You may ask "Why another version of the hostname command?". The answer is
simple. A lot of people misuse the domainname command to get the DNS domain
name. Since the domainname command should ONLY be used to set/show the NIS
domain name (formerly known as Yellow Pages) there was no easy way to get
the FQDN (Fully Qualified Domain Name) or the domainname from within a
shell script.

This hostname command offers you some additional features:

- show the FQDN (long host name)
- show the short host name
- show the DNS domain name
- read the host name from file

For further informations simply type "hostname --help" or read the manual
page.

If the program is called as dnsdomainname it will simply show the DNS domain
name.
