hostname

Set or print the name of the current host system

Syntax:

hostname [-s] [name_of_host]

Options:

-s

Trim off any domain information from the printed name.

name_of_host

The name to be given to the current host system.

Description:

When the system starts, it initializes the hostname. As superuser, you can use the hostname utility to change the hostname.

Without a name_of_host argument, hostname prints the name of the current host.

This utility sets or gets the value of the _CS_HOSTNAME configuration string, not that of the HOSTNAME environment variable.
