Set or print the name of the current host system
hostname [-s] [name_of_host]
- Trim off any domain information from the printed name.
- The name to be given to the current host system.
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.
