Set or print the name of the current host system
hostname [-s] [name_of_host]
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. |
