Hostname - System Name Utility

Show or modify the system's hostname. The hostname identifies the machine on the network and is used in shell prompts, logs, and network services.

Usage

hostname-tool [options] [new-hostname]

Running without arguments displays the current hostname. Provide a new hostname to change it (requires root privileges).

Examples

# Display current hostname
hostname-tool

# Show fully qualified domain name
hostname-tool --fqdn

# Display IP address associated with hostname
hostname-tool --ip-address
