DESCRIPTION
Hostname is the program that is used to either set the
host name or display the current host or domain name of
the system. This name is used by many of the networking
programs to identify the machine.
When called without any arguments, the program displays
the current name as set by the hostname command. You can
change the output format to display always the short or
the long host name (FQDN). When called with arguments, the
program will set the value of the host name to the value
specified. This usually is done only once, at system
startup time, by the /etc/rc.d/rc.inet1 configuration
script.
Note, that only the super-user can change the host name.
If the program was called as dnsdomainname it will show
the DNS domain name. You can't change the DNS domain name
with dnsdomainname (see below).
OPTIONS
-d, --domain
Display the name of the DNS domain. Don't use the
command domainname to get the DNS domain name
because it will show the NIS domain name and not
the DNS domain name.
-F, --file filename
Read the host name from the specified file. Com-
ments (lines starting with a `#') are ignored.
-f, --fqdn, --long
Display the FQDN (Fully Qualified Domain Name). A
FQDN consists of a short host name and the DNS
domain name. Unless you are using bind or NIS for
host lookups you can change the FQDN and the DNS
domain name (which is part of the FQDN) in the
/etc/hosts file.
-h, --help
Print a usage message on standard output and exit
successfully.
-s, --short
Display the short host name.
-v, --version
Print version information on standard output and
exit successfully.
