hostname – set or print name of current host system

SYNOPSIS DESCRIPTION EXAMPLES SEE ALSO HISTORY

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

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.

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

The hostname command appeared in BSD 4.2 .
