hostname

QNX SDP8.0Utilities ReferenceUtilities

Set or print the name of the current host system

Syntax:

hostname [-s] [name_of_host]

Runs on:

QNX OS, Microsoft Windows

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.

Note:

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