  24 .SH DESCRIPTION
  25 .B Hostname
  26 is the program that is used to either set the host name or display
  27 the current host or domain name of the system.  This name is used
  28 by many of the networking programs to identify the machine.
  29 .LP
  30 When called without any arguments, the program displays the current
  31 name as set by the
  32 .B hostname
  33 command. You can change the output format to display always the short
  34 or the long host name (FQDN). When called with arguments, the program will
  35 set the value of the host name to the value specified.  This usually is
  36 done only once, at system startup time, by the
  37 .I /etc/rc.d/rc.inet1
  38 configuration script.
  39 .LP
  40 Note, that only the super-user can change the host name.
  41 .LP
  42 If the program was called as
  43 .B dnsdomainname
  44 it will show the DNS domain name. You can't change the DNS domain name with
  45 .B dnsdomainname
  46 (see below).
  47 .SH OPTIONS
  48 .TP
  49 .I "\-d, \-\-domain"
  50 Display the name of the DNS domain. Don't use the command
  51 .B domainname
  52 to get the DNS domain name because it will show the NIS domain name and
  53 not the DNS domain name.
  54 .TP
  55 .I "\-F, \-\-file filename"
  56 Read the host name from the specified file. Comments (lines starting with
  57 a `#') are ignored.
  58 .TP
  59 .I "\-f, \-\-fqdn, \-\-long"
  60 Display the FQDN (Fully Qualified Domain Name). A FQDN consists of a
  61 short host name and the DNS domain name. Unless you are using bind or NIS
  62 for host lookups you can change the FQDN and the DNS domain name (which is
  63 part of the FQDN) in the \fI/etc/hosts\fR file.
  64 .TP
  65 .I "\-h, \-\-help"
  66 Print a usage message on standard output and exit successfully.
  67 .TP
  68 .I "\-s, \-\-short"
  69 Display the short host name.
  70 .TP
  71 .I "\-v, \-\-version"
  72 Print version information on standard output and exit successfully.
