NAME
     hostname — set or print name of current host system

SYNOPSIS
     hostname [-s] [name-of-host | -r ip-address | -i interface [-6 | -4]]

DESCRIPTION
     The hostname utility prints the name of the current host.	The super-user
     can set the hostname by supplying an argument; this is usually done at
     boot time by setting the hostname variable in /etc/rc.conf.

     Options:

     -s	   Trim off any domain information from the printed name.

     -r	   Retrieve hostname via ip lookup.  The hostname is set to the first
	   (official) name returned for the supplied ip address.  Can be an
	   IPv6 or IPv4 address.

     -i	   Retrieve hostname via supplied interface name.

     -6	   Used in conjunction with -i to select the 1st IPv6 address on the
	   interface.

     -4	   Used in conjunction with -i to select the 1st IPv4 address on the
	   interface.  This is the default and assumed if -6 or -4 is not sup‐
	   plied.
