NAME

       hostname - show or set the system's host name
       dnsdomainname - show the system's domain name


SYNOPSIS

       hostname  [-d]  [--domain] [-F filename] [--file filename]
       [-f] [--fqdn] [-h] [--help] [--long] [-s]  [--short]  [-v]
       [--version] [name]
       dnsdomainname


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.
