The term was coined by the programmers at MIT’s Project MAC. According to Fernando J. Corbató, who worked on Project MAC in 1963, his team was the first to use the term daemon, inspired by Maxwell’s demon, an imaginary agent in physics and thermodynamics that helped to sort molecules, stating, “We fancifully began to use the word daemon to describe background processes that worked tirelessly to perform system chores”.[2] Unix systems inherited this terminology. Maxwell’s demon is consistent with Greek mythology’s interpretation of a daemon as a supernatural being working in the background.
Does that command refer to the His Dark Materials thing? I thought regular demons were spelt without the a, but maybe it’s an old spelling.
