in most linux systems (debian, ?) the fully qualified name should be the first entry next to the ip number in /etc/hosts 192.168.0.1 fred.somwhere.special fred If it is the other way around, it will fail.
