HOSTNAME(1)

NAME
hostname - set or print name of current host system

SYNOPSIS
hostname [-f] [-s | -d] [name-of-host]

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 in the initialization script /etc/rc.d/hostname, normally run at boot time. This script uses 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.

-d  Only print domain information.

EXAMPLES
Set the host name of the machine and check the result:

    $ hostname beastie.localdomain.org
    $ hostname
    beastie.localdomain.org

Do not show domain information:

    $ hostname -s
    beastie

Show only domain information:

    $ hostname -d
    localdomain.org
