I'll keep it going. rc was a startup script from very early times in Unix, shortened, as Ken was wont to do, from runcom, the nearest thing CTSS had to a shell--it could run up to six prespecified commands in background. The name runcom came to be applied to the scripts as well as to their interpreter.
