HOSTNAME(1) DragonFly General Commands Manual 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.
