There is a configuration file that Unnethack reads during startup to set various options in the game which is named /user/home/.unnethackrc use a text editor to edit the file and you will see the sample OPTIONS command that is used to set your name. Do note you will need to become root to edit the file. I request the developer 1. Changes the config file ownership to user 2. Make sure installing updates saves a backup of the existing config file before overwriting it. Enjoy!
