HOSTNAME(1)

NAME
hostname - set or print name of current host system

SYNOPSIS
hostname [-fs] [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:

-f  Include domain information in the printed name. This is the default behavior.

-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 supplied.
